Explain Combination reaction with examples.

Explanation:

Combination reactions occur when two or more reactants react together to produce a new product. Synthesis reaction is another name for combination reaction.

Example- Formation of calcium oxide (CaO) by the combination elements calcium (Ca) and oxygen (O₂). 2Ca (s) + O₂ (g) → 2CaO (s)

Hydrogen and chlorine combine to form hydrogen chloride. H₂ (g) + Cl₂ (g) → 2HCl (g)
