1) The three combustion reactions are: C(s, gr) + O>(g) --> CO,(g) AH =-393.50 kJ H,(g) + ½0,(g) ->H,0(t) AH =-285.83 kJ CH4(g) + 202(g) ---> CO»(g) + 2H,O(t) AH=-890.36 kJ 2) The phrase 'enthalpy of formation' tells us this reaction is called for: C(s, gr) + 2H>(g) --> CH4(g)

Question
What is the kJ/mol of the reaction?
1) The three combustion reactions are: C(s, gr) + O2(g) ---> CO2(g) H,(g) + ½0,(g) ->H,0(t) AH = -393.50 kJ AH =-285.83 kJ CH4(g) + 202(g) ---> CÔ»(g) + 2H,0(1) AH=-890.36 kJ 2) The phrase 'enthalpy of formation' tells us this reaction is called for: C(s, gr) + 2H2(g) ---> CH4(g)
