This Is the Foundation Course
Everything in organic chemistry and biochemistry builds on what you learn in CHM-113. Don’t start your science career behind.
What Is CHM-113 at GCU?
CHM-113 (General Chemistry I-Lecture) is the first course in GCU’s two-semester general chemistry sequence for science majors. It’s a 3-credit lecture course that runs alongside CHM-113L, a separate 1-credit hands-on laboratory course. Together they form the 4-credit foundation required for pre-med, nursing BSN programs, biology, chemistry, and other STEM majors.
The course is delivered through Mastering Chemistry—Pearson’s adaptive homework platform—using the textbook Chemistry: The Central Science (15th ed.) by Brown, LeMay, and Bursten. CHM-113 covers the quantitative foundations: dimensional analysis, atomic structure, stoichiometry, thermochemistry, electronic structure, chemical bonding, and intermolecular forces. These concepts become the vocabulary for everything that follows in organic chemistry and biochemistry.

The 7-Week CHM-113 Rhythm
Here’s how the course typically unfolds—and where students crash:
Week 1: Matter & Measurement
Classification of matter, states of matter, physical vs. chemical changes, dimensional analysis, significant figures, atomic theory. Mastering Chemistry homework feels manageable. Students underestimate what’s coming.
Week 2: THE WALL — Stoichiometry
Stoichiometry and aqueous reactions. Mole conversions, balancing equations, limiting reactants, percent yield, solution concentration, molarity. This week separates students who succeed from those who struggle. Quiz 1.
Week 3: Thermochemistry
Energy, enthalpy, heat capacity, calorimetry, Hess’s Law. Math-heavy calculations build on stoichiometry. Students who struggled in Week 2 fall further behind.
Week 4: Electronic Structure
Electromagnetic radiation, quantum numbers, electron configurations, periodic trends. Quiz 2. Midterm exam covering Weeks 1-3. Conceptual shift from calculations to theory.
Week 5: Chemical Bonding
Lewis structures, formal charge, bond enthalpy, VSEPR theory, molecular geometry, polarity. Drawing structures and predicting shapes—a completely different skill set from earlier weeks.
Week 6: Advanced Bonding
Orbital hybridization, sigma and pi bonds, molecular orbital theory. Quiz 3 and Quiz 4. Abstract concepts that require visualizing electron behavior in 3D.
Week 7: Intermolecular Forces + Final
States of matter, phase diagrams, intermolecular forces (London dispersion, dipole-dipole, hydrogen bonding). Comprehensive final exam covering all 7 weeks.
Where CHM-113 Students Get Stuck
Stoichiometry (Week 2 — The Foundation)
Stoichiometry is the quantitative heart of chemistry. Every calculation in general chemistry builds on your ability to convert between grams, moles, and particles—then use balanced equations to determine how much product forms from given reactants. Miss this, and the rest of the course becomes impossible.
The mole conversion roadmap:
Particles → (÷ Avogadro’s number) → Moles → (× molar mass) → Grams
Common errors: Using atomic mass instead of molecular mass. Forgetting to balance equations before calculating. Mixing up limiting and excess reactants. Not converting properly when given solution molarity. Mastering Chemistry requires exact answers with proper significant figures.
Thermochemistry Calculations
Thermochemistry combines stoichiometry with energy calculations. You’re not just finding how much product forms—you’re calculating how much heat is released or absorbed. Hess’s Law problems require manipulating multiple equations and their enthalpies to find the overall ΔH.
Critical formulas:
- q = mcΔT — heat = mass × specific heat × temperature change
- q = nΔH — heat = moles × enthalpy change
- ΔH°rxn = Σ ΔH°f(products) − Σ ΔH°f(reactants) — using standard enthalpies of formation
Electron Configurations
Writing electron configurations requires memorizing the aufbau filling order, understanding Pauli exclusion and Hund’s rule, and recognizing exceptions (chromium, copper). Condensed configurations using noble gas cores add another layer. Students who memorize without understanding get lost on exam problems asking them to identify elements from configurations or predict properties.
Filling order: 1s → 2s → 2p → 3s → 3p → 4s → 3d → 4p → 5s → 4d → 5p → 6s → 4f → 5d → 6p → 7s → 5f → 6d → 7p
Lewis Structures & VSEPR
Drawing Lewis structures requires counting valence electrons, distributing them correctly, and minimizing formal charges. Then VSEPR theory predicts 3D geometry based on electron domains. Students must visualize molecules in three dimensions while accounting for lone pairs that affect bond angles but aren’t visible in simple drawings.
The VSEPR decision tree: Count electron domains around central atom → Determine electron geometry → Identify lone pairs → Determine molecular geometry → Predict polarity.
Mastering Chemistry: The Platform
Mastering Chemistry is Pearson’s adaptive homework system integrated with the Chemistry: The Central Science textbook. Unlike ALEKS (used in CHM-101), Mastering Chemistry follows a more traditional assignment structure—but it has its own challenges.
How Mastering Chemistry Works
- Weekly homework assignments — Problems tied to each chapter, due on specific dates
- Practice quizzes — Ungraded or low-stakes practice before major assessments
- Hints and feedback — Multi-step hints available (sometimes with point deductions)
- Multiple attempts — Some problems allow 2-3 attempts with partial credit
- Randomized values — Same problem structure but different numbers for each student
Common Mastering Chemistry Frustrations
“The answer was right but it wanted different significant figures…”
“I used the hint and now I can only get partial credit…”
“The interface for drawing Lewis structures is impossible…”
— Common student complaints
Format precision matters: Mastering Chemistry requires exact formatting—correct significant figures, proper scientific notation, specific units. An answer that’s mathematically correct but formatted wrong loses points.
CHM-113L: The Lab Component
CHM-113L is a separate 1-credit co-requisite course with hands-on laboratory work. Unlike CHM-101’s virtual Pivot Interactives labs, CHM-113L involves actual in-person experiments with physical lab reports.
Typical CHM-113L experiments include:
- Density determination — Measuring mass and volume to calculate density of solids and liquids
- Classification of chemical reactions — Observing synthesis, decomposition, single/double replacement
- Gas laws — Experimental verification of Boyle’s and Charles’s laws
- Calorimetry — Measuring enthalpy change using coffee cup calorimeters
- Empirical formula determination — Finding formulas from experimental mass data
What we handle:
- Pre-lab assignments — Calculations and preparation questions due before lab
- Lab reports — Introduction, procedure, data tables, calculations, discussion, conclusion
- Post-lab questions — Conceptual questions connecting lab results to lecture material
- Data analysis — Proper significant figures, percent error calculations, graphing
All written work is 100% original and follows scientific writing conventions expected in STEM courses.
