Exam Description and Key Details
Format: multiple-choice questions & one best Answer
Access: Purchase through Stuvia and get instant pdf Download
Resources Allowed: Scientific calculator and periodic table
Key Topics
Content: Covers fundamental chemistry topics including: Scientific Method & Measurements:
Sig figs, dimensional analysis, density, physical vs. chemical changes. Atoms & Molecules:
Atomic structure, electron configurations, periodic table trends. Stoichiometry & Reactions:
Balancing equations, mole ratios, molarity, redox, titration. Bonding & Geometry: Lewis
structures, VSEPR theory, polarity. Thermochemistry & Gases: Ideal gas law, enthalpy, state
functions. Study Tips & Strategies Focus on Fundamentals: Review material from the beginning
of the course, as early concepts are heavily tested. Practice Calculations: Focus on
stoichiometry, titration calculations, and unit conversions (\(mL\) to \(L\), \(g\) to
\(mol\)).Redox & Structure: Know how to assign oxidation numbers and predict molecular
geometry/polarity. Exam Strategy: Questions are randomized; manage time wisely (approx. 1.5
minutes per question) and do not leave questions blank.
