Answer 2

So which one doesnt look uniform throughout,

Answer 3

soom in by 10x and which one looks different

Answer 4

zoom*

Answer 5

B?

Answer 6

3 of them are solutions, for example saline is salt water, the salt molecules are dissociated and uniformly spread throughout, it would look the same if you looked at any area of the solution

Answer 7

so thats wrong

Answer 8

It is the soup, there are definite phase boundries between different parts of the mixture

Answer 9

if you zoom in on a certain area, it will look different than if you zoomed in on a different area

Answer 10

What is the formal definition of homogeneous? I always think of it as "unchanged under zoom" function kind of?

Answer 11

I always think of this defenition, it is more of a math kind:

having the property that if each variable is replaced by a constant times that variable the constant can be factored out : having each term of the same degree if all variables are considered

Answer 12

zoom function

Answer 13

in chem they usually say

of uniform structure or composition throughout

Answer 14

which is the same, if you zoom (multiply by a constant), the picture looks still uniform throughout

Answer 15

is it c

Answer 16

I said above, it is the soup

Answer 17

But it has mixture

Answer 18

that is why it is not homogeneous

Answer 19

a solution , is homogeneous

Answer 20

ohh

Answer 21

if you can see definite places that look different than the whole thing, it is not homogeneous

Answer 22

All the others look the same everywhere

Answer 23

See what i mean with zooming? if you zoomed into a glass of soda, it will still look like soda, if you zoomed into a bowl of soup, it may just look like a carrot now, instead of soup
