In this reaction, the caesium displaces the hydrogen as you can see in the balanced equation H₃PO₄ + 3CsOH → Cs₃PO₄ + 3H₂O. Caesium is in group 1 as well so the same principle applies as above. You need three Cs atoms (total charge 3+) bonding with the phosphate ion (charge 3-) so that the charges balance out to zero.

First, the aluminium atoms are balanced. The equation becomes Now, the oxygen atoms must be balanced, there are two oxygen atoms on the reactant side and 3 on the product side. Therefore, there must be 3 O molecules that yield 2 Al atoms. The chemical equation is transformed into → 2Al
How to Balance Chemical Equations 11 Steps (with Pictures)
The equation (Mg) + (HCl) (MgCl2) + (H2) is clearly unbalanced because on one side, there is only 1 hydrogen atom, but on the other side, there are 2 (also unbalanced Chlorine, but they both come from the same compound so this becomes really simple to balance). This equation is easily balanced by placing the coefficient "2" in front of molecule.
