Water gas, a mixture of carbon monoxide and hydrogen, is produced by treating carbon (in the form of coke or coal) with steam at high temperatures.
C(s) + H2O(g) CO(g) + H2(g)
Not all the carbon available is converted to water gas as some is burned to provide the heat for the endothermic reaction of carbon and water. What mass of carbon (give units) must be burned (to CO2 gas) to provide the heat to convert 1.00 kg of carbon to water gas?
