Question

Which equation correctly represents the combustion of butane c4h10 in excess oxygen?

Answer 1

CxHyOz + O2 --> CO2 + H2O

We know that when butane is burned, the byproducts of the reaction are always H2O (water) and cO2 (Carbon Dioxide) thus the reaction if butane is burned when excess oxygen is present in the surroundings, the reaction would be:

2C4H10(g) + 13O2(g) --> 8CO2(g) + 10H2O(g)
