Balance the following chemical equations: (i) Mg(OH) 2 + HCl → MgCl 2 + H 2 O (ii) N 2 +H 2 → NH 3 (iii) P 4 +O 2 → P 2 O 5

Question

Philoid · Accepted Answer

(i) Mg(OH)₂ + 2HCl → MgCl₂ +2H₂O

(ii) N₂ +3H₂→ 2NH₃

(iii) P₄+5O₂ → 2P₂O₅

Reason: Number of atoms on both sides of the equation should be equal for balanced equations.
