Answer 1

1).

Molecular reaction : Here we write overall balanced reaction.

2Na₃PO₄ (aq) + 3BaCl­₂ (aq) --- >6 NaCl (aq) + Ba₃(PO₄)₂ (s)

2). Full Ionic reaction : We split aqueous terms into ions.

6Na⁺ (aq) + 2 PO₄^3- (aq) + 3Ba²⁺ (aq) + 6 Cl^- (aq) --- >6Na⁺ (aq) +6 Cl^- (aq) + Ba₃(PO₄)₂ (s)

3) Net ionic reaction :

Spectator ions (same) from both side of the equation are cancelled.

Let show the net ionic equation

2 PO₄^3- (aq) + 3Ba²⁺ (aq) --- > Ba₃(PO₄)₂ (s)

2). Molecular reaction:

2FeCl₃ (aq) + 3CuSO₄(aq) --- > Fe₂(SO₄)₃ (aq) +3 CuCl2(aq)

Full ionic equation

2Fe³⁺ (aq) +3 Cl^- (aq) + 3Cu²⁺(aq) + 3 SO₄^2- (aq) -- > 2Fe³⁺ (aq) +3 Cl^- (aq) + 3Cu²⁺(aq) 3 SO₄^2- (aq)

Net ionic equation

All of the above ions are spectator ions so no net reaction
