Ap Biology question...pretty easy?
Dehydration reaction involve the removal of water for every bond formed. 10 glucose molecule would form 9 glycosidic bond, therefore 9 molecules of H2O would be removed from the Polymer(18 Hydrogen atom and 9 Oxygen atom). 10 Molecules of C6H12O6=(C6H12O6)*10=C60 H120 O60(I spaced it to avoid confusion). Removing the 9 molecules of water(18H and 9O), C60 H120 O60-9H20=C60H102O51. For 9 molecules of glucose, it is the same process, 8 glycosidic bond is formed. (C6H12O6)*8=C54H108O54-8H20=C54H92O46 Note the ratio of Hydrogen to Oxygen in all the cases is always 2:1.

How would you rank the following classes from easiest to hardest: AP Biology, AP Chemistry, AP Physics, IB Biology, IB Chemistry, and IB Physics?
I don’t know much about the IB program but can speak on the AP classes. For me, the three classes are placed on a spectrum. AP Biology is the most memorization heavy, AP Physics is the most heavily based on raw problem-solving, and AP Chemistry is in between (I took the latter two in high school). So it really depends on your strong points when it comes to studying. If unlike me you are really apt at memorization, AP Biology will probably give you less trouble than the others. Of course, math was always my true passion, so the sciences that relied more heavily on math came more easily to me.
