(i) Calcium carbonate reacts with dilute hydrochloric acid.
(ii) Dilute Sulphuric acid is poured over sodium sulphite.
(iii) Zinc nitrate is heated.
(iv) Carbon dioxide is passed through sodium hydroxide solution

Answer 1

Answer:

Caco3+HCl= cacl2+H20+co2

Answer 2

Answer:

1) CaCO3+HCL->CaCL2+CO2+H2O

2)H2S04 + Na2SO3->Na2SO4 +H2O+SO3

3)2ZnO + 4NO2 + O

4)2NaOH+CO2=Na2CO3+H2O

HOPE THIS IS CORRECT AND HELPFUL TO U.
