Consider each of the following processes and determine if work is done by the system, work is done on the system or no work is done. N2 (g) → N2 (l) 2 Na (s) + 3 H2O (l) → 2 NaOH (aq)+ H2 (g) 2 NO (g) + O2 (g) → 2 NO2 (g) 2 CH3OH (l) + 3 O2 (g) → 2 CO2 (g) + 4 H2O (g) 4 NH3 (g) + 5 O2 (g) → 4 NO (g)+ 6 H2O (g)

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)
