Steel wool wetted with vinegar is stuffed into a narrow mouth round glass bottle. A rubber balloon is then sealed over the mouth of the bottle. After several hours, the balloon inflates into the bottle in an inverted manner. What happened?
 
  A) Vinegar fumes are diamagnetic and as they accumulate above the liquid the steel wool is attracted thus inflating the balloon into the mouth of the bottle in an inverted manner.
  B) The caustic vinegar fumes get past the steel wool and deteriorate the balloon, which begins to sag into the bottle and inflate it in an inverted manner.
  C) The vinegar reacts with the steel wool by absorbing oxygen within the bottle thus decreasing the pressure. The greater outside pressure causes the balloon to inflate in an inverted manner.
  D) False The balloon inflates above the mouth of the bottle because the reaction between the vinegar and steel wool produces a gas which is forced upward because of increased pressure inside the sealed bottle.

Question 2

What is happening at the molecular level when a polar molecule like water interacts with a typical sodium ion?
 
  A) The water molecule aligns such that the oxygen interacts with the sodium.
  B) The water molecule aligns such that the hydrogens interact with the sodium.
  C) The polarity of the water molecule is altered making the oxygen more positively charged.
  D) The polarity of the water molecule is altered making the hydrogens more negatively charged.
  E) none of the above
