Answer: The required [a] for slotion will be -62.7
Explanation:
The specific rotation of pure quinine= -165
% of pure quinine= 69%
% of its enantiomer=ee=31%
Enantiomer excess =(ee)=excess of a single enantiomer/entire mixture×100
Now,
Excess of a single enantiomer=69% - 31%=38%
Entire mixture=69% + 31%= 100%
(ee)=38/100 × 100
=38%
Net rotation= 0.69-0.31=0.38
Hence, [a] for solution will be = -0.38×165= -62.7
Answer:Depending on the size of the tear, recuperation might take anywhere from 4 to 6 months or longer. Most activities can be resumed after six months, although the rotator cuff can take up to a year to heal.
Explanation:
Answer:
The answer is A a loss of surfactant.
Explanation:
The surfactant is a liquid that intervenes in the capillary-alveolus interface favoring the exchange of gases (oxygen, CO2) at this pulmonary level. For this reason, damage to type II pneumocytes will produce an alteration of this exchange.
