Study Notes

Chemical Equations

The process of balancing a chemical equation is called balancing a chemical equation.
In a balanced chemical equation, the total mass of the products is equal to the total mass of the reactants.
The coefficient in a chemical equation represents the number of molecules or atoms of a substance involved in the reaction.
The purpose of balancing a chemical equation is to ensure that the number of atoms of each element is the same on both the reactant and product sides of the equation.
Balancing a chemical equation is important because it ensures that the law of conservation of mass is followed, which states that matter cannot be created or destroyed, only converted from one substance to another.

Story
