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. (See Study Question 83.

Not all of the carbon available is converted to water gas since some is burned to provide the heat for the endothermic reaction of carbon and water. What mass of carbon must be burned (to CO₂ gas) to provide the energy to convert 1.00 kg of carbon to water gas?

Data given in Study Question 83

When heated to a high temperature, coke (mainly  carbon, obtained by heating coal in the absence of  air) and steam produce a mixture called water gas,  which can be used as a fuel or as a starting place  for other reactions. The equation for the production  of water gas is
