Question

Name various type of energy for decomposition reaction

Answer 1

Answer:

light energy

electrical energy

heat energy

catalyst

Answer 2

(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

$2H_{2}</p><p>O→2H_{2} +O _{2}$
