Question

write balanced equation one each of decomposition using electricity and sunlight?
​

Answer 1

Answer:

(1.) Decomposition on heating

Calcium carbonate when heated gives quicklime (CaO) and carbon dioxide

CaCO

3

→CaO+CO

2

(2.) Decomposition by light

Silver chloride decomposes to silver and chlorine in presence of sunlight

2AgCl→2Ag+Cl

2

(3). Decomposition by electricity

Water on electrolysis gives hydrogen and oxygen

2H

2

O→2H

2

+O

2

Answer 2

Answer:

Explanation:

electrolytic decomposition equation :

2H₂O(l)  ⟶ 2H₂ (g)+O₂ (g)

photo decomposition equation :

2H₂ O₂ ⟶ 2H₂ O+O2₂
