Which clue can be used to identify a chemical reaction as a decomposition reaction? a) the reaction involves oxygen. b) the reaction involves ions. c) the reaction has a single reactant. d)the reaction has a single product.

THe answer is:

C) The reaction has a single reactant.

When the reaction has a single reactant, what will happen most of the time is that that reactant will decompose into several new composes, this will lead to a decomposition and a change in the products.

C) The reaction has a single reactant.
