Calculate the standard heat of formation of aluminum
sulfide given the following information?
2Al2S3(s) + 9O2(g) ->2Al2O3(s)+ 6SO2(g)
delta H of f = -3684.2kj
(The standard heat of formation : for SO2(g) -296.8kj/mol;
Al2O3(s)= -1676kj/mol; and O2(g)= 0.0kj/mol.)
2Al2S3(s) + 9O2(g) ->2Al2O3(s)+ 6SO2(g)
delta Hof = 2* delta Hof (Al2O3) + 6*delta Hof (SO2)
-2*delta Hof (Al2S3) - 9*delta Hof (O2)
-3684.2 = 2* (-1676) + 6* (-296.8) - 2*delta Hof (Al2S3) -
9*0
2*delta Hof (Al2S3) = 2* (-1676) + 6* (-296.8) + 3684.2
delta Hof (Al2S3) = -724.3 KJ/mol
Answer: -724.3 KJ/mol

Given 2Al2O3 (s) --> 4Al(s) + 3O2 (g) (standard enthalpy change= 3351.4 kJ) a) What is the heat of formation of aluminum oxide? How do I find heat of formation from standard enthalpy change? I know how to do it when I'm given enthalpy, but they aren't the same thing- correct? Also, if this question gave me delta-H, I know that the heat of formation for 4Al = 0 and 3O2 = 0 because they are elementary species. This would...
