Your actual experimental percent of copper is probably different from the theoretical value. Assume that your experimental mass percentage of copper was 38.92%. Which of the following is the BEST explanation for why for this experiment and the experimental results we obtained? Some of the copper was accidentally poured out. O The copper was still wet. O We created mass in the experiment. O A side reaction occured.
