High temperature combustion processes, such as in combustion engines and coal-fired power plants, can result in the reaction of nitrogen and sulfur with oxygen to form nitrogen oxides (NOx) and sulfur oxides (SOx), where x can vary. These NOx and SOx compounds subsequently undergo further reaction in the atmosphere to create acidic compounds that contribute to acid rain.
(a) Do some research to determine the common products that are formed (i.e., what are the values of x) for the reactions of N and S with oxygen. Write balanced equations for these reactions.
(b) What additional reactions do these NOx and SOx compounds undergo in the atmosphere that lead to the formation of acidic compounds? Write balanced equations for these reactions.
(c) Classify each of the reactions you identified in parts (a) and (b) (precipitation, neutralization, or redox) and explain your reason for each classification.

- The atmospheric ratio of peroxyacetic nitric anhydride (PAN) to PAN + inorganic nitrite varies from less than 0.1 to 0.9. High values of the ratio are associated with photo chemically aged air masses, situations where precipitation has recently occurred, and situations were unusually high nighttime nitrogen oxide concentrations are found. What do these observations tell us  about the factors affecting the relative rates of formation and removal of nitrogen oxide compounds?arrow_forwardHydrocarbons with 5 carbons (pentane) and 19 carbons (nonadecane) are liquids at room temperature. The molecules with 8, 9, and 10-carbons are "octane", "nonane", and "decane" and are common components of gasoline. The image below shows chemical equations for the combustion of the simplest hydrocarbon methane, 3-carbon propane, and 10-carbon decane. As you can see, the products are always carbon dioxide and water, just in larger amounts for larger hydrocarbons. Question: how many carbon dioxide molecules are formed from combustion of one molecule of decane? Methane CH4 + 202 → CO2 + 2H2O Propane C3H3 +502 – → 3CO2+4H2O C10 H22 + 15.502 10CO2 + 11H20 Decane -arrow_forwardOzone in the lower atmosphere is a pollutant that can form by the following reaction involving the oxidation of unburned hydrocarbons:CH4(g) + 8 O2(g)-------->CO2(g) + 2 H2O(g) + 4 O3(g)Use the standard free energies of formation to determine ΔG°rxn for this reaction at 25 °C.arrow_forward

- When copper and sulfur react, two products are possible: copper(I) sulfide, Cu2S, and copper(II) sulfide, CuS. A scientist hypothesizes that holding a loop of thin copper wire in the vapour from boiling sulfur will produce pure Cu2S when the copper and sulfur react. Suggest what measurements, related to mole ratios, the scientist should make to test this hypothesis.arrow_forwardWhat mass of nitrogen monoxide would be produced by complete reaction of 17.0 g of ammonia?arrow_forwardTrans-oleic acid (18:1,D9) has a melting temperature of (44.5C) and cis-oleic acid (18:1,D9) has a melting point of (13.4C).
