Zinc carbonate is converted into __________ by calcination. (ZnO/ZnS)

Explanation

To solve the question, we need to understand the process of calcination and how it applies to zinc carbonate.

### Step-by-Step Solution:

1. **Identify the substance**: The question states that we have zinc carbonate, which is chemically represented as ZnCO₃.

2. **Understand calcination**: Calcination is a thermal treatment process in which a carbonate ore is heated in the absence of air. This process typically converts the carbonate into its corresponding metal oxide and releases carbon dioxide gas.
