Question

1. Check all of the following statements that are true:

a. The value of q is always equal to the value of w for a reversible reaction

b. The energy change of the universe for any spontaneous process is always positive

c. The equilibrium constant is always equal to one for any system at equilibrium

d. The free energy change for any spontaneous process is always positive

e. None of these statements are true

f. The entropy change of the universe for any spontaneous process is always positive

g. The equilibrium constant is always greater than one for an extensive reaction

2. What mass of Na2SO4 is required to make 60 mL of a 0.20 M Na2SO4 solution? Report your answer to three places past the decimal point.

_____g of Na2SO4

3. Select all of the compounds below that are more soluble in water than in CCl4. (You should check anywhere from one to four boxes.)

HCl

NH3

FeCl2

Cl2

None of these are more soluble in water

2. Molarity = (mass/molar mass) X (1000/volume)

mass = (Molarity X molar mass X volume)/1000

= (0.2 X 142 X 60)/1000

= 1.704 g of Na2SO4

3. water is a polar solvent and it dissolves polar compounds

1.HCl

2.NH3

3.FeCl2
