General chemistry essentials
Atomic structure, bonding, stoichiometry, equilibrium, acids and bases.
General chemistry is the language of change. The MCAT tests whether you can predict direction, compare magnitudes, and choose the right relationship before doing math. If you can read the chemical story in a passage, the calculations are straightforward.
- Predict direction before calculating
- Periodic trends explain reactivity
- Limiting reagents control yield
- Equilibrium shifts follow Le Chatelier
- Buffers resist pH change via conjugate pairs
Think of a reaction you struggled with. Was the error in predicting direction or in the math? Write one sentence on how you will avoid it next time.
