Which equation shows how lime is formed?
- A$\text{CaCO}_3 \rightarrow \text{CaO} + \text{CO}_2$
- B$\text{CaO} + \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2$
- C$\text{Ca} + 2\text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 + \text{H}_2$
- D$\text{Ca(OH)}_2 + \text{CO}_2 \rightarrow \text{CaCO}_3 + \text{H}_2\text{O}$
