Question

Which of the following is NOT a method used to physically separate components in a mixture?

chromatography

sublimation

distillation

precipitation

Answer 1

I think its option A.

Answer 2

@Nnesha @wwhitlock @whpalmer4

Answer 3

I answered this already ! >_>

Answer 4

Yeah, just want you to tell if I am correct.
@Nnesha, am I correct?

Answer 5

It's not A

Answer 6

We gave you a whole list of definitions for this stuff...

Answer 7

Oh oh, its must be B then?

Answer 8

It is B. Sublimation is not a filtration method. It's a matter state change

Answer 9

filtration/separation of components method*

Answer 10

i guess the last question was same like this
so first of all you need to know the definitions of all these words.
what do you think its A ??

Answer 11

why**

Answer 12

http://www.ccri.edu/chemistry/courses/chem_1030/Physical_Separation.pdf read this
if this doesn't make sense then google each word maybe you can find definition in easy words

Answer 13

I thought it was A, because I was not paying attention Nnesha.
I got confused with A and B.

Now I think its B because B is sublimation, sublimation = transition of the substance directly from a solid to the gas phase without passing through the intermediate liquid phase.

Answer 14

Chromatography: separation of components using filter paper held upright in solution. Lighter components migrate farther UP the filter paper

Sublimation: the transition from solid to gas directly with no liquid phase.

Distillation: the action of purifying a liquid by a process of heating and cooling.

Precipitation: the formation of a solid in solution via chemical reactions

Answer 15

Thanks @Nnesha!

Answer 16

So yes, B. Because it's the only one that's not a filtration.

Answer 17

Thx @kittiwitti1. Got ya.

Answer 18

I need to help with math now, @NvidiaIntely
Sorry. I can't help you anymore

Answer 19

Okay cya!

Answer 20

okay next time post the statement why you think ur answer is A,B,C or D
so it would be easy :=))

Answer 21

Okay thanks!

Answer 22

This smells like science. I've been around science before. It smells kinda like this.
