At high temperature carbon reacts with water to prodcue a mixture of carbon monoxide, CO and hydrogen, H_(2). C+H_(2)O overset("red heat")to CO+H_(2) CO is separted from H_(2) and then used to separtee nickel from cobalt by forming a volatile compound, nickel tetracarbonyl, Ni(CO__(3)) Ni+4CO to Ni(CO)_(4) How many moles of Ni(CO)_(4) could be obatined from the CO produced by the reaction of 75g of carbon? Assume 100% reaction and 100% recovery in both steps. |
