The Law of Conservation of Mass is one of the main guidelines in chemistry
The law states that in a chemical reaction the number of atoms in the reactants(what is mixed together) must match the number of atoms in the products (what is created)

Types of Chemical Reactions
There are many types of chemical reactions that produce a wide variety of different substances. Sometimes, scientists need to be able to know exactly how to do a specific type of reaction in the lab.
Balancing Chemical Equations
Scientists need to make sure that both sides of the equation are balanced in order to fulfill the Law of Conservation of Mass.
Without balancing both sides of the equation, scientists will use the wrong amount of sample in the experiment causing the experiment to fail or worse.
