Apiece of lead with a mass of 14.9 grams at a temperature of 92.5 degrees celsius is dropped into an insulated container of water. the mass of the water is 165 g and its temperature before adding the lead is 20.00 degrees celsius. after adding the lead to the water, the water temperature rises to 20.20 degrees celsius. what is the specific heat of the lead?

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)
