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.

Answer: Representative Greggs won her last election by more than 7% of the vote and feels confident that she is likely to be reelected. This may give her more room to vote with her conscience on bills, even if a majority of her constituents disagree with some of her positions; this is an example of trustee behavior.
However, Representative Carver is a Democrat representing a district that usually votes Republican and won his last election by only 1% of the vote, so he may feel in danger of losing his next election. He is more likely to act as a delegate, prioritizing his constituents' wishes over his own judgment, in order to guarantee a win in his next election.
Explanation:
Answer:
The answer is: letter D, using reason and observation to solve a problem.
Explanation:
Renee Descartes was a French philosopher who founded the modern philosophy while Francis Bacon was an English philosopher who developed the scientific method. According to both of them, a critical step in reaching a sound scientific conclusion is by using reason and observation in order to solve it.
Observation and perceptual experiences co-existed in order to predict the outcome. In order to solve a problem,<u> the necessity to reason out is important. </u>The solution needs to have a reason in order to aid the readers how the researcher came up with it.
For example, Renee Descartes employed the cause-and-effect method when it comes to problem solving. He emphasized that reason was <u>the main source of the researcher's knowledge.</u>
Thus, this explains the answer.
Answer:
The answer is d. how close the students lived to one another.
Explanation:
Friendships were moke likely to start the closer people were physically, Festinger and his team found out. . A similar pattern was observed regarding attitudes; attitudes of dormitory residents showed a tendency to converge.
