Chemistry is organized by content themes and further broken down into topics. The content themes represent a unit of study and are shown below:
Themes
- Introduction to Chemistry
- Matter and Atoms
- The Periodic Table
- The Electronic Structure of Atoms
- Chemical Bonding and Molecular Representations
- Stoichiometry and Chemical Reactions
- Intermolecular Forces of Liquids and Solids
- Gases
- Physical Properties of Solutions
- Acids and Bases
- Chemical, Acid-Base, and Solubility Equilibria
- Energy
- Redox Reactions and Electrochemistry
- Nuclear Chemistry
Topics
Each theme contains a range of specific topics. For example, here are some topics within The Periodic Table.
- Periodic Table Development and Classification of Elements
- Periodic Trends
Subtopics
Each topic contains two subtopics that categorize questions into their designated skill level types. The two subtopics used in Chemistry are below:
Assessments
In addition to our practice guide, Chemistry includes diagnostic exams, topic quizzes, and simulations that include questions unique from those on our practice guide. Diagnostic exams are designed as "pre-tests" assessing prior knowledge and skill, while topic quizzes are short review assessments over major ideas found within the themes. Simulations are virtual labs that have accompanying auto-graded and short-response questions.
Free Response Questions
Chemistry includes free-response questions in the form of classroom sample tasks. Classroom sample tasks are written response assignments that are rooted in real-world scenarios and assess both scientific content and skill.
