1. When 3.02 g of methane burns in oxygen, 151 kJ of heat is produced. What is the enthalpy of combustion (in kJ) per mole of methane under these conditions?

2. Joseph Priestly prepared oxygen in 1774 by heating red mercury(II) oxide with sunlight focused through a lens. How much heat (in kJ) is required to decompose 1.18 mol of red HgO(s) to Hg(l) and O2(g) under standard conditions?

The element oxygen was prepared by Joseph Priestley in 1774 by heating mercury (II) oxide. HgO(s) --> Hg(l) + 1/2O2(g) ΔH° = 90.84 kJ Use the data given below to determine DS =    and the temperature, at which this reaction will become spontaneous under standard conditions. S°(Hg) = 76.02 J/K· mol S°(O2) = 205.0 J/K· mol S°(HgO) = 70.29 J/K· mol
