In which situation will screening be used to separate a mixture? a. if the mixture is a solid suspended in a gas b. if the components have different boiling points c. if the mixture is a solid dissolved in a liquid d. if the components have different colors

Hello!

I believe the answer is

A) if the mixture is a solid suspended in a gas

Option (A) is the correct answer.

Explanation:

When granular solids are separated out according to their size then this process of separation is known as screening.

So, when a solid substance dissolves in a liquid then its molecules will dissociate into ions. Therefore, its particles cannot be separated out by screening.

Therefore, when solid particles are suspended in a gas then they can be separated out easily through the process of screening.

Thus, we can conclude that in a situation where the mixture is a solid suspended in a gas then screening be used to separate a mixture.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

what is the actual question though?
