Coal gasification converts coal into a combustible mixture of carbon monoxide and hydrogen, called coal gas, in a gasifier: H2O(D)+C(s)CO(g)+H2(g)H= ? Calculate the standard enthalpy change for this reaction from the following chemical equations: 2C(g)+O2(g)2CO(g)2H2(g)+O2(g)2H2O(g)H2O(g)H2O(g)H=222kJH=484kJH=+44kJ
