    A. When a 3.28 g sodium bicarbonate tablet was dissolved in vinegar, 0.68 g of CO2 was produced. Use the stoichiometry NaHCO3(aq) + HC2H3O2(aq) → CO2(g) + H2O(l) + NaC2H3O2(aq) to calculate the amount (moles) of NaHCO3 consumed. B. Assume all the NaHCO3 consumed originated from the tablet. Calculate the mass of NaHCO3 in the tablet. C. Based on your answer on B, calculate the mass percent on NaHCO3 contained in the tablet.

    When H2CO3 forms as a product in the reaction with acetic acid (CH3COOH) in vinegar and HCO3 in baking soda, bubbles are formed. Those bubbles are from H2CO3 reacting (being removed from the solution) to generate water and CO2. Why does this removal of H2CO3 (product) shift the reaction Rate fwd < Raterev, so the reaction will shift to make more reactants To B Rate fwd > Raterev, so the reaction will shift to make more reactants o C Rate...
