Balance the following equations :

(i) Na + $O_{2}$ $⟶$ $N a_{2} O$

(ii) $H_{2} O_{2}$ + $⟶$ $H_{2} O + O_{2}$

(iii) $M g (O H)_{2}$ +HCl $⟶$ $M g C l_{2}$ + $H_{2} O$

(iv) Fe + $O_{2}$ $⟶$ $F e_{2} O_{3}$

(v) $A l (O H)_{3}$ $⟶$ $A l_{2} O_{3}$ + $H_{2} O$

(vi) $N H_{3}$ + CuO $⟶$ Cu + $N_{2}$ + $H_{2} O$

(vii) $A l_{2} (S O_{4})_{3}$ + NaOH $⟶$ $A l (O H)_{3}$ + $N a_{2} S O_{4}$

(viii) $H N O_{3}$ + $C a (O H)_{2}$ $⟶$ $C a (N O_{3})_{2}$ + $H_{2} O$

(ix) NaOH + $H_{2} S O_{4}$ $⟶$ $N a_{2} S O_{4}$ + $H_{2} O$

(x) $B a C l_{2}$ + $H_{2} S O_{4}$ $⟶$ $B a_{2} S O_{4}$ + $H C l$
