What does the TEAS exam’s chemistry section cover?

The TEAS 7 exam’s science section has 44 scored and six unscored questions, while the chemistry section has eight scored questions. Students have 60 minutes to answer 50 questions covering various science topics, including physiology and anatomy. Topics tested in the chemistry section include:

Phase changes

Phase changes are the physical transformation of matter in different states. You should focus on properties of matter like volume, density, and temperature and be familiar with matter’s six-phase changes and the kinetic theory. You should also learn the concept of energy, the heat of fusion & evaporation, and phase diagrams.

States of Matter

You should focus on the properties of matter, three states of matter, and changes of state when studying the states of matter for the chemistry section of your TEAS exam. You should also study the kinetic theory, intermolecular forces, and phase diagrams. These topics help you understand the states of matter and their relationship with the behaviour and properties of substances.

Chemical Bonds

In this topic, you should study the types of chemical bonds, Lewis structures, and electronegativity. You should also study molecular geometry, hybridization, and polarity. Focusing on this information helps you understand chemical bonds and their influence on the behavior and properties of molecules.

Acids and Bases

When studying acids and bases, you should begin with their properties, i.e., their reaction with indicators, conductivity, and pH. You should also study acid-base reactions, pOH & pH, acid-base titrations, acid & base strengths, and buffers. You should study these subsections to understand the behavior and properties of acids & bases and practice with some sample questions to solidify your understanding.

Catalysts and Enzymes

Topics you should study for catalysts and enzymes include enzymes, catalysts, enzyme kinetics, enzyme inhibition, enzyme regulation, and enzyme applications. These topics will make you understand catalysts and enzymes’ importance in chemical and biological processes. You should also attempt some sample questions from the TEAS practice test to familiarize yourself with the questions and how best to answer them.

Periodic Table of Elements

When studying the periodic table of elements, focus on periodic trends, groups and periods, metals, metalloids, and non-metals. You should also concentrate on electron configuration, chemical reactions & the periodic table, and applications. This information helps you understand the periodic table of elements’ importance in various sciences.

Water and Solutions

Topics you should focus on when studying water and solutions include properties of water, concentration units, colligative properties, chemical reactions in solution, buffers, electrolytes, and acids & bases. You should also do some practice questions to determine your grasp of knowledge in the topic.

Reaction Types

Studying for the chemistry subsection of the TEAS exam requires you to be familiar with various chemical reactions like synthesis decomposition and single replacement reactions. You should also be familiar with double replacement, combustion, acid-base, and redox reactions. You should also understand the mole concept and be able to solve chemical reaction-related problems.


Topics you should cover when studying concentration include molarity, i.e., the measure of a solution’s concentration in moles per litre or kilogram. You should be able to make relevant calculations and make solutions for given concentrations. You should also study percent composition, dilution, colligative properties, ideal gas law, and concentration units.
