Question

Sure, here's a question for the student to solve:How many molecules of Hydrochloric acid (HCl) are required to completely react with 5 molecules of Sodium Hydroxide (NaOH) according to the balanced chemical equation? The balanced chemical equation is:  NaOH + HCl → NaCl + H2O

Answer 1

According to the balanced chemical equation, one molecule of Sodium Hydroxide  NaOH  reacts with one molecule of Hydrochloric acid  HCl  to produce one molecule of Sodium Chloride  NaCl  and one molecule of Water  H2O .NaOH + HCl  NaCl + H2OSince there are 5 molecules of Sodium Hydroxide  NaOH , you will need 5 molecules of Hydrochloric acid  HCl  to completely react with them.
