Show your work for each step. Page 1 of 3
Write the balanced equation for reaction A – the reaction between sodium bicarbonate and hydrochloric acid. 2(g) Using mass-to-mass stoichiometry, calculate the theoretical yield of NaCl for reaction A. Use your initial mass of sodium bicarbonate reactant as a starting point, along with the relevant mole ratio from the balanced equation to perform this calculation. Calculate your percent yield of sodium chloride product. Reaction B: Sodium Carbonate and Hydrochloric Acid Experimental Data (a) Mass of evaporating dish + watch glass 47.731 g (b) Mass of evaporating dish + watch glass + sodium carbonate 48.031 g (c) Mass of sodium carbonate used 0.300 g (d) Mass of evaporating dish + watch glass + sodium chloride 48.141 g
