Question

a chemical reaction that has the general formula of ab + c → cb + a is best classified as a reaction.

Explanation:

In a single - replacement (also called displacement) reaction, one element replaces another element in a compound. The general formula for a single - replacement reaction is \(A + BC
ightarrow AC + B\) (or in the form given in the problem \(AB + C
ightarrow CB+A\)). Here, element \(C\) replaces element \(A\) in the compound \(AB\) to form the new compound \(CB\) and the element \(A\).

Answer:

single - replacement (or displacement)
