Document Summary

Gasoline - a very complex mixture of compounds, but contains predominantly alkanes. Alkanes - hydrocarbons where the carbon atoms are linked together with single bonds. Hydrocarbon - compound composed only of hydrogen and carbon. Alkanes general formula = cnh2n+2 n is an integer. Saturated hydrocarbons only c to c single bonds. Isomers are compounds that have the same chemical formula but are connected differently. Complete combustion of octane with excess oxygen produces carbon dioxide and water. Incomplete combustion with limited oxygen produces carbon monoxide and water. Stoichiometry - a term used to describe quantitative relationships in chemistry. Do ratio of moles and substitute coefficient from equation for original and final molecule. Convert final molecule from moles to grams. Grams1 moles1 moles2 grams2. In many reactions, one reactant is often exhausted (used up) before the other reactants. The reactant used up first is the limiting reactant. Once the limiting reagent is consumed, the reaction stops.
