Combination reaction

Wikipedia, the free encyclopedia - Cite This Source

A Combination Reaction or a Synthesis Reaction is a general category of a chemical reaction (the term usually refers to an inorganic chemical reaction), in which two or more reagents are chemically bonded together to produce a single product.

For example, the addition of sulfur and iron to form iron sulfide is a combination reaction.

A combination reaction can be of three types:
a) Between 2 elements
b) Between 2 compounds
c) Between an element and a compound

Examples:
a) 2Mg+O₂ → 2MgO
b) O+H₂O → H₂O₂
c) 2C(s) +2O₂(g) → 2CO₂ (g)
