Remember the Law of Conservation of Mass. This means that the given number of atoms and elements on both sides of the reaction eq'n MUST be the same.

It is also known as a BALANCED EQUATION.

e.g.

2KOH + H2SO4 = K2SO4 + 2H2O

In this case the prefix '2' of KOH, indicates that there are 2 x K , 2 x O & 2 x H. The suffix '2' in H2SO4 indicates 2 X H , only 1 x S & 4 x O.

So overall on the reaction side we have

2 x K

6 x O

4 X H

1 x S .

You MUST end up with this same numbers on the product side.

Hence we have in K2SO4 , 2 x K, 1 x S , & 4 x O. The prefix '2' of H2O indicates that there are 2 x 2 = 4 H & 2 x 1 =2 O

Hence, overall we have on the product side

2 x K

4 + 2 = 6 x O

4 x H

1 x S

This agrees with the reactant numbers and elements, so the chemical reaction equation is balanced.

Hope that helps!!!!

What information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction?

The information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction is the number appearing immediately before the formula for the reactant in question in the chemical equation. This number is called a "coefficient".
