Question

4. Write one example for each of decomposition reaction carried out with help of

(i) Electricity (ii) Heat (iii) Light
​

Answer 1

Answer:

Decomposition Reaction means the single product breaks down into simpler molecules or products.

(1) H2O (liquid) = H2(gas) + O2(gas).

THIS REACTION IS CARRIED OUT BY ELECTRICITY DECOMPOSITION REACTION.

(2) MgO = Mg + O2. THIS REACTION IS CARRIED OUT BY HEATING DECOMPOSITION REACTION.

(3) AgCl = Ag + Cl2. THIS REACTION IS CARRIED OUT BY SUNLIGHT DECOMPOSITION REACTION.

Explanation:

HOPE IT WILL BE HELPFUL !..

Answer 2

Answer:

electricity : H2O ------ H2 + O2

in heat : CaCo3 --------- CaO +CO2

in light : Agcl --------- Ag +Cl2

Explanation:

the electricity means electrolysis decomposition reaction

the heat means thermal decomposition reaction

the light means photochemical decomposition reaction
