Answer to Question #240154 in General Chemistry for Hazel

Question

The neutralization reaction between hydrochloric acid (HCI) and calcium hydroxide [Ca(OH)2] produces calcium chloride )CaCl2) and water.

2hCl(aq) + Ca(OH)2(s) 🠖 2H2O(l) + CaCl2(aq)

If 0.75 grams of Ca(OH)2 is used in the reaction, determine the following:

a. Mass of HCl (MW=36.64 g/mol)needed to completely react with Ca(OH)2. The molar mass of Ca(OH)2 is 74.10 g/mol.

b. Mass of CaCl2 is (MW=110.98 g/mol) formed in the reaction.

Answer 1

a) Mass of HCl=72.1g

b)Mass of CaCl2=47.4g
