How many moles of 2-butanol are oxidised by 1 mole of dichromate?
1 mole of dichromate releases 3 moles of atomic oxygen during oxidation process so it may oxidize 3 moles of butanol.Added:The answer (three moles butanon) is correct, but not the explanation.This oxidation has nothing to do with 'oxygen atoms', instead CrVI (in bichromate) taking up 3 electrons to form CrIII cations.Secundairy alcohols, like 2-butanol, are only oxidised till a keton is formed (butanon), according to:3 (CH3)CHOH(C2H5) + Cr2O72- + 8 H+ --> 3 (CH3)CO(C2H5) + 2 Cr3+ + 7 H2OPlease note there is NO change in the number of 'oxygen atoms' in the 2-butanol changing to butanon.

What is the chemical formula for chromium II Phosphate?
Cr+2 P-3 ----> these are the ions and their charges. You know chromium's charge because of the roman numeralCr+2 Cr+2 Cr+2 P-3 P-3 ------> the charges have to add up to zero, so three +2 Cr ions plus two -3 P ions cancel each other outCr3P2 -----> simplify
What is the ion symbol of the cation of chromium?
The cation of chromium is Cr3+.
