Question

What is combination reaction with examples!

Answer 1

$\huge\mathcal\pink{Combination\:Reaction}$

The reaction in which two or more reactants combine together to form a single product is called combination reaction.

Example :

H2 + O2 → H2O

C + O2 → CO2

Mg + O2 → MgO

Answer 2

Combination Reaction :

When two or more reactants combine to from a single product.

OR

When two or more elements or compounds combine to form a single product.

___________________________

General equation for combination reaction is :

A + B → AB

___________________________

Examples :

• C + O2 → CO2

• H2 + O2 → 2H2O

• 2Mg + O2 → 2MgO

• Fe + S → FeS

• 2SO2 + O2 → 2SO3

• H2 + Cl2 → 2HCl

• Cl2 + PCl → PCl5

• N2 + H2 → 2NH3

• NH3 + HCl → NH4Cl

• CaO + H2O → Ca(OH)2

_____________________________

Combination reactions are usually exothermic because when the bond is formed between the reactants; heat is released.
