Answer:

In a composition reaction, two or more reactants -- often but not always elements -- combine to form a more complex compound.

Explanation:

An example of a composition reaction is burning coal, which is mostly carbon:

#"C"+"O"_2->"CO"_2#

Composition reactions can also involve simpler compounds combining to make more complex ones. For example, the carbon dioxide produced above could be captured by magnesium oxide:

#"MgO"+"CO"_2->"MgCO"_3#
