ammonium nitrate decomposition reaction equation

Use 1 mL of each solution unless otherwise specified. Write a balanced equation for this reaction. Removal of nitrate from the soil by leaching has several consequences. Solid ammonium nitrate decomposes on heating. Balancing Strategies: In this decomposition reaction, NH4NO3 is breaking apart (decomposing) into N2 + O2 + H2O. NH4NO3 - > 2H2O + N2O, However a passing shockwave can induce this decomposition in a large quantity of ammonium nitrate at once, which is a detonation. This reaction occurs as the match ignites, causing the match head to be surrounded by an oxygen atmosphere. Some relatively simple but common types of chemical reactions are illustrated in this experiment. Clay particles usually have negative charges because of unsatisfied valences at the crystalline edges of the silica and alumina plates. Two clay particles in close proximity can be held together by the dissolved cations that are attracted to both the surfaces. The Journal of Physical Chemistry, Guy Marlair, Marie-Astrid Kordek, "Safety and security issues relating to low capacity storage of AN-based fertilizers,", Zhe Han, "Thermal Stability Studies of Ammonium Nitrate,", Alex M. Djerdjev, Pramith Priyananda, Jeff Gore, James K. Beattie, Chiara Neto, Brian S. Hawkett, "The mechanism of the spontaneous detonation of ammonium nitrate in reactive grounds,". The nitric acid is titrated with a standardized sodium hydroxide solution to a phenolphthalein endpoint or a pH endpoint. Overall agronomic experiments show only small differences in crop utilization of N from urea compared with nitrate-containing fertilizers. The hydroxides of Group IA and barium are soluble. The reactions that describe the decomposition of ammonium carbonate ((NH_4)_2CO_3) are: (NH_4)_2CO_3(s) -> NH_4HCO_(3(s)) + NH_(3(g)) (1) NH_4HCO_(3(s)) -> Ammonium, nitrate, and phosphorus are plant-availabe nutrients that are found in wastewater and are frequently associated with excessive algae growth in surface waters. Displacement reactions are also classified as oxidation-reduction reactions. This includes the containers, impurities, soot and debris from the fire, etc. 2NH 4 NO 3 2N 2 + 4H 2 O + O 2. Short of that, NH4NO3 is a relatively weak explosive, but it comes in great quantities, hence the effect. Hazardous scenarios with ammonium nitrate can involve simple thermal decomposition initiated by external fire or other heating, self-sustained decomposition also known as "cigar burning," and detonation. and roofing material might have mixed with the FGAN pile. However, microbial processes can convert ammonium to nitrate (nitrification). When nitrate is leached, it must be accompanied by an equivalent amount of cations to maintain charge balance. Plant uptake is a reliable means of removing nitrate during the growing season. (3 marks) Ques. But apparently there have been accidental explosions involving just the "fertilizer". You'll need to get the odd number of O atoms to an even number by multiplying by "2". decomposition reactions become increasingly more complex. The John A. Dutton e-Education Institute is the learning design unit of the College of Earth and Mineral Sciences at The Pennsylvania State University. Using the VSEPR theory and the diagrams above, -state and explain the geometries of the NH 4 + and NO 3 ions shown. ________>________>________>________>________, most active (most easily oxidized) to least active. the FGAN pile in the main bin and possibly in an adjoining bin linked to the main bin through a series of When one thinks of fire and dissects the requirements of a fire into a fuel and an oxidiser, this is in chemical terms only a different way of determining an oxidising agent and a reducing agent in a redox reaction. WebNH 4 NO 3 N 2 + O 2 + H 2 O. The second source of electronegativity is the isomorphous substitution of Mg2+ for Al3+ or Al3+ for Si4+. holes cut in the partition between the bins. For example, sodium phosphate can be used in an exchange reaction to precipitate calcium ions out of hard water as calcium phosphate, a reaction that is used in some commercial water softeners. Webat ~23% ammonium nitrate decomposition; and at 230oC at 14%. What are the other chemical substances that are formed in the process of making ammonium nitrite? Why did the Soviets not shoot down US spy satellites during the Cold War? and exothermic decomposition reactions that take place with increasing temperature. If decomposition