Question

What happens when ZnCO3 is heated strongly? Give the relevant equation.​

Answer 1

Answer:

When zinc carbonate is heated strongly in the absence of air, it decomposes to form zinc oxide and carbon dioxide. (b) When copper (I) oxide reacts with copper (I) sulphide, it forms copper metal and sulphur dioxide.

Explanation:

Answer 2

Answer:

Zinc carbonate decomposes into zinc oxide and carbon dioxide gas when heated.

Explanation:

Combustion of Zinc carbonate:

• It is a powdery white substance.
• When heated to a high temperature, it begins to turn yellow and degrade, releasing carbon dioxide gas, which produces a white precipitate in limewater.

• Zinc carbonate(s) → Zinc oxide(s) + Carbon dioxide(g)

• ZnCO3 → ZnO + CO2

This reaction is a decomposition reaction of Heating Zinc carbonate.
