So you would like to consider a few problems ahead of time to prepare you in advance. We will demonstrate two. The second problem is just a bit tricky. See if you can anticipate what gives! Problem 1: We will first consider the reaction of sodium hydroxide (NaOH) plus hydrochloric acid (HCl) to yield sodium chloride (NaCl) plus water (H₂O). NaOH + HCl → NaCl + H₂O Only one molecule of each reactant is needed to produce one molecule of each product. 1 NaOH + 1 HCl → 1 NaCl + 1 H₂O The atomic weights for…
