what are...?

Question

homogeneous mixtures and heterogeneous mixtures?
and is sand water mixture an example of heterogeneous mixture and is salt water a homogeneous mixture?

i keep on reading about it, but im still kinda lost....i have a test tomorrow and i need help =(

Answer 1

Homogenous mixtures are the same throughout. Heterogenous mixtures are "chunky" with bits of different stuff floating around. A mixture of sand and water for instance, you've got chunks of sand sitting around in water, so it's heterogenous. A chocolate chip cookie is heterogenous, but a piece of white bread would be homogenous-- if that example helps.

Answer 2

yes and yes
