General Chemistry 2 ACS Final Review Questions
And Answers
What are the 4 types of intermolecular forces listed from weakest to strongest? ANS London dispersion,
dipole-dipole, hydrogen bonding, ion-dipole
What effect does IMFs have on surface tension? ANS surface tension increases as strength of IMF increase
What effect does IMFs have on viscosity? ANS viscosity increases as strength of IMFs increase
What effect does IMFs have on boiling point? ANS boiling point increases as strength of IMFs increase
Which are miscible in water: polar or nonpolar compounds/liquids? ANS polar
Draw a general phase diagram. Determine where the solid, liquid and gas phases reside. What are the "lines"
called and what is the name of the other two significant points. ANS
Solubility generally increases or decreases with increased temperature? ANS increases
What is dynamic equilibrium of a solution? ANS when rate of dissolution = rate of recrystallization
What factors effect the solubility of a gas? ANS temperature ( when temp increases, solubility decreases)
pressures (when pressure increases, solubility decreases)
what is molarity? ANS measurement of concentration
moles of solute/liters of solutuion
Which of the following are strong or weak acids?
1. HCl
2. HF
3. HBr
