Give the formula of the conjugate base of each of the following. (Type your answer using the format CO2 for CO2, (NH4)2CO3 for (NH4)2CO3, [NH4]+ for NH4+, and [Ni(CN)4]2- for Ni(CN)42-.) (a) NH3

a) [NH2]-,

b) [O]2-

c) [Cl]-

Explanation:

The conjugate base is the base member (X⁻) of a weak acid (HX). In other words, the conjugate base is the remaining substance due to the proton loss in the acid HX.

a) For NH₃, (HX; X: NH₂⁻), conjugate base is NH₂⁻. In the format, [NH2]-.

b) For OH⁻, (HX; X: O²⁻), conjugate base is O²⁻. In the format, [O]2-.

c) For HCl, (HX; X: Cl⁻), conjugate base is Cl⁻. In the format, [Cl]-.

i think that the answer is c
