Cornell CHEM 2070: General Chemistry I
CHEM 2070 is Cornell's first general chemistry course — stoichiometry, atomic and molecular structure, bonding, thermochemistry, gases, and intermolecular forces — required for engineering, science, and pre-health tracks, with a lab component and curved evening prelims.
Fennie is independent and not affiliated with Cornell University. This is an unofficial study guide.
Build my CHEM 2070 study planWhat makes it hard
The prelim style is the shock: time-pressured, multi-step problems where stoichiometry fluency is assumed from week three onward. Students who follow lecture fine but practice few problems discover the gap on prelim one, and because grading is curved against a room of pre-meds and engineers, 'decent' preparation can land below average.
What you'll cover
- • Stoichiometry and the mole
- • Atomic structure and periodicity
- • Chemical bonding and molecular geometry
- • Thermochemistry
- • Gas laws
- • Intermolecular forces
The CHEM 2070 study guide
How to study for Cornell CHEM 2070, step by step.
- 1
Make stoichiometry automatic in the first three weeks
It's embedded in everything CHEM 2070 does after week three. Drill mole conversions and reaction stoichiometry daily until they cost no thought — slowness here bleeds points all semester.
- 2
Solve problems daily with solutions closed
Following lecture fine while practicing few problems is the classic setup for a prelim-one shock. Work problems cold every day and redo your misses the next.
- 3
Let units carry you through multi-step problems
Write units on every quantity and make them cancel. Dimensional analysis turns the course's long calculation chains into guided paths and catches errors before they're graded.
- 4
Work past prelims under time pressure
In the week before each evening prelim, do old exam-style questions timed and without notes. The exams are time-pressured and curved, so speed has to be trained, not hoped for.

How Fennie helps with CHEM 2070
Fennie's Daily Plans make CHEM 2070 survivable the proven way: daily problem sets from week one, stoichiometry drilled to automaticity, review paced to the evening prelim dates. Chat unpacks multi-step problems with the reasoning visible at each step, and practice problems under time expose gaps before the curve does.
FAQ
Is CHEM 2070 at Cornell hard?
It has a weed-out reputation, and the curved evening prelims are why: time-pressured multi-step problems in a room of pre-med and engineering students set a high bar. Daily problem practice consistently beats it; passive studying consistently doesn't.
How do I pass CHEM 2070?
Make stoichiometry automatic in the first three weeks — it's embedded in everything after. Then solve problems daily without solutions open, and work old prelim-style questions under time limits before each evening exam.
Should I take CHEM 2070 or CHEM 2090?
CHEM 2090 (Engineering General Chemistry) is the one-semester engineering option, while CHEM 2070 is the standard first course leading to CHEM 2080. Check your major's requirement — they target different programs and aren't always interchangeable.
