Answer: Disaccharides
Explanation:
Disaccharides can be defined as the combination of two monosaccharides which combines together to form a disaccharides.
These are formed by the combination of sugars. The process is hydrolysis as it releases water after the reaction is complete.
Two monosachrrides are joined together by the glycosidic linkage. Some common examples are maltose, sucrose and lactose.
Answer:
See explanation
Explanation:
Accidental overlap of signals are common in H-1 NMR than in C-13 NMR for the following reasons;
1) 13C has a very low natural abundance compared to H-1
2) 13C nucleus is s many times lesser in NMR sensitivity than H-1 nucleus.
3) As a result of its low abundance, 13C-13C coupling is not common.
4) Longer relaxation times do not give room for integrations.
5) Peaks in 13C spectra mainly consists of single lines.
As a result of all these, 13C-NMR spectra take longer to acquire than H-NMR. Hence, accidental overlap of signals is much more common in H-1 NMR than in C-13 NMR.
Assuming that the ammonium sulfide formula is (NH4)2<span>S then you can see that there are 2 nitrogen, 8 hydrogen and 2 sulfur atoms for every ammonium sulfide. If the amount of ammonium sulfide is 8.9 moles, then the number of hydrogen atoms should be: 8/1 * 8.9 mol= 71.2 moles.
If you are asked the number of individual atoms you need to multiply it with Avogadro number like this : </span>71.2 moles * 6.02 * 10^23= 4.28 *10^25
