Heterogeneous and homogeneous?

Question

What is the difference between heterogeneous and homogeneous? How can you tell them apart? (by sight)

Answer 1

A MIXTURE is a combination of two or more substances that are not chemically united and do not exist in fixed proportions to each otherA mixture can be physically separated into pure compounds or elements.A pure compound has a constant composition with fixed ratios of elements.Just about everything that you can think of is probably a mixture. Even the purest of materials still contain other compounds as impuritiesAlthough it is almost physically impossible to isolate absolutely pure substances, a substance is said to be pure if no impurities can be detected using the best available analytical techniques.Mixtures may exhibit a changing set of physical properties.For example, mixture of alcohol and water boils over a range of temperatures. Physical properties such as boiling point or melting point of pure substances are invariant.For example, pure water boils at 100 degrees C

Homogenuos mixtures-The prefixes "homo"- indicate sameness
Heterogenuos mixtures-The prefixes: "hetero"- indicate difference.
A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions
A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.
Corn oil is homogeneous, White vinegar is homogeneous. A sugar solution is homogeneous since only a colorless liquid is observed. Air with no clouds is homogeneous

For example beach sand is heterogeneous since you can see different colored particles. Vinegar and oil salad dressing is heterogeneous since two liquid layers are present, as well as solids. Air with clouds is heterogeneous, as the clouds contain tiny droplets of liquid water.

SOLUTIONS are homogeneous mixtures.
A solution is a mixture of two or more substances in a single phase. At least two substances must be mixed in order to have a solution. The substance in the smallest amount and the one that dissolves or disperses is called the SOLUTE. The substance in the larger amount is called the SOLVENT. In most common instances water is the solvent. The gases, liquids, or solids dissolved in water are the solutes.

Answer 2

Homogeneous mixtures
Homogeneous are mixtures that have definite, true composition and properties. For example, any amount of a given mixture has the same composition and properties. Examples are solutions and some alloys (but not all). Homogeneous mixtures can also be called "impure substances." A homogeneous mixture is a uniform mixture consisting of only one componet. Examples are gasoline and margarine.

Heterogeneous mixtures are mixtures without definite composition, for example, granite. Salad is a typical example of this kind of mixture. Heterogeneous mixtures are said to have several phases (not to be confused with phases of matter). An example is the parts of a heterogeneous composition, which can be mechanically separated from the rest. Examples include: salad, trail mix, milk (before homogenization).

Answer 3

Heterogenous will look differnt throughout
Homogeneous will look the same through out.

Salt & Pepper mixture: Heterogeneous
Salt & Water mixture: Homogeneous

Answer 4

a heterogeneous mixture is a mixture with substances that you can tell apart, like rocks on the bottom of a cup of water.
a homogeneous mixture is a mixture where you cant tell the difference between the substances, so it looks like there is only one thing in the test tube

i use this to remember that :
hetero = boy and girl (you can tell apart)
homo = boy and boy (you cant tell apart)

Answer 5

Homogeneous is made up of the same properties and heterogeneous is made up different properties, sorry not much help huh?

Answer 6

Homo-geneous is exactly 100% presevered in ice, with a terminator called S.A.T.A.N. Hetero-geneous is the exact moment of intinial {LIMBO} a wooded area so dark that you can not find your way out, at least until the next SUN-RISE.

Answer 7

Here is a little trick to tell the difference between them just think of homosexual as liking the SAME gender, and heterosexual as liking the OPPOSITE gender. (No offence to gay people.)
That is just how I always remembered it.
