balancing this chemistry equation ( HELP PLEASE!)?

Question

C5H10 + O2 ----> CO2 +H2O



C5H10 + O2 -----> Co2 + H2O


I don't really know if it is CO2 or Co2...so yeah....if someone can help me with both, that would be great!

Answer 1

Well in both cases, they have to be CO2 which is carbon dioxide. Whenever you burn anything that contains carbon and hydrogen, you'll form carbon dioxide and water.

Since you have 5 carbon atoms on the left, you'll form 5 CO2 molecules. Since you have 10 H atoms on the left, you'll form 5 H2O. But that gives you 15 oxygen atoms on the right, which would be 7.5 O2 molecules. It will be best to put a 2 in front of the C5H10, a 15 in front of O2, a 10 in front of CO2 and a 10 in front of H2O.
