Which of the following compounds contains an ionic bondwhich of the following compounds contains an ionic bond?
a. kbr
b. co2
c. nh3
d. ccl4

plz

The correct option is A. KBr

Explanation:

A ionic bond take place between two ions with different charges (cations and anions). In this case K+ (cation) and Br- (anion). The semireactions that gives rise to cation and anion and then to the KBr molecule are:

K⇒ (K+) + 1e-  K oxidizes and release an electron.

Br + 1e- ⇒ Br- Br reduces acepting the electron released.

K + Br + 1e- ⇒ K+Br- + 1 e-

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
