How much energy (heat) is required to convert 52.0 g of ice at –10.0°C to steam at 100°C?  specific heat of ice: 2.09 J/g·°C   ΔHfus = 6.02 kJ/mol specific heat of water: 4.18 J/g·°C   ΔHvap = 40.7 kJ/mol specific heat of steam: 1.84 J/g·°C    

For the reaction SO2(g) + NO2(g)    SO3(g) + NO(g), the equilibrium constant is 18.0 at 1,200ºC. If 1.0 mole of SO2 and 2.0 moles of NO2 are placed in a 20. L container, what concentration of SO3 will be present at equilibrium?
