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?
