1. Everyone used the same value for C_cal, how does this assumption affect the results of the experiment? Would this be a human, systematic or random error across the class data for part B?
2. When analyzing the data, it is assumed that the specific heat for the solution is the same as it is for water. In fact, the specific heat for this solution is lower than that of pure water. Describe how this affects the experimental q_solution.
3. How does the failure to dissolve salt entirely affect the T for the dissolution of ammonium chloride?
4. How would H_rxn change if the concentration of HCl was doubled? Explain.

This is from an enthalpy of reaction experiment using NaOH and NH4Cl
