Consider the chemical reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) to produce sodium chloride (NaCl) and water (H2O). Write a balanced chemical equation for this reaction and determine the mole ratio of NaOH and HCl required for complete reaction. If we start with 10 grams of NaOH and 20 grams of HCl, determine which is the limiting reagent, the amount of excess reagent left over, and the mass of NaCl and H2O produced.

A chemistry student wants to determine the percentage of ethanol in a sample of wine. The student takes a 50 mL aliquot of the wine, dries it, and finds the weight of the residual solids to be 0.325 g. The student then distills the rest of the wine, evaporates the distillate to dryness, and finds the weight of the residue to be 2.324 g. Using mass balance calculations, what is the percentage of ethanol in the wine sample?
