Question

Give examples of following.

Answer 1

hey there !!

here is your answer :-

i)Calcium carbonate (limestone or chalk) decomposes into calcium oxide and carbon dioxide when heated. The chemical reaction is as follows:
CaCO3 → CaO + CO2

ii) Water cannot be dissociated easily by supplying but when electricity it can dissociated into its elements.
2H2O→ 2H2 + O2

iii) sunlight causes decomposition of silver chloride into silver and chlorine.
Agcl(s)-------->Ag(s) + Cl₂(g)



hope it helps

Answer 2

(i)sulfide when heated produces copper +sulfur dioxide
(ii) 2H2O(l)→2H2(g)+O2(g) - water decomposes into hydrogen and oxygen in the presence of an electric current
(iii) decomposition of silver chloride
