1.	Write the balanced equation and identify the type of reaction.1. Magnesium Hydroxide(aq) + Nitric Acid(aq) → Magnesium Nitrate(aq) + Water(l)2. Magnesium(s) + Carbon Monoxide(g) → Magnesium Oxide(s) + Carbon(g)3. Barium Chloride(aq) + Sodium Sulphate(aq) → Barium Sulphate(s) + Sodium Chloride(aq)4. Sodium Nitrate(s) → Sodium Nitrite(s) + Oxygen(g)
Answer» 1. Mg(OH)_2(aq) + 2 HNO_3(aq) → Mg(NO₃)_2(aq) + 2 H₂O_(l) It is both double displacement and neutralisation reaction. 2. Mg_(s) + CO_(g) → MgO_(s) + C_(s) It is a redox reaction in which magnesium is oxidised and carbon monoxide is reduced. 3. BaCl_2(aq) + Na₂SO_4(aq) → BaSO_4(s) ↓ + 2 NaCl_(aq) It is both precipitation and double displacement reaction. 4. 2 NaNO_3(s)→ 2 NaNO_2(s) + O_2(g) It is both endothermic and decomposition reaction.

Answer»

1. Mg(OH)_2(aq) + 2 HNO_3(aq) → Mg(NO₃)_2(aq) + 2 H₂O_(l)

It is both double displacement and neutralisation reaction.

2. Mg_(s) + CO_(g) → MgO_(s) + C_(s)

It is a redox reaction in which magnesium is oxidised and carbon monoxide is reduced.

3. BaCl_2(aq) + Na₂SO_4(aq) → BaSO_4(s) ↓ + 2 NaCl_(aq)

It is both precipitation and double displacement reaction.

4. 2 NaNO_3(s)→ 2 NaNO_2(s) + O_2(g)

It is both endothermic and decomposition reaction.
