A. Burning a piece of paper is technically called combustion. It represents a chemical reaction whereby the carbon compounds in the paper are oxidized into different chemicals like carbon dioxide and water vapor. This is a chemical change.

As the paper decomposes it will char or turn brown to black as the cellulose polymer degrades.
