CHEM1100: Chemistry 1
About 3 hours 15 min on Lorea11 chapters1 school
Looking up CHEM1100 (Chemistry 1)? This is the 13-week general chemistry course STEM, pre-med, and allied-health majors take when the first quantitative chem class shows up on the schedule.
At University of Queensland, CHEM1100 is the code on the schedule, the textbook list, and the exam. This page follows Chemistry 2e (OpenStax) chapter for chapter - 11 chapters over 13 weeks - and opens a free Lorea course with no signup.
If you are asking "is CHEM1100 hard?" start with the failure points below, then drill the 11 OpenStax chapters instead of rereading the PDF.
Lorea is independent and not affiliated with University of Queensland.
What CHEM1100 covers
CHEM1100 covers Essential ideas and measurement, atoms/molecules/ions, composition and solutions, stoichiometry, thermochemistry, electronic structure and periodic trends, chemical bonding and molecular geometry, advanced bonding theories, gases, liquids and solids, solutions and colloids. The sequence matches Chemistry 2e (OpenStax), the open textbook this page is built from - 11 chapters across a 13-week semester, in the same order your lecture is likely to follow.
What makes CHEM1100 hard
Stoichiometry and limiting reagent (Ch 4) is the single biggest failure point; then VSEPR molecular geometry (Ch 7); unit conversion and significant figures trip students in week 1; gas law problem setup (Ch 9). Those are the spots students miss on timed CHEM1100 exams even after they "read the chapter." Drill them with retrieval - practice questions, blank figures, setup-only problem sets - not another highlight pass.

How to study for CHEM1100
1. Do the math before you reread
Start every week with the failure points in CHEM1100: Stoichiometry and limiting reagent (Ch 4) is the single biggest failure point; then VSEPR molecular geometry (Ch 7); unit conversion and significant figures trip students in week 1; gas law problem setup (Ch 9). Write the setup, not just the answer.
2. Keep a unit-and-formula card
Most CHEM1100 misses are unit errors or a missing conversion. One card for SI prefixes, gas-constant units, and ΔH signs beats a highlighted PDF.
3. Redraw structures from memory
Lewis structures, VSEPR shapes, and orbital diagrams have to come out of your hand, not the figure caption. Close the book and redraw.
4. Mix old chapters into new problem sets
Stoichiometry does not retire when you reach gases. Interleave two older chapters with the current one so the sequence stays loaded.
5. Sit a free practice pass
Use the free Lorea course for Chemistry 1 - no signup - and miss on purpose once so you know which of the 11 chapters still wobble.

FAQ
Is CHEM1100 hard?
Yes - CHEM1100 is a weeder for many students because of specific failure points, not because the textbook is obscure. Stoichiometry and limiting reagent (Ch 4) is the single biggest failure point; then VSEPR molecular geometry (Ch 7); unit conversion and significant figures trip students in week 1; gas law problem setup (Ch 9). Plan weekly retrieval around those, not a single reread of Chemistry 2e (OpenStax).
How many chapters is CHEM1100?
CHEM1100 is 11 chapters in this guide, aligned to Chemistry 2e (OpenStax): Ch 1 Essential Ideas; Ch 2 Atoms, Molecules, and Ions; Ch 3 Composition of Substances and Solutions; Ch 4 Stoichiometry of Chemical Reactions; Ch 5 Thermochemistry; Ch 6 Electronic Structure and Periodic Properties of Elements; Ch 7 Chemical Bonding and Molecular Geometry; Ch 8 Advanced Theories of Covalent Bonding; Ch 9 Gases; Ch 10 Liquids and Solids; Ch 11 Solutions and Colloids.
What textbook does CHEM1100 use?
CHEM1100 in this guide follows Chemistry 2e (OpenStax). Your section may assign a different commercial book; the chapter titles above are the OpenStax sequence used at the listed schools.
What is the difference between CHEM1100 and the next course in the sequence?
The next course after CHEM1100 depends on the department at University of Queensland. Use this page for the current code; look up the sequel on your campus schedule rather than assuming a shared next number.
Which schools use the CHEM1100 code?
CHEM1100 is used at University of Queensland. If your campus prints this exact code, the chapter list on this page is the one to study against.
Are there free CHEM1100 flashcards?
Yes. The free Lorea Chemistry 1 course linked on this page covers all 11 Chemistry 2e (OpenStax) chapters as retrieval practice — use it like CHEM1100 flashcards without signing up.
What is on CHEM1100 exam 1?
Exam 1 in CHEM1100 usually covers the first third of the term — often Essential Ideas, Atoms, Molecules, and Ions, Composition of Substances and Solutions, and more depending on your syllabus. Match the chapter list above to your exam date; the free Lorea course lets you run retrieval on those units before the midterm.
