Enthalpy

Wednesday in class we went through a couple more enthalpy problems/calculations.  Enthalpy of formation values are tabulated and refer to the heat transfer when 1 mol of the substance is produced from its standard state elements.  The magnitude of that heat transfer is the same whether a substance is being formed from its elements or the elements are being formed from the substance, only the direction of the heat transfer (and therefore the sign of {delta}H) changes.  This is the key to calculating enthalpy of reaction using tabulated enthalpy of formation values.

Tonight at 6pm in HA113, Tri-Beta will be hosting research night.  Faculty from Biosciences, Chemistry, and Physics will give brief descriptions of their research and be available for questions.  If you're interested in doing research, this is a good opportunity to see a variety of the projects taking place on campus.
