Study.com Chemistry 112L Help — Chemistry II with Lab
The lab-bearing sequel to Chemistry 101 — harder content, a separate Labster fee, and everything that comes with it. FMMC handles all of it.
Quick Answer
Chemistry 112L: Chemistry II with Lab (SDCM-0195) is a 4-credit, ACE-recommended Study.com course — 3 semester hours for the lecture content and 1 semester hour for the lab. It covers 12 content chapters plus 11 required virtual lab experiments completed through Labster, a separate platform with its own subscription fee not included in Study.com membership. Grading is 100 points from chapter tests and 200 points from the final exam. The Labster labs must be completed before credit is awarded.
Labster — What to Know Before You Enroll
Labster virtual lab access is not included in your Study.com membership. You must purchase a separate Labster subscription and complete 11 assigned virtual experiments before the lab credit hour applies. Budget for this additional cost before enrolling.
What Chemistry 112L Covers
Chemistry 112L is the second course in Study.com’s two-course general chemistry sequence. Where Chemistry 101 covers bonding, gas laws, and stoichiometry, Chemistry 112L continues with kinetics, equilibrium, and electrochemistry — then extends through atmospheric, nuclear, and organic chemistry. It transfers for 4 semester hours of lower-division credit at over 2,000 colleges.
Chapter 1 is different from all other Study.com chapters — it is not a content chapter with a chapter test. It contains the Labster virtual lab assignments. Students must complete these 11 labs alongside the content chapters to unlock full credit. The remaining 12 chapters each end with a 15-question chapter test: open-book, up to 3 attempts, highest score counts.
| Chapter | Topics | Difficulty |
|---|---|---|
| Ch 1: Labster Labs | 11 virtual lab experiments — separate Labster subscription required | See note |
| Ch 2: Chemical Reaction Kinetics | Reaction rates, rate laws, reaction orders, half-life, Arrhenius equation | High |
| Ch 3: Equilibrium | Equilibrium constants (Kc, Kp), ICE tables, Le Chatelier’s principle | High |
| Ch 4: Acids, Bases & pH | Strong and weak acids/bases, pH and pOH, neutralization, buffers | Medium |
| Ch 5: Acid-Base Equilibrium | Ka and Kb calculations, buffer design, titration curves, Henderson-Hasselbalch | High |
| Ch 6: Solubility Equilibrium | Solubility product (Kₛₚ), common ion effect, molar solubility calculations | Medium |
| Ch 7: Entropy & Thermodynamics | Enthalpy, entropy, Gibbs free energy, spontaneity, Hess’s law | Medium |
| Ch 8: Electrochemistry | Oxidation-reduction, cell voltage, standard reduction potentials, Nernst equation | High |
| Ch 9: Atmospheric Chemistry | Atmospheric composition, ozone chemistry, greenhouse gases, pollution | Low |
| Ch 10: Metals & Nonmetals | Properties of metals and nonmetals, industrial and biological applications | Low |
| Ch 11: Coordination Compounds | Transition metal complexes, ligand types, naming, coordination number | Medium |
| Ch 12: Nuclear Chemistry | Radioactive decay types, half-life calculations, radiometric dating, applications | Medium |
| Ch 13: Organic Chemistry | Hydrocarbons, functional groups, naming, properties of major organic compound classes | Medium |
Where Students Get Stuck
Chemistry 112L picks up where Chemistry 101 leaves off — it assumes fluency in stoichiometry, equilibrium basics, and acid-base concepts before Chapter 2. Students who struggled with the harder Chemistry 101 chapters and still passed will find those gaps exposed immediately.
Chapter 2 (Chemical Reaction Kinetics) introduces rate laws, which require determining reaction order from experimental data — not from a formula, but by analyzing how rate changes when concentration changes. Students who approach this as a straightforward calculation exercise without understanding what the data is telling them consistently burn chapter test attempts.
Chapter 3 (Equilibrium) is where ICE tables become the central tool. Students who can write an equilibrium expression (K = products/reactants) often still cannot set up an ICE table correctly under test conditions — particularly when the problem involves small K values that require approximations, or when the equilibrium involves a gas-phase reaction with different units. The chapter test rewards procedural fluency, not conceptual understanding alone.
Chapter 5 (Acid-Base Equilibrium) layers a second judgment call on top of ICE table work: before students can even begin an equilibrium calculation, they need to correctly identify whether the acid or base in the problem is strong or weak. Strong acids and bases are solved differently — no ICE table needed — while weak ones require Ka or Kb setup. Students who mix up these paths, or who enter Chapter 5 without a reliable ICE table procedure from Chapter 3, fail the chapter test on the first attempt at a high rate. This is particularly common among students who have been away from quantitative chemistry for a semester or more — the algebra-chemistry fluency that Chapter 5 demands does not come back quickly from reading alone. FMMC’s chemistry help service covers both chapters specifically.
Chapter 8 (Electrochemistry) is the last high-difficulty chapter and the one that most often determines the final exam outcome. Cell voltage calculations require identifying oxidation and reduction half-reactions, applying standard reduction potentials correctly, and using the Nernst equation for non-standard conditions. Sign errors in reduction potential problems are the most common point-loss mechanism on the final.
The grading math: four High-difficulty chapters out of twelve. Score 55% on those four and 90% on the remaining eight — your chapter test average is 78 out of 100, and you need 132 out of 200 on the final to pass. That is 66% on a 50-question cumulative exam. Possible — but the Labster labs must also be completed, adding a separate completion requirement before credit applies.
