Chemistry is the MCAT subject that is most often tested. The person taking the test should know the basics of the subject, but they should also be able to use the information in real life. This chapter will be mostly about how to answer the chemistry test questions. The answers to the questions will be given in the form of multiple-choice questions (MCQs) to make them easier to understand.
Chapter 5 is a review of the MCAT Chemistry subject. Chemical Equations, Stoichiometry, Acids and Bases, Thermochemistry, and Electrochemistry are all important ideas that the test-taker must understand in order to do well. This chapter will go over the main ideas of each of these three topics and give solved examples to help the test-taker understand the material better.
It’s important to understand these ideas because the test will cover them. I’ve given a list of examples from past tests that have already been solved to help the person taking the test understand the material better.
