Answer 2

Mg + CaCO3 = MgCO3+Ca

Mg + ZnCL2   = MgCl2+Zn

Mg + Ca(OH)2   = Mg(OH)2+Ca

Mg +  BaSO4  = MgSO4+Ba

Answer 3

Ionic Equations for the Given Reaction Chain

To solve the given reaction chain and determine the products, we need to write the ionic equations for each step. Let's break down the reaction chain and solve it step by step:

1. MgCO3 → Mg^2+ + CO3^2- 2. MgCl2 → Mg^2+ + 2Cl^- 3. Mg(OH)2 → Mg^2+ + 2OH^- 4. MgSO4 → Mg^2+ + SO4^2-

Now, let's substitute the products of each reaction into the next equation:

1. Mg^2+ + CO3^2- + MgCl2 → MgCO3 + 2Cl^- 2. Mg^2+ + 2Cl^- + Mg(OH)2 → MgCl2 + 2OH^- 3. Mg^2+ + 2OH^- + MgSO4 → Mg(OH)2 + SO4^2-

Finally, let's substitute the products of each reaction into the next equation:

1. MgCO3 + 2Cl^- + Mg(OH)2 → MgCl2 + CO3^2- + 2OH^- 2. MgCl2 + 2OH^- + MgSO4 → Mg(OH)2 + 2Cl^- + SO4^2-

Solving the Reaction Chain

Now, let's solve the reaction chain by substituting the given compounds into the equations:

1. MgCO3 + 2Cl^- + Mg(OH)2 → MgCl2 + CO3^2- + 2OH^- - In this equation, we have MgCO3, MgCl2, and Mg(OH)2 as the reactants. - The products are MgCl2, CO3^2-, and 2OH^-. - Therefore, the equation is balanced.

2. MgCl2 + 2OH^- + MgSO4 → Mg(OH)2 + 2Cl^- + SO4^2- - In this equation, we have MgCl2, Mg(OH)2, and MgSO4 as the reactants. - The products are Mg(OH)2, 2Cl^-, and SO4^2-. - Therefore, the equation is balanced.

Conclusion

The balanced ionic equations for the given reaction chain are:

1. MgCO3 + 2Cl^- + Mg(OH)2 → MgCl2 + CO3^2- + 2OH^- 2. MgCl2 + 2OH^- + MgSO4 → Mg(OH)2 + 2Cl^- + SO4^2-