happens at supersonic rates, this leads to a shockwave characteristic of a detonation. Ions of similar size (atomic radii) can substitute for the silicon ion in the tetrahedral layer and for the aluminum in the octahedral layer (Essington, 2004). Thus, it is recommended thatblasters perform a cup-density check frequently, e.g., every 5 or so holes in a surface mine application. Dalsze korzystanie ze strony oznacza, e zgadzasz si na ich uycie. The US CSB West Fertilizer Explosion final report, section 4.3, outlines three possible scenarios under which the 2013 explosion in West, Texas could have occurred. However, they are capable of reacting and they have thermodynamically favourable reaction pathways as Matthews answer nicely outlines. Record your observations on the data page as you complete each reaction. At temperatures below around 300 C, the decomposition mainly produces nitrous oxide and water: NH 4 NO 3 N 2 O + 2H 2 O. To identify the products formed in chemical reactions and predict when a reaction will occur. Regardless, $\ce{NH4NO3}$ is not considered a flammable or combustible material at ambient temperature and pressure (Ref.1). Scenario 2: Detonation in heated FGAN along exterior wall exposed to fire. The sulfates of lead(II), barium, and calcium are insoluble. Then write a balanced equation for each reaction. In this review data from the literature on thermal decomposition of ammonium nitrate (AN) and the effect of additives to their thermal decomposition are summarized. This layer of water is not plant available water; plant roots cannot extract this water off the clay particle. $$\ce{NH4NO3 -> 3/4N2 + 1/2NO2 + 2H2O } \quad \Delta H = \pu{-944 kJ/mol} \tag5$$. [ Check the balance ] The thermal decomposition of ammonium nitrate to produce nitrogen, water and oxygen. To write balanced equations for the reactions studied. The relative activities of metals can be tabulated in an activity series, ranking the metals by relative ease of oxidation. expected when FGAN undergoes thermal decompositionsuch as NO2, O2, and HNO3 as wells as fuelrich smoke and pyrolysis products off-gassing from the molten FGAN. For instance, the reaction $(3)$ can be made more exothermic ($\pu{789 kJ/mol}$) with more gaseous products, if some oxidisable fuel is added such as $\ce{C}$ (Ref.3): $$\ce{2NH4NO3 (s) + C (s) -> 2N2 (g) + CO2 (g) + 4H2O (g)} \tag8$$. Using the VSEPR theory and the diagrams above, -state and explain the geometries of the NH 4 + and NO 3 ions shown. Rao, in Encyclopedia of Toxicology (Third Edition), 2014. Silicate clays are generally aluminosilicates. Remove the tube from the flame and quickly and cautiously note the smell. The clay particle essentially becomes an anion and is the inner layer. As an example, potassium chlorate decomposes when heated to yield potassium chloride and oxygen gas. The heat of reaction is utilized for evaporation and 8083% ammonium nitrate solution is obtained. Under certain conditions, phosphorus can be bound to clay surfaces. The strength of the bond that holds clay particles together is a function of the distance between the particles and valence of the ions. en.wikipedia.org/wiki/Ammonium_nitrate_disasters, en.wikipedia.org/wiki/Texas_City_disaster, https://en.wikipedia.org/wiki/2020_Beirut_explosions, https://doi.org/10.1016/j.jhazmat.2005.03.028, https://doi.org/10.1016/j.jece.2017.12.003, US CSB West Fertilizer Explosion final report, reportedly there were fireworks stored in the same warehouse. Ammonium nitrate (NH4NO3) is produced by neutralizing nitric acid (HNO3) with ammonia (NH3). The percentage ammonium sulfate can be determined by the reaction of formaldehyde, which produces sulfuric acid. I thought ammonium nitrate was an oxidizer that needed to be mixed with fuel to form a high explosive (e.g., ANFO). Several examples of displacement reactions are given below. You should definitely read the report; my brief summary below leaves a lot of relevant analysis out. Use a test tube holder to hold the tube at about a 45, 0.1 M silver nitrate and 0.1 M sodium chloride, 0.1 M nickel(II) nitrate and three drops of 6 M sodium hydroxide, 0.1 M lead(II) nitrate and 0.1 M potassium chromate. 