Zinc is a metal whose boiling point is $907\,^{\circ}\text{C}$. Two ways of producing zinc are shown below. Method 1: zinc oxide is heated with carbon at $1000\,^{\circ}\text{C}$, forming zinc. Method 2: zinc oxide is dissolved in dilute sulfuric acid to make zinc sulfate solution, and this is electrolysed at $35\,^{\circ}\text{C}$ to produce zinc. Which statement is correct?
- ACarbon oxidises zinc oxide in method 1.
- BZinc vapour is produced in both methods.
- CZinc is produced at the anode in method 2.
- DZinc compounds are reduced in both methods.
