In a balanced chemical reaction equation, is mass conserved?

Are moles conserved?

If a hydrocarbon is burned with the theoretical amount of air, can the combustion be incomplete?

If a hydrocarbon is burned with less than the theoretical amount of air, can the combustion be complete?

For the case of Example 13.1(b), is the air–fuel mixture rich or lean?

What is the equivalence ratio for the reaction of Example 13.2?

Why is the combustion of hydrocarbons considered a contributor to global warming?
