in one experient, a student placed 50.0ml of 1.00molar Hcl at 25.5celsius in a coffee-cup calorimeter. to this was added 50.0ml of 1.00molar NaoH solution also at 25.5celsius. the mixture was stirred, and the temperature quickly increase to a maximum of 32.2 celsius. what is the energy evolved in kilojoules per mole of Hcl?
qrxn = mcdeltaT.
You know m, c, and delta T which allows you to calculate q for the reaction. That is for 50 mL x 0.1 M = 5 millimoles or 0.005 moles. Convert to kJ/mole
