What gets heavier when it is burnt?

[gen2]

Answer 1) - Everything

When a substance burns, Oxygen is combined with the original substance so the products are going to be heavier than what was burnt

Answer 2) - Nothing

If you include the weight of the original oxygen that is needed to combine with what is burnt, then the total weight of the ingredients = total weight of the products.

Answer 3) - ???????????

Do you want to quibble about the distinction between mass and weight? I'm not in the mood right now.
