Daily Objective:

Students will be able to describe the heat energy transfer in reactions, predict the amount of heat energy produced or consumed in a reaction, and predict whether a reaction occurs spontaneously.

Bellwork:

A coffee-cup calorimeter initially contains 125 g of water at 24.2°C.  Potassium bromide (10.5 g), also at 24.2°C is added to the water, and after the KBr dissolves, the final temperature is 21.1°C.  Calculate the enthalpy of solution for dissolving the salt in J/g and kJ/mol.  Assume that the specific heat capacity of the solution is 4.18 J/g°C and that no heat is transferred to the surroundings or to the calorimeter.
