The first step in the reaction of Alka-Seltzer with stomach acid consists of one mole of sodium bicarbonate (NaHCO3) reacting with one mole of hydrochloric acid (HCI) to produce one mole of carbonic acid (H₂CO3), 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 NaHCO3 and 8 mol HCI. moles of carbonic acid : Which of the two reactants limits the number of moles of H₂CO3 that can be made? NaHCO3 HCI How much excess reactant remains after the reaction? excess reactant : mol mol
