Chemistry labs are never 100% correct. Human error, purity of the reactants, calibration of the instruments, accuracy of the instruments and measurements all lead to error entering the data.

Sounds like lab questions. You should be able to answer these better than me, as I was not in the lab. You might want to get your notes out or call someone else in your class who was there.
