Answer 1

Solution :

1. Ionic equation when  $Li_3PO_4$  and $AgNO_3$ are mixed.

  $3 Li^+ (aq) + PO_4^{3-} (aq) + 3Ag^+ (aq) + 3NO_3^-(aq) \rightarrow Ag_3PO_4(s)+3Li^+(aq)+3NO_3^-(aq)$

Net ionic :  $PO_4^{3-}(aq)+3 ag^+(aq) \rightarrow Ag_3PO_4(s)$

2. $K_2SO_4$ and $Na_2CO_3$

  No reaction

3. $K_2SO_4$ and $Na_2CO_3$

  No reaction

4. $Fe(NO_3)_2 \text{ and}\ \ Na_2CO_3$

   $Fe^{2+}(aq)+2NO_3^-(aq)+2Na^+(aq)+CO_3^{2-}(aq) \rightarrow FeCO_3(s) + 2Na^+(aq) + 2NO_3^-(aq)$5. $Fe(NO_3)_2 \text{ and}\ \ Na_2CO_3$

 $Fe^{2+}(aq)+2NO_3^-(aq)+2Na^+(aq)+CO_3^{2-}(aq) \rightarrow FeCO_3(s) + 2Na^+(aq) + 2NO_3^-(aq)$6. $BaCl_2 \text{ and}\ \ KOH$

$Ba^{+2}(aq)+2Cl^-(aq)+2K^+(aq)+2OH^-(aq) \rightarrow Ba(OH)_2(s) + 2K^+(aq) + 2Cl^-(aq)$

7. $BaCl_2 \text{ and}\ \ KOH$

$Ba^{+2}(aq)+2Cl^-(aq)+2K^+(aq)+2OH^-(aq) \rightarrow Ba(OH)_2(s) + 2K^+(aq) + 2Cl^-(aq)$
