Nitric acid, which is among the top 15 chemicals produced in the United States, was first prepared over 1200 years ago by heating naturally occurring sodium nitrate (called saltpeter) with sulfuric acid and collecting the vapors produced. Calculate ΔH°rxn for this reaction. ΔH°f [NaNO3(s)] = –467.8 kJ/mol; ΔH°f [NaHSO4(s)] = –1125.5 kJ/mol; ΔH°f [H2SO4(l) = –814.0 kJ/mol; ΔH°f [HNO3(g)] = –135.1 kJ/mol NaNO3(s) + H2SO4(l) → NaHSO4(s) + HNO3(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)
