[Chem_Mod]

Hi,

For this question, you want to recognize that in the equation ∆U = q + w, q is negative because heat is being released FROM the system and w is positive because work is being done TO the system.

To set up your equation, identify the given values for q (∆H) and w (kcal). Make sure all values are in the same units (convert kcal to kJ as the final answer requires kJ) before you perform any arithmetic operation.

Hope that helps.
