6) In order that the above conversion of one compound to another may be accomplished, the chemical properties of each compound must be understood. 为使上述转化(由一种物质转化成另一种物质)能够实现,必须了解每一种物质的化学性质。 7) Again, the solution of this problem would be impossible were...
Thorne’s conversionoccurred in a hotel room in Washington, D.C., in 1975. Weiss had invited him to speak to a panel ofNASAscientists. The evening before the meeting, the two men got to talking. “I don’t remember how it happened, but we shared the hotel room that night,” Weiss ...
Due to the low solubility of NF3in water (1.43x 10-5mole fraction at 1 atm partial pressure of NF3and 22°C) and its non-reactivity with water under normal conditions, the environmental hazards of an NF3leak at sea, or in coastal waters during shipment, are minimal. Any large release ...
