Question
_____________ (+ heat) → zinc oxide + carbon dioxide
- Zinc carbonate
- Zinc oxide
- Zinc metal
- Zinc hydrogen carbonate
Hint:
A decomposition reaction can be defined as a chemical reaction in which a single reactant breaks down into two or more products.
The correct answer is: Zinc carbonate
Zinc carbonate (+ heat) → zinc oxide + carbon dioxide
- When zinc carbonate is heated, it will decompose to produce zinc oxide (ZnO), which is the metal oxide, and carbon dioxide (CO2) gas.
- Here the single compound- zinc carbonate break down into two components- zinc oxide (ZnO), and carbon dioxide.
- Hence called as decomposition reaction.
