Answer to Question #296147 in General Chemistry for cols

Question

The neutralization reaction between hydrochloric acid (HCI) and calcium hydroxide [Ca(OH) 2 ] produces calcium chloride (CaCl_{2}) 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.) number of moles of HCI(MM = 36.46 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 (MM 110.98 g/mol) formed in the reaction.

Answer 1

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

a) Mass of HCl=72.1g

b)Mass of CaCl2=47.4g
