WebExisten tres sistemas de nomenclatura química: Sistema estequiométrico o sistemático (recomendado por la IUPAC). Nombra los compuestos en base al número de átomos de cada elemento que los forman. Por ejemplo: El compuesto Ni 2 O 3 se llama trióxido de diníquel. Sistema funcional, clásico o tradicional. WebThe initial rate of P2H4 formation was not affected by lowering the PH3 temperature to 227 or 157 K. The yield was greater at 157 K because the P2H4 condensed and was protected from further destruction. The initial quantum yields for the formation of P2H4 and H2 in PH3-NH3 mixtures were comparable to those observed for PH3 alone. phonefax
