Answer:
You have a pressure change and temperature change - you can use the combined gas law:
P1V1/T1 = P2V2/T2
Where P1 = 1am
P2 = 0.8atm
T1 = 273K
T2 = 273 + 22 = 295K
V1 = 1.2lL
V2 = x

Answer:
If carbonyl oxygen of 4-hydroxypentanal is enriched with 
, then the oxygen label appears in the water .
Explanation:
- In the first step, -OH group at C-4 gives intramolecular nucleophilic addition reaction at carbonyl center to produce a cyclic hemiacetal.
- Then, one equivalent of methanol gives nucleophilic substitiution reaction by substituting -OH group in cyclic hemiacetal to produce cyclic acetal.
- If carbonyl oxygen of 4-hydroxypentanal is enriched with , then the oxygen label appears in the water produced at the end of reaction.
- Full reaction mechanism has been shown below.
Answer:
Explanation:
The correct answer is 19, 20 DHDP is more polar than DHA. This is as a result of the presence of two hydroxyl groups.
Answer:
Cystic fibrosis (CF) is a genetic disease that causes thick, sticky mucus to build up in organs, including the lungs and the pancreas. In a healthy person, mucus that lines organs and body cavities, such as the lungs and the nose, is slippery and watery. In people with CF, thick mucus clogs causes symptoms in the lungs and pancreas.
