Unetected Air Bubble

4. If an undetected air bubble was trapped inside the gas collection tube, how would this affect your calculated percent yield? Explain your answer. The percent yield is increasing. Because as you are doing your experiment the data needs to be as accurate as it can get, and by an air bubble being trapped inside the gas tube it is going to cause some of your data to be off. More than likely the weight and by doing this it will be increasing your percent yield because it will falsely be increasing the amount of mixture you have, because the bubble is making up for mass that is not accountant for.
