SAT II Chemistry
The SAT II Chemistry test is one of the most popular subject tests that students take as part of their college entrance exams. Most high school students take the Introductory Chemistry class as one of their mandatory science classes before graduation. Students are highly recommended to take the Introductory Chemistry class or AP chemistry class to prepare this subject test. The SATII Chemistry test consists of 85 multiple choice questions and "relationship analysis" questions. The score range is 200 to 800. No calculator is allowed. Therefore, only simple arithmetic calculation will be on the test. The average score for the Chemistry Subject test in 2006 was around 620. Thus, scores over 750 will reflect positively on students' academic achievements for their college entrance. An understanding of principles and concepts of introductory chemistry is the key to a high score on this subject test. Our on-line tutoring program covers all the areas of study required for this test. It is specifically designed to help students learn and practice key concepts to prepare for the SAT II chemistry test efficiently.
The program will cover the following topics:
A. Atomic Structure -Atomic structure, quantum numbers, electron configurations, and electron configurations.
B. Molecular Structure - Lewis structures, molecular shape, and polarity.
C. Bonding -The three types of bonds (ionic, covalent, and metallic bonds) and intermolecular forces (hydrogen bonding, dipole-dipole forces, and London dispersion forces)
D. Gases -Gas laws and the kinetic molecular theory
E. Liquids and Solids -Types of solids and phase diagrams
F. Solutions -Molarity, molality, mole fraction, normality and colligative properties
2. Types of Reaction:
A. Acids and Bases
-Strong and weak acids and bases, pH, titrations, and buffer.
- Oxidation number, half reactions and balancing ions.
- Solubility properties and common ion effect
- Mole concepts (Avogadro's number), balancing of equations, limiting reactants, empirical and molecular formulas, and percent yield.
4. Equilibrium and Reaction Rate:
- The expression of equilibrium constants and Le Chatelier's principle.
B. Rates of Reactions
- Calculation of reaction rates and activation energy.
- Concepts of enthalpy, entropy, and Gibb's free energy.
6. Properties of Elements and Compounds:
- Several topics including organic chemistry, nomenclature of ions and compounds, and prediction of products of chemical reactions.
-Lab procedures, calculation, and data analysis using proper lab equipment.
