Single-replacement reactions can take place with nonmetals. For this question, assume that A and C are nonmetals and B is a metal. Which general equation shows one nonmetal replacing another nonmetal in a compound?

The general equation for showing one nonmetal replacing another nonmetal in a compound would be BA + C = BC + A. This is an example of a single-replacement reaction where one of the reactant replaces one atom in a compound producing another substance having different properties.
