This chemistry pre- and post-course test serves as a comprehensive check for understanding at the beginning and end of the school year. Twenty-five multiple choice questions are packed into a full-page document, which is nice for teachers conscientious of the number of pages copied off. Topics covered include: historical discoverers/contributors, periodic trends (Ionization and electronegativity), metric conversions, balancing chemical equations with coefficients, electron configurations, conversion factors, determining molar mass, defining isotopes, stoichiometry, ranking bond strength by classification, hybridization of valence electrons, converting a word expression of a compound to a formula, signs of chemical changes, identifying which ionic compound is balanced by charge, molarity, Brønsted-Lowry acids, classification of chemical reaction, Lewis structure, acid identification from properties, mapping out the correct order in balancing chemical reactions, and Gibb’s free energy equation analysis with enthalpy and entropy. This document can be edited. A two-page color-coated answer key is included.
