(Answered) If an undetected bubble of air were trapped inside the gas

Academics

If an undetected bubble of air were trapped inside the gas collection tube, what would be its effect on the percent yield in your experiment. Would the actual yield (and thus the percent yield) be erroneously high, erroneously low, or unaffected by the bubble of air? Explain.

This was a magnesium reacting with HCL experiment. Mg wrapped in copper lowered into tube with water and Hydrochloric acid. Tube placed upside down into pail of water.
