A gas chromatogram of the organic components of a sample of beer using a column that separates compounds on the basis of their relative boiling points provides a GC trace with several peaks. Two of the smaller peaks with retention times 9.56 and 16.23 minutes, are believed to be ethyl acetate and ethyl butyrate respectively.
a. From the above information, which component of the sample, ethyl acetate or ethyl butyrate, elutes faster? What are the reported boiling points of these two substances?
b. What GC experiment(s) could you perform to confirm the identity of the peaks at 9.56 and 16.23 minutes?
c. Suggest two ways in which you could adjust the conditions of the experiment so as to reduce the retention time for all components in the sample.

The diagram below shows a cell placed in a solution. a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution. only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it. it will expand as water moves into it. it will shrink as water moves into it.
