Question

What is a combination reaction?

Answer 1

Combination reaction: A combination reaction is a type of chemical reaction in which two or more atoms, molecules, or compounds are combined together to form a new compound.

Example: A combination of Carbon and oxygen leads to the formation of carbon dioxide.

Balanced chemical reaction: $\underset{\mathrm{Carbon}}{\mathrm{C}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}$
