Solution

Balanced equation:

NaHCO3 + HCl = NaCl + H2O + CO2

Sodium hydrogen carbonate + hydrochloric acid = Sodium chloride + water + carbon dioxide

For 1M solution of HCl

Moles of HCl = molarity x volume

= 1 * 0.040 = 0.040 moles

Moles of Sodium hydrogen carbonate = mass/molecular weight

= 2.93/84 = 0.03488 mol

From the stoichiometry of the reaction

1 mol of NaHCO3 reacts with = 1 mol of HCl

0.03488 mol NaHCO3 reacts with = 0.03488 mol of HCl

We have mol of HCl = 0.040 mol

Excess reactant = HCl

Limiting reactant = NaHCO3
