How many litres of oxygen (at STP) are required for complete combustion of 39 g of liquid benzene?<br>(Atomic weights: C = 12, O = 16, H = 1)
One mole of N2H4 loses 10 moles of electrons to form a new compound Z.Assuming that all the nitrogens appear in the new compound, what is the oxidation state of nitrogen in Z? (There is no change in the oxidation state of hydrogen)
