Question

When an object is burning, two atoms of oxygen (in the air) combine with one atom of carbon (from the

substance burning). This forms carbon dioxide gas. Explain how the law of conservation of matter applies to

this reaction.

2. A piece of wood is burned, and a small amount of ashes are formed. Explain why the original piece of wood

and the resulting ashes will not weigh the same.

Answer 1

2. as the log burns it forms ash but it also forms a lot of carbon dioxide gas which escapes into the air. The loss of this gas means that the final mass of the ash is less than the mass of the log and the oxygen used to burn it.
