the process where substances change into different substances through the breaking of chemical bonds

Chemical reaction explained in an easy to understand way.

A heat-absorbing chemical reaction, like ice melting

Endothermic reaction

A heat-absorbing chemical reaction, like ice melting. Endothermic reaction. An endothermic reaction is a process that takes in heat from its surroundings, causing the surroundings to become cooler.

States that mass cannot be created or destroyed in a chemical reaction

Law of conservation of mass

States that mass cannot be created or destroyed in a chemical reaction. Law of conservation of mass. In simple terms, this means that the total weight of stuff stays the same before and after a chemical change.
