2. The octane rating of gasoline is a relationship of the burning efficiency of the given gasoline mixture to the burning efficiency of octane (C8H18C8H18). Like most hydrocarbons, octane reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is

C8H18(g)+O2(g)CO2(g)+H2O(g)

B. 0.160 molmol of octane is allowed to react with 0.680 molmol of oxygen. Which is the limiting reactant?

C. How many moles of water are produced in this reaction? Express your answer with the appropriate units.

After the reaction, how much octane is left? Express your answer with the appropriate units.

D. How many grams of water are needed to react with 0.372 molmol of ethylene?
