Answer 1

$\text{H}_3\text{PO}_4 + 3\text{KOH} \longrightarrow \text{K}_3 \text{PO}_4 +3\text{H}_2 \text{O}\\\\10\text{Na} +2 \text{NaNO}_3 \longrightarrow 6\text{Na}_2 \text{O} + \text{N}_2\\\\\ 2\text{H}_3 \text{PO}_4 + 3\text{Mg(OH)}_2 \longrightarrow \text{Mg}_3(\text{PO}_4)_2+6\text{H}_2 \text{O}\\\\2\text{Al(OH)}_3 + 3\text{H}_2 \text{CO}_3 \longrightarrow \text{Al}_2(\text{CO}_3)_3 + 6\text{H}_2 \text{O} \\\\2\text{C}_6\text{H}_6+15\text{O}_2 \longrightarrow 12\text{CO}_2 +6\text{H}_2 \text{O}$

$\text{Pb(OH)}_2 +2\text{HCl} \longrightarrow \text{PbCl}_2 +2 \text{H}_2 \text{O}$

$2\text{Mn} + 6\text{HI} \longrightarrow 3 \text{H}_2+2\text{MnI}_3$
