What does the enthalpy of reaction measure? O A. The amount of energy required to raise the temperature of a
substance
O B. The amount of energy required to make a chemical reaction
happen
O c. The amount of energy that is used or released as heat in a
reaction
O D. The amount of energy stored in the chemical bonds of the
reactants

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)
