Zirconium, $\text{Zr}$, proton number 40, is a metal used to make corrosion-resistant alloys. Zirconium metal is obtained from the oxide $\text{ZrO}_2$ by the reaction sequence shown below. reaction 1: $\text{ZrO}_2 + 2\text{Cl}_2 + 2\text{C} \rightarrow \text{ZrCl}_4 + 2\text{CO}$ reaction 2: $\text{ZrCl}_4 + 2\text{Mg} \rightarrow \text{Zr} + 2\text{MgCl}_2$ Which of these statements about this extraction process are correct?
- A1, 2 and 3
- B1 and 2 only
- C2 and 3 only
- D1 only
