ok thanks can u give me example :)
Cu^2+ + SO4^2- + Ca^2+ + 2(OH)^- →Cu(OH)2+CaSO4

Reactant:
Cu=2
Cu^2+ + SO4^2- + Ca^2+ + 2(OH)^- →Cu(OH)2+CaSO4

Reactant:
Cu = 1
S = 1 +2(1) = 3
O = 4 + 2(1) = 6
Ca = 1
H = 2

Product:
Cu = 1
O = 1(2) + 4 = 6
Ca = 1
S = 1
H = 2
Correction

Reactant:
S = 1

Product:
S = 1
