THE nitroso-group in an aromatic nitroso compound appears to be chemically abnormal. Thus, in the case of nitrosobenzene, failure to prepare salts or coordination compounds in which the nitroso-nitrogen acts as a donor atom, shows the accepted formula (1), with a tercovalent nitrogen atom, ...
manganese, nickel, vanadium, silicon and carbon, as well as ternary alloys with chromium, have made it possible to work out the whole required complex of parameters of nitrogen interaction in liquid iron alloys, including the self-interaction parameters of nitrogen-nitrogen and nitrogen-alloying elem...
What is the empirical formula of an oxide of nitrogen that contains 63.64% nitrogen by mass? What is the formula for 1 lithium atom, 1 nitrogen atom and 3 oxygen atoms If the formula of an oxide of element X is XO, what is the formula of the nitride of X?
