Summary

The reaction between NaHCO3 and HC2H3O2 is an acid-base reaction, where the weak acid HC2H3O2 reacts with the weak base HCO3-, with HC2H3O2 donating a proton. The limiting reactant is NaHCO3, as it reacts with HC2H3O2 in a 1:1 ratio and has a lower number of moles (0.0267 mol) compared to HC2H3O2 (0.0525 mol). The reaction rate slows down as the reaction proceeds due to the decrease in concentrations of the reactants, making collisions between reactant particles less likely. The reaction is driven by entropy, as the flask gets cooler, indicating an endothermic reaction, and the presence of a gas product increases the entropy. The Lewis electron-dot diagram for the HCO3- ion shows three carbon-to-oxygen bonds, with two having the same length and the third being longer, and the hydrogen atom bonded to one of the oxygen atoms. The net-ionic equation for the reaction between HNO3 and the chemical species in the sample is C2H3O2- + H3O+ → HC2H3O2 + H2O or C2H3O2- + H+ → HC2H3O2.
