Praxis II Chemistry Content Knowledge 0245 Exam

Some candidates for a teaching license in secondary level chemistry instruction must pass the PRAXIS II Chemistry Content Knowledge Exam (0245). If that’s true in your state, be sure to review these general topics before taking the test:

• atomic and nuclear structure (10 questions);
• history and nature of science, and science, technology and social perspectives (11 questions);
• mathematics, data management, measurement, and laboratory procedures and safety (14 questions);
• matter and energy, heat, and thermodynamics and thermo chemistry (16 questions);
• nomenclature, chemical bonding, the mole, and geometry (14 questions);
• periodicity and reactivity, biochemistry, chemical reactions, and organic chemistry (23 questions); and
• solutions and solubility, and acid/base chemistry (12 questions).

When studying for the Praxis II Chemistry Content Knowledge Exam (0245), review these respective aspects of the above topics:

• atomic structure, electron arrangement, and nuclear reactions;
• the scientific process, experiment formulation, science history, and the link between society and science;
• measuring and interpreting data, proper laboratory use of substances and tools, safety practices for chemical mixtures, and chemical materials disposal;
• types, organization, features, and preservation of matter and/or energy; temperature measurements; thermal energy’s effect on matter; thermal energy conduction; the laws of molecular kinetics, gases, and thermodynamics; and thermo-chemistry;
• the naming system of molecular and ionic compounds, the naming of organic compounds among functional groups, the mole as a component of chemical composition, chemical formulas, chemical bonding, and molecular biology;
• patterns of periodicity in electron configurations, periodicity with types of bonds, chemical reactions, atom features, organic chemistry and biological chemistry; and
• solutions types and vocabulary, effects of solubility, chemical concentration, and the chemistry of acids and bases.

The Praxis II Chemistry Content Knowledge Exam (0245) contains 100 multiple choice. It costs $80 and lasts two hours.
