The Ap Chemistry Exam | Cracking

State your direct answer (e.g., "The boiling point of NH3cap N cap H sub 3 is higher.")

Usually, only one point on the entire exam is dedicated specifically to sig figs—don't let them paralyze you, but keep them in mind for the FRQs. Cracking the AP Chemistry Exam

This is the "why" behind everything. If you can explain how polarities and forces (like London Dispersion or Hydrogen bonding) affect boiling points and solubility, you’ve won half the battle. State your direct answer (e

Cite the data provided or the specific intermolecular forces involved. Reasoning: Connect the two. "Because NH3cap N cap H sub 3
