The energy released in a chemical reaction is called chemical energy. The chemical reactions that occur when coal, petrol etc. are burned produce heat and light energy.
Chemical reactions in batteries produce electrical energy. Following are important Chemical energy transformation examples.

Chemical Energy Transformation Examples
Conversion of Chemical energy to other energy
Chemical energy to Electrical energy
In an electric cell (battery), chemical energy is converted into electrical energy.
Chemical energy to Heat energy
Heat is generated by the combustion of coal, kerosene, petrol etc. In this case, chemical energy is converted into heat energy.
Chemical energy to Light energy
Burning magnesium ribbon in the air produces a bright light. In this case, chemical energy is converted into light energy.
Chemical energy to Sound energy
Chemical energy is converted into sound energy in the explosion of crackers, bombs etc.
Chemical energy to Mechanical energy
Chemical energy is converted into mechanical energy by burning coal to run a steam engine.
