MIXTURES
Combination of two or more substances that are not chemically combined
MIXTURES MAY BE HOMOGENEOUS OR HETEROGENEOUS
COMPOUNDS
A pure compound has the same elements and the same amount of elements all of the time
a mixture can be two or more different compounds (or elements) in an area (i.e a beaker, the atmosphere)
element is a 'pure' form that contains just the element it's self. They are all listed on the Periodic Table A compound is a substance made up of different elements that are all chemicaly bonded together. (By either ionic or covalent bonds) A mixture is a 'mix' of different compounds or elements that are not bonded together
The components of a mixture can be separated by purely physical means whereas a compound can only broken into its components by chemical means. Physical means can be separation by simply sorting out the components by eye such a sand and popcorn, or by dissolution where components dissolve to different degrees, by distillation where the components have different boiling points. To separate the components of a compound results in the destruction of the compound. Sodium chloride or common salt is a compound. Using chemical means it can be separated into sodium and chlorine. The former is a metal the latter is a gas and they are both entirely different to the white solid sodium chloride. When placed together they can react violently releasing heat and light to reform the original compound sodium chloride. Another compound is water however it can be a component of a mixture. Sea water is a mixture made up of several compounds water being the main component and sodium chloride being the second most important one. However the are many other components all dissolved in the compound water. Thus a mixture can contain two or more compounds. However a compound can never contain mixtures.
what are the two type of pure substances?
element:
compound:
Yes, both are material.
mixture-things that can be seprated. solutions-things that can't be separated

it's a mixture compound. Kind of a confounded compound mixture.

a substance produced when elements combine and whose properties are different from each of the elements. that's a compound. a mixture is a composition of two or more substances that are not chemically combined with each other and are capable of being separated. a compound is like C6H12O6 or glucose (plant sugar) or H2O and a mixture is like a pizza, with many different compounds.

Compare and contrast it with what?
1. Compare 2. Contrast
Is gasoline a element a mixture or a compound
mixture
Water is a compound
compare is when you compare two things that are the same and contrast is when you compare two things that are different.
It is a mixture.
