Explain the difference between filtration and decantation (see the "general laboratory equipment and procedures" section of this manual). why might one want to use filtration in this experiment rather than decantation?

It is the direct separation of the entire solution with the help of a filter, where the solid particles are trapped on the filter and liquids passes away.

It is the process of pouring the liquids away from a precipitated solid, keeping the solid in the original container.

In the experiment mentioned above, filtration will be more effective so that all the solid particles and solvents are filtered out and pure liquid if separated.

in this scenario it would be the consumer demand as most influential in making the decision. the band members need to figure out where and from whom they will make the most money, in other words who out of the two consumer groups - football fans or car drivers - will spend their money, who is more likely to contribute to their cause and buy what they are offering.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
