00 P and Hei 3. Considering the techniques and instrumentation used to perform these experiments, identify 2 potential sources of error if you were to repeat this experiment in the "real world". Human error is not an acceptable answer. Discuss at least two possible sources of error that could contribute to your percent error. 4. A student is performing Reaction 2 and does not completely dissolve the NaOH pellets before acquiring the final temperature. How will this affect his value for AH, and his percent error calculations?
