1. A double replacement reaction can be best described as a reaction in which (1 point) A.) a substitution takes place.

B.) two atoms of a compound are lost.

C.) ions are exchanged between two compounds.

D.) electrons are exchanged between two atoms.

C.) ions are exchanged between two compounds.

Explanation:

In a double replacement reaction, ions are exchanged between two compounds.

This reaction type involves an actual exchange of partners to form new compounds.

For example:

                 AB + CD  →  AD  + CB

This reaction involves two ionic compounds exchanging partners.
