What are some indicators that a chemical reaction has occurred?

1.Combustion fuel + oxygen  carbon dioxide + water vapour + energy 2.Neutralization acid + base  salt + water 3.Simple Composition Reaction – Two or more elements combine to form a compound. Whenever you see two elements as reactants, you know that the reaction is a simple composition reaction. 4.Simple Decomposition Reaction – A reaction that breaks a compound into its component elements.
