Question

write three equations for decomposition reaction where energy is supplied in the form of heat , light and electricity?​

Answer 1

Answer:

Decomposition reaction requiring heat is known as thermal decomposition , CaCO3--------->CaO + CO2. Decomposition reaction requiring light is known as photo chemical decomposition reaction , 2AgCl-------2Ag + Cl2.

Answer 2

Answer:

your answer is here !

Explanation:

HI there !!

1)

When electricity is passed through water , it leads to the formation of H₂ and O₂.

electricity

2H₂O -----------------------> 2H₂ + O₂

2)

When Calcium carbonate is heated it form Calcium oxide [ quick lime ] and water

heat

CaCO₃ ----------------> CaO + CO₂

3)

When silver chloride is kept in sunlight for some time ,

it decomposes and forms silver and chlorine gas.

sunlight

2AgCl [s] -------------------> 2Ag [s] + Cl₂ [g]
