QUESTION 2: The fizz produced when an antacid tablet is dissolved in water is due to the reaction between sodium bicarbonate (NaHCO3, Mw = 84.01 g mol-') and citric acid (H3C6H507, Mw = 192.1 g mot') according to the following reaction: 3 NaHCO3(aq) + H3C6H507(aq) + 3 CO2(g) + 3 H2O(l) + Na3C6H507(aq) In an experiment 1.00 g of sodium bicarbonate and 1.00 g of citric acid are allowed to react. (a) How many moles of the excess reactant remain if the reaction is complete?​
