Chemical bonds always break in chemical reactions, causing changes in energy.
There will always be changes in one of the reactants. In some chemical reactions, one of the chemicals works as a catalyst to encourage a reaction between two or more chemicals but does not change during the reaction.
Burning is a chemical change: involve oxidation reactions and thermal decomposition reactions.
Cleaning is a physical process but sometimes can involve chemical reactions.
Chemical reactions are chemical processes.
When an apple rots, it's more of a chemical change. Sure, you can SEE the change in it..but the look, is not the actual change. It is a chemical change, catalysed by an organism. The apple wouldn't rot, if there were no chemical change.

Chemical bonds always break in chemical reactions, causing changes in energy.
Pasteurization involve chemical reactions.
Cooking involve chemical reactions.
There will always be changes in one of the reactants. In some chemical reactions, one of the chemicals works as a catalyst to encourage a reaction between two or more chemicals but does not change during the reaction.
Corrosion involve chemical reactions - and these are chemical changes.
Burning is a chemical change: involve oxidation reactions and thermal decomposition reactions.
There are many different possible property changes in a chemical change. You must post the specific reaction for anyone to tell you exactly.
Because cooking involve also chemical reactions.
Baking is a chemical change because involve chemical reactions.
A physical change doesn't involve chemical reactions, change of the molecule structure.The chemical reactivity is about the ability of an element or compound to realize chemical reactions.
Ripening is a chemical process.Ripening involve many chemical reactions.
