Answer 1

1. Na2CO3 + H2SO4 -----> Na2SO4 + H2O + CO3
2Na(+) + CO3(2-) + 2H(+) + SO4(2-) -----> 2Na(+) + SO4(2-) + H2O + CO2
CO3(2-) + 2H(+) ----> H2O + CO2

2. AgNO3 + NaCl ----> AgCl + NaNO3
Ag(+) + NO3(-) + Na(+) + Cl(-) ----> AgCl + Na(+) + NO3(-)
Ag(+) + Cl(-) ----> AgCl

3. MgCl2 + Na2CO3 ------> MgCO3 + 2NaCl
Mg(+) + 2Cl(-) + 2Na(+) + CO3(2-) ----> MgCO3 + 2Na(+) + 2Cl(-)
Mg(+) + CO3(2-) ----> MgCO3

Answer 2

Molecular Equation:

The molecular equation for the given reactions is as follows:

1. Na2CO3 + H2SO4 → Na2SO4 + H2O + CO2 2. AgNO3 + NaCl → AgCl + NaNO3 3. MgCl2 + Na2CO3 → MgCO3 + 2NaCl

Complete Ionic Equation:

The complete ionic equations for the given reactions are as follows:

1. Na^+(aq) + CO3^2-(aq) + 2H^+(aq) + SO4^2-(aq) → 2Na^+(aq) + SO4^2-(aq) + H2O(l) + CO2(g) 2. Ag^+(aq) + NO3^-(aq) + Na^+(aq) + Cl^-(aq) → AgCl(s) + Na^+(aq) + NO3^-(aq) 3. Mg^2+(aq) + 2Cl^-(aq) + 2Na^+(aq) + CO3^2-(aq) → MgCO3(s) + 2Na^+(aq) + 2Cl^-(aq)

Net Ionic Equation:

The net ionic equations for the given reactions are as follows:

1. CO3^2-(aq) + 2H^+(aq) → H2O(l) + CO2(g) 2. Ag^+(aq) + Cl^-(aq) → AgCl(s) 3. Mg^2+(aq) + CO3^2-(aq) → MgCO3(s)

Please note that the above equations are balanced and represent the reactions in their molecular, complete ionic, and net ionic forms.
