im having trouble with a few points from the yr 11 chem. syllabus! can anyone help me out plzzzz????

* explain the relationship between the reactivity of an element and
the likelihood of its existing as an uncombined element.
* Identify and describe procedures that can be used to separate
naturally occurring mixtures of: solids of different size, solids and
liquids, dissolved solids in liquids, liquids, and gases.
* Apply systemactic naming of inorganic compounds as they are i
introduced in the laboratory
* Identify IUPAC names for carbon compounds as they are
encountered

YOUR HELP IS GREATLY APPRECIATED!!!!!!

(1) More reactive elements are likely to react with their environments, for example they may react with oxygen to form oxides. But unreactive elements won't react with the atmosphere or the surrounding environment so they are likely to be found as elements which are uncombined.
(2) You could boil the liquid off, you could use different size filter papers etc.
(3) This is just ordinary chemical naming. What exactly do you need help with?
(4) This is the organic part. Again, what exactly don't you understand in this section?

THANX rama!! so for question 3 do i just name inorganic compunds? and for question four i dont get the IUPAC

IUPAC just stands for International union of pure and applied chemistry. Its the standard that we follow when we name chemical compounds. They set the rules (naming rules, or nomenclature) that we use in chemistry.

ohhh i seee!! thanks!! sorri to take up ur time lol

Inorganic carbon compunds ? Arent they hydrocarbons like ... propane, butane ?

They all have a suffix, their chemical formulas are:

-ane, with C(n)H(2n+2) and a single bond
-ene, with C(n)H(2n) and a double bond
-yne, with C(n)H(2n-2) and a triple bond

Prefixes determine the number of carbon atoms in a molecule -

meth-
eth-
prop-
but-
pent-
hex-
hept-
oct-

Octane (C8H18) happens to be petrol, anyway, it has an -ane suffix, so it has twice as much hyrdogen atoms as there are carbon atoms plus an extra two.

Ethylene has a -yne suffix, so it has twice as many hydrogen atoms as there are carbon atoms, with two less ...

Hydrocarbons are organic compounds. Inorganic compounds are those that you are familiar with from year 7, like metal compounds and oxides etc.

Google says inroganic compounds are:

"Chemicals that do not contain carbon, which is usually associated with life processes; for example, metals are inorganic."

organic compounds are carbohydrates, protein, lipids, and nucleic acids Go bio!

OMG I love you!!!!!!

We did not get taught this at all (among other things, our teacher is crap) !!!! And I have been looking all over for it!!!!

Thankyou!!!!!!!
