Question

write one equation each for the decomposition reactions where energy is supplied in the form of heat, light or electricity. OR Decomposition reactions require energy either in the form of heat or light or electricity for breaking down the reactants. Write one equation each for decomposition reactions where energy is supplied in the form of heat, light and electricity

Answer 1

Answer:

Heat Decomposition: CaCo3 --> CaO+Co2

Explanation:

By adding heat to Calcium Carbonate the by product can produce Calcium Oxide and Carbon Dioxide.

Answer:

Light Decomposition: 2AgCl -->  2Ag(s)+Cl2(g)

Explanation:

By exposing light to silver chloride it produces silver and chlorine

Answer:

Electric Decomposition: 2H20 -->  2H2(g)+O2(g)

Explanation:

By conducting electricity to water it decomposes hydrogen and oxygen (electrolysis)
