Zinc oxide is white but it turns yellow on heating . Explain.

Explanation

To explain why zinc oxide (ZnO) is white but turns yellow upon heating, we can break down the explanation into several steps:

### Step 1: Understanding the Initial State of Zinc Oxide
Zinc oxide is a white solid at room temperature. This is due to its crystal structure and the arrangement of zinc (Zn²⁺) and oxide (O²⁻) ions in the lattice.

**Hint:** Consider the color properties of compounds and how their structures influence their appearance.

### Step 2: Heating Zinc Oxide
