A sample of nitrogen gas occupies a volume of 2.00 L at 756 mm Hg and 0.00°C. The volume increases by 2.00 L and the
temperature decreases to 137 K What is the final pressure
exerted on the gas?

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
