The question I have to answer is: If two peaks of gas chromatogram are too close, what changes in experimental conditions (factors affecting separation) could you make to separate them more effectively? Answer: I thought the answer would be the length of the column. If you cha...

In gas chromatography, what would be the order of the retention times for your mixture (hexane and toluene)? What is the basis for your answer?
Organic Chemistry
To which class of compounds might the following molecule belong? C3H6O I am guessing, but is it ketone class? Can someone check for me.
Chemistry
I have to name this: [Co(H2NCH2CH2NH2)2]3+ And I think it is this: bis(ethylenediamine)cobalt(III) ion But can someone verify and check if I named it correctly. I am not sure if I am supposed to have the (III) or not.

Calculate pH of a solution by mixing 15.0 mL of .50 M NaOH and 30.0 mL of .50 benzoic acid solution (benzoic acid is monoprotic, its dissociation constant is 6.5 x 10^ -5). I am not sure whether I am supposed to do it by acid-base titration way or to use the formula -log (Ka)+...

A 19th-century chemist, Marcellin Berthelot, suggested that all chemical processes that proceed spontaneously are exothermic. True or False? I thought it was true, but then in my chemistry textbook, I could not find this person's name. Can someone verify whether it is true...

Oh sorry I forgot to write the charges. For then for the second one, it is supposedly look like this? 2Cu (2+) + [Fe(CN)6]^(4-) ==> Cu2 [Fe(CN6)] would that make this ionic equation correct?
