CHEM 1120 Review Exam – Dutta Chemistry Final Study Guide (ECU 2026)
what does an asymmetrical molecule say about the polarity? - ANS ✔✔typically polar
What does molar mass have to do with boiling point? - ANS ✔✔-decrease in size means
decrease in boiling point
-increase in size means increase in boiling point
what does intermolecular forces have to do with boiling point? - ANS ✔✔-stronger forces have
greater boiling points
Order of strongest to weakest intermolecular forces - ANS ✔✔-ionic
-hydrogen bonding
-dipole-dipole
-london disperson
What happens if you add/subtract to the left side of the equilibrium equation? (reactants) - ANS
✔✔-shift to the right
-it will either increase or decrease to make it even
what happens if you add a catalyst to equilibrium equation? - ANS ✔✔-increases the rate of the
reaction
-decreases amount of Eact needed (activation energy)
What happens if you increase the temperature in an equilibrium equation? - ANS ✔✔-increases
equilibrium concentration
What does acid have more of than a base? - ANS ✔✔hydrogen ions
