Question

Give one example each of displacement , decomposition and combination reaction with explanation

Answer 1

Hope this answers help you

Answer 2

Combination - When a two or more reactant react to form a single product then such reactions are called combination reactions.

egs- Cao + H2O - Ca(OH) 2

Decomposition - when a single reactant react to form a single product then such reactions are called decomposition reactions.

egs- CaCO3 ---> Cao + Co2 in the presence of heat

Displacement - when a highly reactive metal displaces a less reactive metal from it's compound then such reactions are called displacement reaction.

egs- Fe + CuSo4 --> FeSo4 + Cu
