Question

8. Write the balanced chemical equation for the following reaction :
a) Calcium hydroxide reacts with carbon dioxide to give calcium carbonate and water
b) Zinc granules reacts with Silver nitrate to give zinc nitrate and silver.​

Answer 1

Explanation:

a )The question given to us is Calcium hydroxide + Carbon dioxide → Calcium carbonate + Water. The balanced chemical reaction is Ca(OH)2 + CO2 --> CaCO3 + H2O.

b) Maybe...Zn+ 2AgNo3=2Ag + Zn(No3)2
