How do you know if a chemical reaction is balanced ?
Alenkasestr [34]

Hey there!

We know that a chemical reaction is balanced when there is the same amount of each element on both sides of the equation.

According to the law of conservation of mass, matter cannot be created or destroyed, so we must have the same amount of each element on each side of a chemical equation.

We count the amount of each element on each side, and the products should have the same number as the reactants.

Hope this helps!
