Question

Give an example of the decomposition reaction. Describe an activity to illustrate such a reaction by heating

Answer 1

Reaction of decomposition:

Decomposition reaction is a type of reaction in which the compound breaks into two or more products.

Examples of decomposition reaction is:

• Decomposition of baking soda.
• Decomposition of hydrogen peroxide.
• Decomposition of carbonic acid.

When decomposition takes place through heat energy, it is called as thermal decomposition.

Illustration for decomposition by heating process:

• When calcium carbonate is heated, carbon dioxide is evaporated with calcium oxide.
• When water is heated, it produces monatomic oxygen and hydrogen.

Answer 2

HELLO MATE, HERE IS YOUR ANSWER.....Reaction:when lead nitrate is heated in a test tube, it forms lead oxide, nitrogen di oxide, oxygen.

Activity: heat this test tube for a while.

Conclusion: decomposition of lead nitrate is a thermal decomposition reaction.

THANKYOU....
