Question

write decomposition and combination reactions with examples​

Answer 1

2 H 2(g) + O 2(g) → 2 H 2O(ℓ)

2 NaHCO 3(s) → Na 2CO 3(s) + CO 2(g) + H 2O(ℓ)

CH 4 + 2 O 2 → CO 2 + 2 H 2O.

2 C 12H 26 + 37 O 2 → 24 CO 2 + 26 H 2O.

C 2H 5OH + 3 O 2 → 2 CO 2 + 3 H 2O.

2 C 2H 2N 2O 4 + O 2 → 4 CO 2 + 2 H 2O + 2 N 2

Answer 2

A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen

Combination reactions can be between two different compounds like in the above reaction where magnesium oxide combines with carbon dioxide to give magnesium carbonate. ... A simple
