In our lab we had to experiment with an apparatus in order to find such things as the percent of KClO_3 in the solution..
Assume that you heated your sample too rapidly and some of the sample spattered onto the rubber stopper of the test tube. Will your calculated percent KClO_3 be too high, too low, or unaffected if you finish the experiment as written? Explain.
You don't provide enough information to know what you've done in the lab.
