2.MgO + 2HCl =  MgCl₂ + H₂O
3.MgCl₂ + 2AgNO₃ ---> Mg(NO₃)₂+ 2AgCl↓
4.Mg(NO₃)₂ + 2NaOH ---> Mg(OH)₂↓ + 2NaNO₃

Answer 2

Equation for the Reaction: Mg + CO3 -> MgO -> MgCl2 -> Mg(NO3)2 -> Mg(OH)2

To write the balanced chemical equation for the given reaction scheme, we need to determine the formulas and states of the reactants and products involved.

1. Mg + CO3 -> MgO: This reaction involves the combination of magnesium (Mg) with carbonate (CO3) to form magnesium oxide (MgO). The balanced equation for this reaction is:

Mg + CO3 -> MgO 2. MgO -> MgCl2: This reaction involves the reaction of magnesium oxide (MgO) with chlorine (Cl2) to form magnesium chloride (MgCl2). The balanced equation for this reaction is:

MgO + 2Cl2 -> MgCl2 3. MgCl2 -> Mg(NO3)2: This reaction involves the reaction of magnesium chloride (MgCl2) with nitric acid (HNO3) to form magnesium nitrate (Mg(NO3)2). The balanced equation for this reaction is:

MgCl2 + 2HNO3 -> Mg(NO3)2 + 2HCl 4. Mg(NO3)2 -> Mg(OH)2: This reaction involves the reaction of magnesium nitrate (Mg(NO3)2) with sodium hydroxide (NaOH) to form magnesium hydroxide (Mg(OH)2). The balanced equation for this reaction is:

Mg(NO3)2 + 2NaOH -> Mg(OH)2 + 2NaNO3 Therefore, the overall balanced equation for the given reaction scheme is:

Mg + CO3 -> MgO -> MgCl2 -> Mg(NO3)2 -> Mg(OH)2
