(8 x 2) on the reactants side as well. Now the only unbalanced one is Chlorine. On the left hand side, there are 16 Cl. On the right hand side, firstly, there are 2 Cl in 2 KCl + 4 Cl in 2 MnCl 2 , making total of 6(2 + 4). Subsequently 10 more Cl atoms are to be accounted for. So place 5 in front ..
