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.

- Hydrocarbons 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_forwarduestion (1 point) e See section 9.8 A number of reactions can be used to generate common gases on a laboratory scale.
