PRAXIS II Chemistry: Content Knowledge Exam (5245)

Do you want to teach chemistry in secondary schools? The Praxis II Chemistry: Content Knowledge Exam can give you the ability to teach chemistry in around 40 states and United States territories. The Praxis II Chemistry: Content Knowledge Exam, 5245, consists of 125 selected-response questions. Each tester will have two and a half hours to answer all of the questions, and the test is administered through a testing center.

The test questions and test construction reflect the National Science Education Standards and the National Science Teacher Association standards. The fundamental concepts and processes are test by using questions that focus on conceptual understanding, critical thinking, and scientific problem solving. Seven different content categories are tested, and each category consists of approximately 15-20 questions. The only exception is that the chemical reactions section has a slightly larger percentage with approximately 25 questions. The periodic table is available as a tool to help along with a table of basic conversions. A calculator will not be necessary.

The Praxis II Chemistry: Content Knowledge Exam measures the knowledge and skills of basic principles of matter and energy as well as thermodynamics. For this first section, testers should be prepared for questions on the organization of matter, particulate structure of matter, differences between chemical and physical properties and physical changes, conservation of energy and matter, and different forms of energy. This section will also include questions on temperature, thermal energy, heat capacity, temperature scales, units of energy, phase transitions, kinetic molecular theory, ideal gas laws, energetics of chemical reactions, and phase changes.

The second tested section, atomics and nuclear structure, focuses on electron configuration of elements, radioactivity, and electronic absorption. The chemical composition section tests names and chemical formulas of compounds, common bond properties and types, identifying molecules, and molecular geometry. The chemical reactions section tests knowledge of the periodic table, balancing chemical equations, Stoichiometric calculations, chemical kinetics, and oxidation-reduction reactions.

The solutions and solubility section looks at colligative properties and equilibrium in ionic solutions. In this section, identification of acids and bases and the equilibrium in acid-base chemistry is assessed. The processes involved in scientific inquiry come up next, along with experimental design and the nature of scientific knowledge. Finally, testers should demonstrate the ability to collect, evaluation, manipulate, interpret, and report data.

This is just a snapshot of what will be tested in each of the Praxis II Chemistry: Content Knowledge Exam sections. However, luckily for you, each section will be covered in detail in the Praxis II Chemistry: Content Knowledge Exam Practice Test and the Praxis II Praxis II Chemistry: Content Knowledge Exam Practice Questions. You will be more prepared for the Praxis II Chemistry: Content Knowledge Exam by practicing with the Practice Test and Practice Questions. By putting in a little extra study time, you will ensure success on the Praxis II Chemistry: Content Knowledge Exam and be one step closer to teaching chemistry around the United States.

It should be noted that calculators are not permitted during the Chemistry: Content Knowledge (0241) exam.
