Mixtures

There are two general types of mixtures: homogeneous and heterogeneous. Homogeneous mixtures are composed entirely of one phase (for instance, all liquid or all solid). A heterogeneous mixture is composed to mixed phases (such as a solid in a liquid, or a liquid and gas).

Homogeneous Mixtures:

salty water (where the salt is completely dissolved)

brewed tea or coffee

soapy water

a dilute solution of hydrochloric acid

hard alcohol

wine

Heterogeneous Mixtures:

sandy water

carbonated beverage or beer (the CO2 gas is mixed with the liquid)

orange juice with pulp in it

water with ice cubes in it

chicken noodle soup

RE:
All of the following are heterogeneous mixtures except: a. vodka, b. milk, c. a rock, d. sour cream?

Seriously, the fellow who said vodka is a solution is on the money. A rock except for our flawless diamond and other pure ores is probably a mixture. It happens to be in a solid form. You can mix dry corn meal with dry flour. The resulting powder is still a mixture. Milk and cream can be separated. Even the sour cream will “bleed” liquid as it settles.

Rock is NOT a mixture, let alone a heterogeneous mixture.

i am guessing vodka since the rest will eventually settle well except for the rock of course! lol

(Granite is an example of a composite rock.)
