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.
