Question

Heptacarbon octahydride is an effective gasoline additive. In the presence of oxygen gas (and a spark), it undergoes complete combustion.

a. Write a balanced equation for this reaction. Identify the oxidizing agent (oxidizer) and the reducing agent (reducer).

b. Calculate the theoretical yield of water (in g) when 500 g of heptacarbon octahydride reacts with an excess of O2.

c. Calculate the mass of oxygen gas necessary to produce a theoretical yield of 1.00 lb of carbon dioxide.
