A combination reaction is a chemical reaction in which two or more substances combine to form a single product.

In simple words, a combination reaction happens when two or more reactants come together to form one product. The general equation is:

A + B → AB

Examples of Combination Reactions

Formation of Water: Hydrogen reacts with oxygen to form water.
2H₂ + O₂ → 2H₂O
Formation of Calcium Oxide: Calcium reacts with oxygen to form quicklime.
2Ca + O₂ → 2CaO
Formation of Ammonia: Nitrogen reacts with hydrogen.
N₂ + 3H₂ → 2NH₃
Burning of Carbon: Carbon reacts with oxygen to form carbon dioxide.
C + O₂ → CO₂
