Question

what kind of reaction is symbolized by ab + c → cb + a?
a. double replacement
b. decomposition
c. single replacement
d. synthesis

Explanation:

In a single - replacement reaction, one element replaces another element in a compound. Here, element C replaces element A in compound AB to form a new compound CB and free element A. In double - replacement reactions, two compounds exchange ions. Decomposition reactions involve a single compound breaking down into simpler substances. Synthesis reactions involve combining two or more substances to form a single compound.

Answer:

C. Single replacement
