Question

Write one equation each for decomposition reactions where energy is supplied in the form of heat, light or electricity.

Answer 1

Hii

CaCo3 heat CaO+Co2

2H2O electricity 2H2+O2

Answer 2

We have been given a chemical equation to solve.

We have been given the equation in words and we need to use the appropriate compound symbols and name and complete the balanced equation.

The question given to us is to write one equations each for decomposition reactions where energy is supplied in the form of electricity, heat or light.  

The answers are as follows:  

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

CaCO3--heat->CaO +CO2

2AgCl-----sunlight--->2Ag +Cl2
