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.

Over time, chronic hepatitis B virus and hepatitis C virus infections can progress to advanced liver disease, liver failure, and hepatocellular carcinoma. Unlike other forms, more than 80% of hepatitis C infections become chronic and lead to liver disease. When combined with hepatitis B, hepatitis C now accounts for 75% percent of all cases of liver disease around the world.