3. The hot granules are dried in a rotary drier by hot air, screened and cooled in coolers to obtain the product. Two electrons are transferred from lead to copper in this process: \[ \ce{Pb (s) -> Pb^{2+} (aq) + 2 e^-} \quad \quad \text{oxidation of lead}\], \[ \ce{Cu^{2+} (aq) + 2e^- -> Cu (s)} \quad \quad \text{reduction of copper}\]. WebPure ammonium nitrate does not explode easily and can be handled safely. Like ammonium, nitrate has many competing fates in the soil ecosystem (Fig. 2. This solution contains a swarm of ions a portion of which are cations trying to balance the surface charges. A metal that displaces hydrogen gas from acid is more active than hydrogen. \[\ce{Sn(s) + HCl(aq) -> H2(g) + SnCl2(aq)} \quad \quad \quad \text{______ >______}\], \[\ce{Au (s) + Sn(NO3)2 (aq) ->} \text{NR} \quad \quad \quad \quad \text{______ >______}\], \[\ce{Au(s) + HCl ->} \text{NR} \quad \quad\quad \quad \text{______ >______}\], \[\ce{Zn (s) + Sn(NO3)2 (aq) -> Zn(NO3)2 (aq) + Sn (s)} \quad \text{______ >______}\]. If you want to learn more about the chemistry behind ammonium nitrate explosions, Ive provided some useful links below. Mixtures containing urea can also explode. In some cases, solutions may be blended for marketing as liquid fertilizers. The manufacturer of the ammonium nitrate would be able to give you that information, or you could do a simple experiment in the lab to determine the density of that mix. | Socratic. WebAmmonium nitrate melts at 337 deg F (170 deg C) and begins to undergo decomposition when molten. have come in contact with molten FGAN. What are the other chemical substances that are formed in the process of making ammonium nitrite? contamination of the FGAN pile. It is believed that the vaporization of molten $\ce{NH4NO3}$ leads to the formation of ammonia and nitric acid, which could initiate the decomposition of $\ce{NH4NO3}$ through following reaction: $$\ce{NH4NO3 <=> HNO3 + NH3} \quad \Delta H = \pu{176 kJ/mol} \tag2$$. A fiberglass lid With the dark smoke inside of the structure reduced, radiant heat At some point around 5 to 6 minutes before the detonation, the character of the fire changed, according to So yeah, the TLDR here is that conditions in a fire can be extremely complicated and unpredictable, giving rise to a lot of opportunities for contamination and detonation. Chlorides, Bromides and Iodides are soluble. This is at the core of your question. This paper 1 notes that the irreversible decomposition of ammonium nitrate occurs at the temperature range of $\pu {230-260 ^\circ C}$. The following reaction has been hypothesized as the main detonation reaction: 2NH 4 NO 3 2N 2 + O 2 + 4H 2 O. This interest has been stimulated by the demand for ammonium nitrate as a fertilizer component and as an ingredient in explosives. The limited ventilation increased the quantity of soot in the smoke and the potential Mathew's answer below has some more reaction formulas with enthalpy changes and other info. NH 4 NO 3: molecular weight = 80.05 g/mol CH 2: molecular weight = 14.03 g/mol The ideal mixture, i.e., the oxygen-balanced mixture, consists of 3 moles of ammonium nitrate and one mole of fuel oil. Also, until now, their high cost has precluded their use from normal agricultural crops; they are used to some extent to make fertilizer N slowly available to certain high-value horticultural crops. Give a balanced equation for the decomposition reaction. Martin B. Hocking, in Handbook of Chemical Technology and Pollution Control (Third Edition), 2005. In the context of Beirut explosion, the question that raised was "when did ammonium nitrate reached detonation temperature, and why did it suddenly explode?". This is an important consideration because wastewater could have a significant quantity of monovalent cations such as sodium from salt and water softeners. releases huge amounts of energy.[]. There were also flashes and bangs and a lot of other stuff going on there (reportedly there were fireworks stored in the same warehouse). $$\ce {NH4NO3 -> [t >230 ^\circ C] N2O + 2H2O}$$ Does Cast a Spell make you a spellcaster? Therefore, the number that you need to give to your blaster is 0.42 lb. This reaction takes place at a temperature of over 300C. The Pennsylvania State University 2020, Module 1: Introduction to the Mining Industry, Module 2: The Life Cycle of a Mine and Related Matters, 6.2.1: Mixing ANFO and the Oxygen Balance, 6.2.3: Classification of Common Industrial Explosives, 6.2.5: Key Properties Affecting Choice of Explosives, Department of Energy and Mineral Engineering, Department of Materials Science and Engineering, Department of Meteorology and Atmospheric Science, Earth and Environmental Systems Institute, Earth and Mineral SciencesEnergy Institute, iMPS in Renewable Energy and