Answer 2

bah. i'm doing your homework, but it's an interesting question. nitrogen and oxygen can be separated by burning out the oxygen with a flame - nitogen won't burn, under ordinary conditions (if at all - not a chemist), while burning can't occur, at all, without oxygen. the oxygen would be gone, but it would be seperate from the nitro.

salt and sugar could likely be separated by the application of heat. sugar strikes me as having a lower melting point than salt, so would liquefy, while the salt remained solid. how THEN to separate them is tricky. an extremely fine seive might do it, but it would be painfully slow and messy, if possible, at all. the real answer must be that one is soluble in a certain liquid which the other is not. look up salt and sugar (though sugar's a mixture of elements, itself, not a pure element, like salt), and see what will dissolve one, and not the other. alcohol or ether come to mind.
