To keep with the law of conservation of matter, determine the correct product for the following reaction: pbcl2 (aq) + 2 ki (aq) → + a) pbi2 + kcl2 b) pbi2 + 2 kcl c) 2 pbi + kcl2 d) 2 pbi + 2 kcl

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)
