Question 1

How much energy is needed to convert 57.2 grams of ice at 0.00°C to water at 75.0°C?
    specific heat (ice) = 2.10 J/g°C
    specific heat (water) = 4.18 J/g°C
    heat of fusion = 333 J/g
    heat of vaporization = 2258 J/g

◦ 17.9 kJ
◦ 2.05 kJ
◦ 28.1 kJ
◦ 37.0 kJ
◦ 147 kJ

Question 2

How would you expect the melting point of CF4 to compare to that of RbF?

◦ It should be lower because RbF forms an extended ionic crystal lattice, whereas CF4 is a covalently-bonded small molecule.
◦ It should be similar since they are both ionic solids.
◦ It should be higher because the bonds are stronger due to the higher charge on C (+4).
◦ It should be higher because CF4 is larger than RbF.
◦ It is not possible to say anything about their melting points without more information.

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
