I believe the answer is D) 158. Thanks
If dichloromethane is swapped out and ethyl acetate is used in its place, the extracts then obtained would be highly anti-radical and would be more efficient than dichloromethane.
Since "like dissolves like," ethyl acetate is a polar molecule that works well as a solvent to extract the polar caffeine molecules from coffee beans. The ethyl acetate molecules bind to the caffeine molecules, which then move through the bean cells' cell membranes. After all, the ethanol:water (1:1) solvent combination has been demonstrated to be the best for recovering catechins and delivering extracts with the highest antiradical activity.
Dichloromethane is a volatile colourless liquid used as an organic solvent in many industries. One of its main application is that it used to extract caffeine because of its highly effective solvent nature. Because DCM is a non-polar solvent and caffeine is readily soluble in DCM, it can easily be extracted without losing its aroma.

D is the answer so its correct and your welcome
Answer&Explanation:
This principle refers to those action which are legally permitted but are also likely to result to severe impact which wasn't initially intended like the death of a person as a side effect of the good action that was actual intended.
For example a doctor may give a patient some pills to relieve stress symptoms eventhough the doctor knows that this may have side effect such as actual shortening their life.
The doctor's intention are not to kill the patient but the death would be a side effect of the good results which are to reduce the patient's pain.
Another example is in the warfare where soldiers may go on a mission that requires that what ever action they take few civilian may get hurt in the process but the intention isn't to kill those civilian but it is a side effects of the good operation of eliminating the legitimate target which may be a threat to a country.

The correct answer is:
False.
Explanation:
It is important to consider that according to statistics and possible predictions about the demographic growth of racial diversities in the United States, it would be difficult to ensure exactly such behavior. What is true, is that the line of racial diversity is becoming increasingly blurred due to the high number of procreation and marriages between individuals of different races and places in the world as this is a multicultural country. The answer to the question is false, since according to the US Census Bureau the population in the country will be composed in its majority by non-Hispanic whites by the year 2042.
