Identify the correct equation for the equilibrium constant K a for the weak acid dissociation of acetic acid. H C 2 H 3 O 2 ( a q ) + H 2 O ( l ) − ⇀ ↽ − H 3 O + ( a q ) + C 2 H 3 O 2 − ( a q )

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)
