During the chemical process of combustion, how many (X) molecules of oxygen (O2) are needed to combine with a single molecule of the hydrocarbon pentane ( C5H12 ) thereby producing carbon dioxide and water? The chemical reaction formula for the combustion of pentane is C5H12 + X·O2 -> 5·CO2 + 6·H2O.
According to Antoine Lavoisier's conservation of mass before and after any chemical reaction the mass of any molecule must be same.
Now if we try to balance the given chemical reaction we can get
Here we clearly see that X=8.
There are 8 Oxygen molecules needed.
