Textbook QuestionHigh 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.372views

Textbook QuestionCobalt(II) chloride, a blue solid, can absorb water from the air to form cobalt(II) chloride hexahydrate, a pink solid. The equilibrium is so sensitive to moisture in the air that CoCl₂ is used as a humidity indicator. Write a balanced equation for the equilibrium. Be sure to include water as a reactant to produce the hexahydrate.622views
