Question

explain the combination reaction, decomposition reaction, displacement reaction, double displacement reaction with example​

Answer 1

Answer:

find the attached for the answer

Answer 2

Answer:

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

Example: C + O2 → CO2

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

Example: CaCO3 → CaO + CO2

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

Example: Cl2 + 2NaBr → 2NaCl+ Br2

Double displacement reaction: If in a chemical reaction exchange of ions takes place then it is known as double displacement reaction.

Example: Cu + 2AgNo3 → 2Ag + Cu(NO3)2

Have a nice day ✌️
