Answer 11

You too :)

Answer 12

Actually can you help me with one more? @hedyeh99

Answer 13

Ok sorry for responding late

Answer 14

Its okay. Is tap water a heterogeneous or homogenous mixture? Explain your answer.

Answer 15

homogenous. a homogeneous mixture is uniform. a heterogeneous mixture (like soup) is not uniform

Answer 16

Okay how would I explain that? Why is it homogeneous? I thought it was heterogeneous. @hedyeh99

Answer 17

It is homogeneous because a homogeneous mixture is a mixture where the components that make up the mixture are uniformly distributed throughout the mixture. The composition of the mixture is the same throughout. There is only one phase of matter observed in a homogeneous mixture.

Answer 18

here are always two or more phases in a heterogeneous mixture, where you can identify a region with properties that are distinct from those of another region,

Answer 19

for example mixed nuts are heterogeneous: you can show that it isn't made of just pecans but also cashews and almonds and etc

Answer 20

homogeneous is like vinegar

Answer 21

cannot tell me there are different parts to vinegar, there are no lumps or solid pieces

Answer 22

Wait you confused me.. Is it homogenous or heterogeneous?

Answer 23

Okay nevermind I understand. 4. Is isopropyl alcohol (rubbing alcohol) a heterogeneous or homogenous mixture? Explain your answer.

Answer 24

water is homogeneous. It is one phase, same all throughout

Answer 25

isopropyl is the same, there isn't anything in a bottle of isopropyl alcohol that is different from the rest of the bottle

Answer 26

Okay thank you !! Now have a wonderful day! lol

Answer 27

Your welcome bye !
