ii) Simple displacement
iii) Precipitation
iv) Combination
v) Neutralization
List B:
1) Formation of ammonia gas from nitrogen and hydrogen gas.
2) An acid reacts with a base to give a salt and water
3) Iron reacts with dilute hydrochloric acid
4) Zinc carbonate is heated to give zinc oxide and carbon dioxide gas
5) Barium chloride solution reacts with dilute sulphuric acid to give barium sulphate and hydrogen chloride​

Answer 1

Answer:

i) Decomposition  - Zinc carbonate is heated to give zinc oxide and carbon dioxide gas

ii) Simple displacement   - Iron reacts with dilute hydrochloric acid

iii) Precipitation  -Barium chloride solution reacts with dilute sulphuric acid to give barium sulphate and hydrogen chloride​

iv) Combination   -Formation of ammonia gas from nitrogen and hydrogen gas.

v) Neutralization  - An acid reacts with a base to give a salt and water
