Shaving cream is an example of which colloid type?

◦ Aerosol
◦ Foam
◦ Emulsion
◦ Sol
◦ Coagulate

Question 2

Solid KF has a lattice energy of 804 kJ/mol and a heat of solution (in water) of –15 kJ/mol. RbF has a lattice energy of 768 kJ/mol and a heat of solution (in water) of –24 kJ/mol. Which salt forms stronger attractions with water?

◦ KF, since it has a larger lattice energy.
◦ RbF, since it has a smaller lattice energy.
◦ KF, since it has a more negative heat of hydration.
◦ RbF, since it has a more negative heat of hydration
◦ They form equally strong attractions with water, since they both have negative heats of mixing.
