The fizz produced when an Alka-Seltzer® tablet is dissolved in water is due to the reaction between sodium bicarbonate (NaHCO3) and citric acid (H3C6H5O7): 3NaHCO3(aq)+H3C6H5O7(aq)→3CO2(g)+3H2O(l)+Na3C6H5O7(aq) In a certain experiment 1.20 g of sodium bicarbonate and 1.20 g of citric acid are allowed to react. How many grams of the excess reactant remain after the limiting reactant is completely consumed?
