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.
Burning is a chemical reaction in. which fuel reacts with oxygen, producing carbon. dioxide, water and several other products. The energy released comes from the rearrangement. of atoms. There is less energy stored in the chemical. bonds in the products than there was in the reactants. Chemical reactions that release energy are called. exothermic reactions. Chemical reactions in which energy is absorbed from. the surroundings are called endothermic reactions. There. is more energy âstoredâ in the chemical bonds of the. products than there was in the reactants.
