I know you don't answer graded questions and I am not looking for you to straight up give me the answer to this but how do I even start? like I said before I know that the highest peak is 16amu which is Oxygen but do I just the vertical bar as a ratio? Like the next bar to the left (15amu?) is like 90% intensity? so like 9:10 ratio? There isn't even a 15amu element so please just give me some idea where to start. The place in the book it tells you to go to read has nothing about this stuff, its about finding empirical formulas from mass or percentages.... please help me!

In the glucose molecule, why is the oxygen at carbon 5 the one that reacts with carbon 1 when there is an additional carbon at the end of the chain, carbon 6? t Predictions: On a. Due to the chirality of the last carbon, carbon 6 b. Because carbon 5 is the last chiral carbon 4 C. Because the oxygen at carbon 5 is in alpha position just like the oxygen at carbon 1 Accessibility: Good to go O 8: 14 101 f5 % 5 f6 A 17 40 & 7 18 Ö 7 W f9 8 8 f10 9 19 11 F ) O n f12 81°F Cla