Sustainability Policy Program Office, BA in Energy and Sustainability Policy Program Office, 2217 Earth and Engineering Sciences Building, University Park, Pennsylvania 16802. poor quality control at the batch mixing truck; incorrect formulation, for example by adding a sensitizer like aluminum, but not accounting for it in the addition of the fuel oil; improper timing of adjacent holes, allowing the explosive to become unconfined by the time it detonates; explosives at the collar of the hole (increases fume production, not fragmentation). Can the Spiritual Weapon spell be used as cover? WebAs ammonium nitrate is a salt, both the cation, NH 4+, and the anion, NO 3, may take part in chemical reactions. Potassium chlorate is one of the ingredients used in match heads. The sulfuric acid can be titrated with sodium hydroxide to determine the amount of ammonium sulfate present. Ammonium nitrate is the nitrate salt of the ammonium cation (NH4NO3, sometimes written as N2H4O3) that is a white crystal solid and is highly soluble in water. The main point of this answer is to use the 2013 West Fertilizer Company explosion (USCSB animation for context) as an example of scenarios that could lead to AN detonation, and also to show that the situation can become very complex and unpredictable. The ideal mixture, i.e., the oxygen-balanced mixture, consists of 3 moles of ammonium nitrate and one mole of fuel oil. FGAN storage area can include ignitable liquids, finely divided metals or organic materials, chloride So from section 4.2, contributing factors (FGAN = fertilizer grade ammonium nitrate): In fire situations, the behavior of FGAN is unpredictable, in part because of the number of endothermic Soil chemistry is the interaction between soil solution and solid phase. Initial reports say it was caused by "2750 tons of stored ammonium nitrate". Displacement of hydrogen gas from an acid by a metal: Displacement of hydrogen gas from water by a metal: Do not stare directly at the magnesium when it burns as the light can hurt your eyes. \[\ce{HCl (aq) + NaOH (aq) -> NaCl (aq) + H2O (l)}\], Solids: \(\ce{Mg}\), \(\ce{CuSO4*5H2O}\), \(\ce{Ca}\), \(\ce{Cu}\), \(\ce{Zn}\), \(\ce{NaHCO3}\) <> Scenario 3: Detonation in elevator pit that spread to main FGAN bin. The common cations adsorbed by clay surfaces are H+, Al3+, Ca2+, Mg2+, K+, and Na+. The other Group IIA hydroxides are moderately soluble to insoluble. One reason that ammonium nitrate is so explosive is that it contains in the same molecule both a fuel, in the form of the ammonium ion, and a strong oxygen- producing agent, nitrate. Komendy CS GO. The following reactions are performed, and the results are shown below. You might have wonder what caused the plume of smoke seen after the explosion in Beirut to have an orange-red colour. For reactions involving metals, use just one piece of metal. Solutions: 6 M \(\ce{HCl}\), 6 M \(\ce{NaOH}\), 6 M \(\ce{H2SO4}\), 1 M \(\ce{NH4NO3}\), and 0.1 M solutions of \(\ce{CuSO4}\), \(\ce{ZnSO4}\), \(\ce{AgNO3}\), \(\ce{NaCl}\), \(\ce{Ni(NO3)2}\), \(\ce{Pb(NO3)2}\), and \(\ce{K2CrO4}\), Equipment: crucible tongs, one large test tube, two small test tubes, ten small test tubes, test tube holder, test tube rack, 100-mL beaker, red litmus paper, Bunsen Burner Recall that a more active metal displaces a less active metal, a more active metal to is needed to displace hydrogen from water than to displace it from an acid, and that a metal that displaces hydrogen from acid is ranked as more active than hydrogen. Task 2 Decomposition or explosion? Examples are shown in Figures 5-7. Exchange Reactions (also called Double Replacement or Metathesis Reactions) occur when two compounds that form ions in solution react by switching ion partners. Jak zwikszy FPS W CS GO? Word equation: Ammonium nitrate Nitrogen gas + Oxygen gas + Water. Reportedly there were fireworks stored in the same warehouse as the AN in Beirut: So ammonium nitrate by itself is considered a low explosive, but has potential to detonate (ie, be a high explosive) under the right conditions? Water is always a product when the base contains the hydroxide ion (see example below). Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. The ammonium is then nitrified within 23weeks. Be sure to include the states of all compounds in your equations (solid, liquid, aqueous, or gas). If the However, as discussed earlier in this chapter, the limiting factor with fine-textured soils is getting the effluent in contact with the surface area. @Nilay Do you consider your theory of the ammonium nitrate exploding on its from heat in Beirut more likely than it being combined with a fuel? Odbierz DARMOWE przedmioty w ulubionej grze! However, it is a strong oxidizing agent that can detonate under certain conditions such as temperature, fire, confinement, and presence of impurities (e.g., $\ce{KCl}$), which can be act as a promoter to detonate (Ref.2). The leaching of basic cations, such as K+ and Ca2+, reduces the base saturation of a soil and increases exchangeable acidity. | Socratic. In Beirut, there was a significant and long fire prior to the explosion, so another theory involving contamination could also be possible, I think, since there was plenty of fuel sources, and the suggestion of gradual heating. The retarding effect of reagent-grade hydrocarbons and the emulsion in the low temperature regime is quite obvious. An explosion goes straight to N2 and O2. If no reaction is expected, indicate this and explain why no reaction is expected. If needed, crops with high nitrate uptake can be planted and harvested to maintain an appropriate nutrient balance. Gas Forming Reactions typically go to completion because one or more of the products are removed from the reaction vessel via the formation of a gas, which leaves the reaction mixture as bubbles. Once ammonium nitrate starts to decompose, a runaway reaction may occur as the heat of decomposition increases. However, with urea some N may be lost as ammonia gas under some circumstances and slightly more may be absorbed by microorganisms as they tend to take up ammonium rather than nitrate if both are available. Ammonium nitrate is used commonly in fertilizers; in pyrotechniques, herbicides, and insecticides; and in the manufacture of nitrous oxide. When the ammonium nitrate stores exploded, a white condensation cloud spread out in a sphere from the site, followed by a huge plume of red-orange smoke rising from the hanger. The containers can be destroyed by fire allowing AN to escape into unpredictable places. For example, in the first reaction given above, elemental lead is oxidized to lead(II) and copper is reduced from copper(II) to elemental copper. It only takes a minute to sign up. Products are sometimes coated with clays or diatomaceous earth to prevent agglomeration during storage and shipment, although additives may eliminate the need for coatings. This is a requirement the equation must satisfy to be consistent with the law of conservation of matter. J.R. Buchanan, in Comprehensive Water Quality and Purification, 2014. And from section 4.3, a few detonation scenarios: Based on the location of the pile and the properties of the bin along with the circumstances of other fire induced incidents, one possible scenario is that a period of contamination with soot and other organics It is very, very conceivable that the AN became both heated enough and contaminated enough during this time to detonate. The solubility of the substances. detonation began in the pit, then the most feasible mechanism would be a collapse of the west wall of the 11.52). WebAmmonium nitrate melts at 337 deg F (170 deg C) and begins to undergo decomposition when molten. Type of Chemical Reaction: For this reaction we have a decomposition reaction. Because it is an anion, nitrate is easily leached. Nitrate that leaches eventually enters ground and surface waters, where it may have potentially adverse environmental effects. endobj | Socratic. major increase in heat radiation inside the fertilizer building because of increased oxygen availability to However, if it is contaminated with impurities, the risk of it detonating increases. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. More powerful, or simply easier to detonate, or both? Not all of the combinations will yield observable reactions. For example, plants producing ammonium nitrate solutions alone use only the solution formation, solution blending and bulk shipping operations. N2O can be obtained by slow controlled decomposition. The additional ventilation caused a marked decrease in dark smoke and probably was accompanied by a 1 M ammonium nitrate and 6 M sodium hydroxide. