In a compound the sum of oxidation states of the elements contained is zero.
E1 + E2 + ... = 0
If you know the oxidation states of the elements E1... you can calculate the oxidation state of the element E2.
It is determined from known oxidation states of other elements.
If I was given an unknown liquid and asked to determine if it was an element, a compound, or a mixture I would heat the unknown liquid up to see if any compounds separated from the unknown liquid. After that I would get a microscope and look to see if it is a pure element. Then I would get a Platelet separation machine and put the liquid in the machine to see if the liquid separated. Thats how I would determine if the an unknown liquid is an element, a compound, or a mixture.
An Element ... A substance that cannot be broken down into simpler substances by chemical means.
The mineral oil prevents oxygen from entering the medium and allows for detection of possible fermentation of the unknown bacteria.
