Chemistry

The octane rating of gasoline is a relationship of the burningefficiency of the given gasoline mixture to the burning efficiencyof octane (C8H18). (Figure 1) Like most hydrocarbons, octane reactswith oxygen gas to produce carbon dioxide and water. The unbalancedequation for this reaction is

C8H18(g)+O2(g)→CO2(g)+H2O(g)

1-Determine the balanced chemical equation for thisreaction.

C8H18(g)+O2(g)→CO2(g)+H2O(g)

0.270 mol of octane is allowed to react with 0.660 mol ofoxygen. Which is the limiting reactant?

2- 0.270  of octane is allowed to react with0.660  of oxygen. Which is the limiting reactant?

octane
oxygen

3-How many moles of water are produced in this reaction?

4-After the reaction, how much octane is left?
