If several large air bubbles entered the graduated cylinder filled with water when it was inverted into the water trough, what would the effect be on a plot of volume H2(g) vs. mass Mg?
The slope of the volume vs. mass Mg line would be higher than without any air.The intercept of the volume vs. mass Mg line would be higher than without any air.The slope of the volume vs. mass Mg line would be the same as without any air.The intercept of the volume vs. mass Mg line would be the same as without any air.
