Some handy info:
specific heat of ice = 2.1 J/gºC, specific heat of liquid water = 4.18 J/gºC, specific
heat of steam = 2.1J/gºC, heat of fusion/solidification of water = 334 J/g, heat of
vaporization/condensation of water = 2260 J/g
When a 10.8 g sample of solid sodium hydroxide dissolves in 100.0 g of water in a
Styrofoam cup, the temperature rises from 22.6°C to 41.8° C. Calculate AH in
kJ/mol for the solution process.
-41.5 kJ/mol
-8,030 kJ/mol
-29.7 kJ/mol
-29,700 kJ/mol

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)
