Question

6. Give two uses of quick lime 7. What is electrolytic decomposition? 8. Identify the following type of reactions:- ( Na2SO4 + BaCl2→BaSO4 + 2NaCl ( CaCO3 → CaO + CO2
( Fe + CuSO4 → FeSO4 + Cu
( Pb(NO)3 +2 KI→PbI2 +2KNO3
( CaO +H2O →Ca (OH)2

if you answer correct I will mark as brainlist​

Answer 1

Answer:

6. Quick lime is used for production of iron and steel, paper and pulp. It is also used for treatment of water and flue gases in mining industry.

7. when an electric current is passed through the aqueous solution of a compound, it results into electrolytic decomposition.

8. a) Na2SO4 + BaCl2→BaSO4 + 2NaCl

‹- Double displacement reaction

b) CaCO3 → CaO + CO2

‹- decomposition reaction

c) Fe + CuSO4 → FeSO4 + Cu

‹- displacement reaction

d) ( Pb(NO)3 +2 KI→PbI2 +2KNO3

‹- double decomposition reaction

e) CaO +H2O →Ca (OH)2

‹- Combination reaction
