1. $\text{SO}_2 + \text{MgCO}_3 \rightarrow \text{MgSO}_3 + \text{CO}_2$
2. $\text{SO}_2 + \text{H}_2\text{O} + \text{MgCO}_3 \rightarrow \text{MgSO}_3 + \text{H}_2\text{CO}_3$
3. $\text{SO}_2 + \text{H}_2\text{O} + \text{MgCO}_3 \rightarrow \text{MgSO}_3 + \text{CO}_2 + \text{H}_2\text{O}$
4. $2\text{SO}_2 + 2\text{H}_2\text{O} + 2\text{MgCO}_3 \rightarrow 2\text{MgSO}_3 + 2\text{CO}_2$
