How many moles of hydrochloric acid are present in reaction

Reference no: EM13165127

A 0.500 L solution of 7.50 M hydrochloric acid is used to neutralize a 250.0 g sample of calcium hydroxide. Calcium chloride - a chemical used to control highway dust, strengthen concrete mixes, and add flavor to foods - is produced by the reaction.

2 HCl + Ca(OH)2 → CaCl2 + 2 H2 O

a. How many moles of hydrochloric acid are present in the reaction?
b. How many moles of calcium hydroxide are present in the reaction?
c. Is there enough hydrochloric acid to neutralize all of the calcium hydroxide?
d. How many moles of excess reagent are left over?
e. What is the theoretical yield of calcium chloride?
f. If 187 g of calcium chloride were obtained after the neutralization was complete, what was the percent yield?
