Erika Shared "Chemistry Picmonics" - 3 Picmonics
With Picmonic, facts become pictures. We've taken what the science shows - image mnemonics work - but we've boosted the effectiveness by building and associating memorable characters, interesting audio stories, and built-in quizzing. Whether you're studying for your classes or getting ready for a big exam, we're here to help.
Chemistry Picmonics
Hydrogen Bonds
- Stronger than London Dispersion Forces
- Stronger than Dipole-Dipole Interactions
- Hydrogen is bound to a Highly Electronegative Atom
- Hydrogen has a Partial Positive Charge
- Electronegative Atom has a Partial Negative Charge
- Partial Positives Interact with Partial Negatives
- Hydrogen Bonds Increase Boiling Point

Spontaneous vs. Nonspontaneous
- Spontaneous at Low Temperatures
- ΔH is Negative
- ΔS is Negative
- Spontaneous at High Temperatures
- ΔH is Positive
- ΔS is Positive
- Spontaneous at All Temperatures
- ΔH is Negative
- ΔS is Positive
- Nonspontaneous at All Temperatures
- ΔH is Positive
- ΔS is Negative

Gibbs Free Energy
- ΔG = ΔH-TΔS
- If ΔG is Negative, the reaction is Spontaneous
- If ΔG is 0, the reaction is at Equilibrium
- If ΔG is Positive, the reaction is Nonspontaneous
