1.Write the balanced chemical equation for the complete combustion of C5H 12 in excess oxygen. 2. Write the balanced chemical equation for the incomplete combustion of C5H 12 in a limited supply of oxygen.

C5H12 + 8 O2 ---> 5 CO2 + 6 H2O

Explanation:

any combustion reaction reacts with oxygen to form carbon dioxide and water.

So you would write C5H12 + O2 > CO2 + H2O

(oxygen is a diatomic therefore it gets a 2 subscript)

next you just have to balance this equation (Combustions are the WORSE to balance so here you go!)

C5H12 + 8 O2 ---> 5 CO2 + 6 H2O

i'm pretty sure its b i might be wrong though!
