General Chemistry placement test
Study Guide (Latest 2026/2027
Update) Questions & Answers |
Grade A | 100% Correct
Description
This General Chemistry placement test assesses high school-
level chemistry knowledge (atoms, bonding, stoichiometry,
periodic table) and basic algebra to determine readiness for
college Chemistry I. It is a multiple-choice exam, allowing a
calculator and periodic table, designed to place students into
either introductory or general chemistry courses.
Exam Content & Topics
Atomic Structure: Atoms, ions, isotopes, electron
configuration, and subatomic particles.
Periodic Table: Trends (electronegativity, atomic radius),
elements, and chemical families.
Compounds & Bonding: Naming/formulas (nomenclature),
Lewis structures, and molecular geometry.
Stoichiometry & Equations: Balancing equations, mole
calculations, molar mass, and limiting reagents.
Reactions & States of Matter: Types of reactions, gas laws
(ideal gas law), solutions, and intermolecular forces.
Mathematics: Scientific notation, significant figures, algebra,
and unit conversions (density, metric prefixes).
