Which of the following compounds would least likely act as an acid?
 
  A) SO4-2
  B) HSO4-1
  C) H2SO4
  D) NH3
  E) CH3CO2H

Question 2

Why does iodine, I2(s), spontaneously sublime at room temperature?
 
  A) The contact of iodine, I2(s), with the water vapor in the air causes the sublimation process.
  B) Iodine, I2(s), pulls Image from the air as it self-oxidizes under sublimation to I2(g).
  C) There is an increase in entropy as solid iodine, I2(s), sublimes into iodine vapor, I2(g), because in the gaseous phase energy is more readily dispersed.
  D) The reaction of I2(s) subliming to I2(g) is highly exothermic and therefore proceeds spontaneously.
