In an experiment to develop a self-inflating balloon, citric acid and baking soda (sodium bicarbonate) are mixed to generate carbon dioxide gas.  The gas inflates the balloon. 20.0 mL of 0.50 M citric acid solution was placed into seven identical bottles.  The volume of sodium bicarbonate solution was varied as shown in the plot below. The volume of CO2 generated in the balloon was measured and plotted versus the volume of 0.50 M sodium bicarbonate solution used in each trial. Based on the graph, complete the following statements: Between 0 and 20 mL, increasing the volume of sodium bicarbonate solution causes the CO2 volume to [drop1] The maximum volume of CO2 generated is [drop2] The limiting reactant at 25 mL is [drop3]. At 25 mL, there is leftover [drop4] when the reaction is complete.
