[tex] 3Ca^{2+} [/tex](aq) +[tex]2P O_{4} ^{3-} [/tex] (aq) ⇒[tex]Ca_{3} (P O_{4} )_{2} (s)[/tex]


The sum of total charges of the reactant = 3×(2+) + 2×(3-)
                                                                 = 6 + (-6)
                                                                  =0

The total charge of the balanced chemical equation will be 0.

What is balanced chemical equation?

An equation with similar amounts of each kind of atom on both sides of the arrow would be called a balanced chemical reaction. A written symbolic expression of a chemical reaction will be called a chemical equation.

The given balanced chemical equation is  __ca 2+ (aq) + __po43− (aq) → __ca3(po4)2(s).

It can be seen that, in the reactant side the count of calcium atom is 2 while in the product side it is 3. Hence, by multiply both side by 3.

The balanced chemical equation equation is :

3ca 2+ (aq) + 2po43− (aq) → ca3(po4)2(s).

The sum of total  changes of the reactant = 3× 2 + 2 × (-3). = +6-6 = 0

Therefore, the total charge will be 0.