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. I just emphasized on the heat part and other answers explored the other factors, like oxidation + fuel part is explained in Alchimista's answer, the thermodynamics is explained in Mathew's answer. Explorations of everyday chemical compounds, Rashes and burns: summer plant irritants in C&EN, Lebanese Red Cross is accepting donations, Impact Lebanon are raising disaster relief funds, The graphic in this article is licensed under aCreative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License. However, as per. One reason that ammonium nitrate is so explosive is that it contains in the same molecule both a fuel, in the form of the ammonium ion, and a strong oxygen- producing agent, nitrate. <>/OutputIntents[<>] /Metadata 209 0 R>> Thus, the nitrogen in nitrate will, as part of a redox reaction reduce its oxidation state by taking up electrons. The exploded $\ce{NH4NO3}$ was coated with (carbon based) wax to prevent caking (See equation $(8)$ above). $$\ce {NH4NO3 -> [t >230 ^\circ C] N2O + 2H2O}$$ It will also explode more readily if contaminated or mixed with combustible materials such as fuel oil, the latter known as ANFO. WebPure ammonium nitrate does not explode easily and can be handled safely. 1 0 obj The ease with which a substance is oxidized is quantified as its standard oxidation potential; you will learn more about this in the second semester of General Chemistry. greatly increase the radiant heat flux by raising the temperature of the burning wood. might have melted the cover, and FGAN remnants could have been in the pit. Beirut explosion: What is ammonium nitrate and how dangerous is it? From most active (most easily oxidized) to least active: Now use the above results to write products for the reactions below. It is known that ammonium nitrate decompose exothermically when heated to form nitrous oxide and water. Place a small amount (an amount that will fit on the end of a spatula) of solid copper(II) sulfate pentahydrate in a medium test tube. Here is a list of other AN accidents that you could research on your own to find out about other scenarios that can lead to detonations. The %N from ammonium sulfate is determined by multiplying the percentage ammonium sulfate by 0.212. Are these explosions also detonations? The number of operating steps employed depends on the specification of the product. What is the balanced equation for ammonium carbonate is heated, it decomposes into ammonia gas, carbon dioxide gas, and water vapor? This paper 1 notes that the irreversible decomposition of ammonium nitrate occurs at the temperature range of $\pu {230-260 ^\circ C}$. Divalent cations (i.e., Ca2+ and Mg2+) tend to have a small ionic radius and thus allow the particles to be close together and form a strong bond. Clay particles are the reactive portion of the soil; sand and silt comprise the soil skeleton. Paul N. Cheremisinoff P.E., D.E.E.Professor, in Waste Minimization and Cost Reduction for the Process Industries, 1995. At temperatures below around 300 C, the decomposition mainly produces nitrous oxide and water: NH 4 NO 3 N 2 O + 2H 2 O. Word equation: Ammonium nitrate Nitrogen gas + Oxygen gas + Water. Warm the test tube gently by passing it back and forth through a burner flame. It is a sad and quite devastating incident. Examining ammonium nitrate reveals that there is another nitrogen atom in the ammonium cation which is in the $\mathrm{-III}$ oxidation state. If nitrate is a concern then, effluent application should be limited to the agronomic requirement of the plants in the soil absorption area, and then a large fraction of the plant biomass should be removed each year to prevent the organic nitrogen from being mineralized upon plant decomposition. $$\ce{NH4NO3 -> N2O + 2H2O } \quad \Delta H = \pu{-59 kJ/mol} \tag3$$, $$\ce{NH4NO3 -> 1/2N2 + NO + 2H2O } \quad \Delta H = \pu{-2597 kJ/mol} \tag4$$, $$\ce{NH4NO3 -> 3/4N2 + 1/2NO2 + 2H2O } \quad \Delta H = \pu{-944 kJ/mol} \tag5$$, $$\ce{2NH4NO3 -> 2N2 + O2 + 4H2O } \quad \Delta H = \pu{-1057 kJ/mol} \tag6$$, $$\ce{8NH4NO3 -> 5N2 + 4NO + 2NO2 + 16H2O } \quad \Delta H = \pu{-600 kJ/mol} \tag7$$. Type of Chemical Reaction: For this reaction we have a decomposition reaction. When the ammonium nitrate stores exploded, a white condensation cloud spread out in a sphere from the site, followed by a huge plume of red-orange smoke rising from the hanger. Web1. In addition to the production of toxic gas, the energy release is reduced. 2NH 4 NO 3 2N 2 + 4H 2 O + O 2. Use 1 mL of each solution unless otherwise specified. In each case one of the products results by combining two ions that are removed from the solution by the reaction. Potassium chlorate is one of the ingredients used in match heads.
