Study.com Chemistry 101 Help β General Chemistry
Five high-difficulty chapters. One cumulative final. FMMC handles both.
Quick Answer
Chemistry 101: General Chemistry is a 3-credit, ACE-recommended Study.com course covering 13 chapters from atomic structure through thermodynamics. There are no assignments and no lab component β grading is 100 points from chapter tests and 200 points from the final exam. All assessments are open-book and unproctored. No prerequisites are required. Students who need a lab component should see Chemistry 112L.
What Chemistry 101 Covers
Study.com’s Chemistry 101 is a standard general chemistry course accepted at over 2,000 colleges for lower-division credit. It satisfies science general education requirements and serves as a prerequisite for nursing, pre-med, pre-pharmacy, and allied health programs requiring college-level chemistry without a lab. FMMC has supported students in these programs through general chemistry since 2016 β on Study.com and through traditional chemistry courses.
The course runs 13 content chapters. Each ends with a 15-question chapter test β open-book, up to 3 attempts, highest score counts. Chapter tests account for 100 of the 300 total points. The remaining 200 points come from the 50-question cumulative final exam.

| Ch 3: The Periodic Table | Periodic trends, element families, reactivity patterns | Low |
| Ch 4: Nuclear Chemistry | Radioactive decay, half-life calculations, nuclear reactions, applications | Medium |
| Ch 5: Chemical Bonding | Ionic and covalent bonds, Lewis structures, VSEPR, molecular geometry, polarity | High |
| Ch 6: Liquids and Solids | Intermolecular forces, phase diagrams, phase changes, crystal structures | Medium |

| Ch 8: Solutions | Molarity, solubility, concentration calculations, colligative properties | Medium |
| Ch 9: Stoichiometry | Molar mass, mole ratios, limiting reagents, theoretical and percent yield | High |
| Ch 10: Chemical Reactions | Balancing equations, reaction types, net ionic equations, predicting products | Medium |
| Ch 11: Equilibrium | Equilibrium constants (KπΆ, Kπ), ICE tables, Le Chatelier’s principle | High |
| Ch 12: Kinetics | Reaction rates, rate laws, reaction orders, Arrhenius equation, half-life | High |
| Ch 13: Thermodynamics | Enthalpy, entropy, Gibbs free energy, spontaneity, Hess’s law | Medium |
Where Students Get Stuck
The first four chapters are accessible. Units, atomic structure, the periodic table, nuclear decay β mostly conceptual and descriptive. Students with any high school chemistry background move through them quickly. The course changes character at Chapter 5.
Chapter 5 (Chemical Bonding) is where general chemistry starts demanding real problem-solving. Drawing Lewis structures correctly requires applying octet rule exceptions, formal charges, and resonance β all at once. VSEPR geometry adds a spatial reasoning component that trips up students who are strong at procedural chemistry but weak at visualizing molecular shapes. Students who rush Chapter 5 pay for it on the final, where molecular geometry questions appear repeatedly.
Chapter 7 (Gases) is the first chapter that is heavily calculation-dependent. The ideal gas law (PV = nRT) looks simple until students need to apply it with unit conversions, identify the correct variable to solve for, and combine it with Dalton’s law or Graham’s law in multi-step problems. Algebra errors and unit mistakes are the most common point-loss locations.
Chapter 9 (Stoichiometry) is where the gap between watching and doing becomes expensive. Students who watch the video lessons and feel like they understand limiting reagents are often surprised when the chapter test reveals they cannot execute the calculation independently. Multi-step mole conversions require procedural fluency that only comes from working problems repeatedly β not watching them solved. Students who enter the Chapter 9 test without having worked through problems from scratch routinely burn all three attempts.
Chapters 11 and 12 are the late-course spike. Equilibrium requires understanding K expressions, writing ICE tables correctly, and applying Le Chatelier’s principle to predict shifts β a combination of algebraic and conceptual reasoning. Kinetics introduces rate laws and integrated rate equations, which require identifying reaction order from experimental data. These two chapters together represent the largest cluster of final exam questions that students most commonly get wrong.
What makes Chemistry 101 harder than it looks: the five high-difficulty chapters are spread across the course β Chapters 5, 7, 9, 11, and 12 β not clustered at the end. There is no safe stretch where students can coast and recover. A student who struggles at Chapter 5 has eight more chapters to go, including two more high-difficulty spikes, before the final exam unlocks.
