When butane (C4H10) burns, it creates carbon dioxide and water (CO2 and
H2O). All of the elements are still there, they are just rearranged as matter can neither be created nor destroyed from a chemical reaction.
When methane (CH4) burns, you also get carbon dioxide and water.
In these reactions where the byproducts are CO2 and H2O, are these products affected by changes in the overall quantity of the organic reactants being used?
