Answer : The % of (+) limonene isomer = 79%
The % of (-) limonene isomer = 0%
The % of enantiomeric excess = 58%
Explanation : Enantiomeric excess (ee) is the measurement of purity used for chiral substances.
Given,
% of pure limonene enantiomer = The % of (+) limonene isomer = 79%
Therefore, The % of (-) limonene isomer = 0%
Formula used :

Where, ee → enantiomeric excess
Now, put all the values in above formula, we get the value of enantiomeric excess (ee).


= 58%
Explanation: Because ocean tides are the effect of ocean water responding to a gravitational gradient, the moon plays a larger role in creating tides than does the sun. But the sun's gravitational gradient across the earth is significant and it does contribute to tides as well.
The process of uranium mining generates what is called uranium tailings. These are the waste by products of uranium mining. Tailings contain the radioactive decay products of the uranium atom and these products are quite radioactive. Radioactive particles found in tailings can emit anywhere from twenty to one hundred times as much radiation as the natural levels at natural uranium deposits. These radioactive byproducts can lead to cancer if exposed.
