What is propane?What is propane?

Complete combustion takes place when Complete combustion takes place when there is excess oxygen there is excess oxygen

Incomplete combustion is when there is Incomplete combustion is when there is not enough oxygen for complete not enough oxygen for complete combustion.combustion.

When incomplete combustion occurs it When incomplete combustion occurs it forms water, carbon dioxide and carbon forms water, carbon dioxide and carbon monoxide.monoxide.

When complete combustion of propane When complete combustion of propane occurs it only forms water and carbon occurs it only forms water and carbon dioxide.dioxide.
