This document contains a chemistry assignment asking students to identify conjugate acids and bases, Bronsted-Lowry acids and bases, and other related concepts in a series of multiple choice questions based on chemical equations. The questions cover topics like identifying the conjugate acid in chemical reactions, determining which compound is the conjugate base in a given reaction, and defining what constitutes a Bronsted-Lowry acid or base versus an Arrhenius acid or base based on whether a compound donates or accepts hydrogen ions.
