I was wondering if organic chemistry required a lot of general chemistry knowledge. My prof for general chem is unknown and she could be terrible, so i was wondering even if i bombed gen chem (i shoul
There seems to be some major inconsistencies about the ratio and enthalpy. Some websites claim you should always use 8:3, Iron: Aluminum. Some say 1:2, some the reverse. Some say that Iron(II, III) Ox

Im working on a AP chemistry summer-assignment and have a few questions:
1) How many carbon atoms are in a 5.00 gram sample of sucrose, C12H22011?
-This is how I solved it:
5.00g/342.34g (molar mas
does this reaction go to completion?
