What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings.

Front

What is a combination reaction?

Back

A combination reaction is a type of chemical reaction where two or more substances combine to form a single product, represented by A + B → AB.
