Percentage yield of acid-base reactionUsing the reaction of hydrogen chloride (hydrochloric acid) and calcium hydroxide to produce water and calcium chloride answer the following:A. How many moles of hydrochloric acid react with 0.5 moles of calcium hydroxide?B. How many grams of hydrochloric acid react with 1 mole of calcium hydroxide?C. How many grams of calcium chloride should be formed from the reactions of hydrochloric acid and calcium hydroxide?D.
