Question

distinguish between displacement reaction and double displacement reaction identify the displacement and double displacement reaction from the following reactions

Answer 1

Explanation:

If in a Chemical equation, two or more reactants combine to form a single product then it is known as combination reaction.

For e.g, CaO + H2O → Ca(OH)2

If in a chemical reaction a single substance decomposes to form two or more substances then it is known as decomposition reaction.

For e.g. 2AgCl −→−−sunlight 2 Ag + Cl2

If in a chemical equation, more reactive elements displaces a less reactive element from its compound then it is known as displacement reaction.

eg: Zn+CuSO4=ZnSO4+Cu
