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: Can you give me more context or more story so I could help Answer?
Answer:
When early humans began farming, they were able to produce enough food that they no longer had to migrate to their food source. This meant they could build permanent structures, and develop villages, towns, and eventually even cities. Closely connected to the rise of settled societies was an increase in population.

<u>Answer:</u>
The process followed in one's moral development
<u>Explanation:</u>
The cognitive development approach was developed by Jean Piaget. It explains how children develop a mental model of the world. Jean Piaget has disagreed at the point that intelligence is a fixed trait. He focused on cognitive development is the result of the interaction between biological environmental factors. He was the first psychologist who did a systematic study of cognitive development.
<u>There are three components of Piaget theory areas :</u>
- Schema
- Equilibrium
- Cognitive development
- Accommodation and assimilation
These components play a part in the cognitive and moral development of a child.
