Exothermic reactions. E.g. combustion, oxidation
A chemical change is one that creates compounds (products) that are different from the reactants. A physical change only alters the form or phase of the existing substances, not their chemical properties.
The rotting of wood is a chemical change because of many reasons. One of the reasons is because when wood rots, it produces mold, which is a new substance. The definition of chemical change is a change that produces one or more new substances. When the wood rots, you are unable to take the rotted wood and mold and make it back into wood that is yet to be rotted. So because the wood produces one (or more) new substances, the rotting of wood is a chemical change.
This is a chemical change.
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Baking is a chemical change because involve chemical reactions.

Nuclear and Chemical changes result in new substances.
A mixture that produces a chemical reaction, scientifically speaking, is a chemical change.
it produces other chemicals
A chemical change produces a new substance. This occurs when the original substances undergo a chemical reaction, resulting in the formation of new substances with different chemical properties.
it is a chemical change because it produces gases
A chemical change produces a new substance with different chemical properties from the original substances. This change involves the breaking and forming of chemical bonds. Examples of chemical changes include burning wood, baking a cake, and rusting of iron.
