The lab we are doing is: Determining the ENTHALPY of a Chemical Reaction.

Question

There are three reactions. Reaction 1: NaOH + HCl, Reaction 2: NaOH + NH4Cl, and Reaction 3: HCl + NH3.

I found the max temp, initial temp, and temp change of each reaction. Can you help me with Reaction 1. I can figure out the other two if I get help on Reaction 1.

My question is how do you find: (please show detailed steps, really appreciate it!)

1. q surroundings (J)=
2. q reaction (J)=
3. ∆H rxn (kJ) [per mole]
4. Using Hess's Law
5. Accepted Values ∆Hrxn (kJ) (per mole)
