Question

design an activity to demonstrate the decomposition reaction.​

Answer 1

Example of a decomposition reaction: When lead nitrate is heated in a test tube, it forms lead oxide, nitrogen dioxide and oxygen. Activity: Take lead nitrate powder which is white incolour in a test tube. Heat this test tube over a flame. Observation: Brown fumes are evolved and brownish residue is left in the test tube. Conclusion: Decomposition of lead nitrate is a thermal decomposition reaction.
