The first step in the reaction of Alka-Seltzer with stomach acid consists of one mole of sodium bicarbonate (NaHCO,) reacting with one mole of hydrochloric acid (HCI) to produce one mole of carbonic acid (H,CO,), and one mole of sodium chloride (NaCl) . Using this chemical stoichiometry, determine the number of moles of carbonic acid that can be produced from 3 mol NaHCO, and 8 mol HCI. moles of carbonic acid : mol Which of the two reactants limits the number of moles of H,CO, that can be made? O NAHCO, HCI How much excess reactant remains after the reaction? excess reactant : mol
