Answer to Question #252895 in General Chemistry for Kyle

Question

The neutralization between hydrochloric acid (HCI) and calcium hydroxide [CA(OH2)] produce calcium chloride (CaCl2) and water.

HCI(aq)+CA(OH2(s) H2O(I)+CaCl2(aq)

If 0.75 grams of Ca(OH2) is used int the reaction, determine the following:

A. Balance the given equation

B. Number of moles of HCI(MM=36.46g/mol) needed to completely react with CA(OH2). The molar mass of Ca(OJ2) is 74.10g/mol.

C. Mass of VaCl2 (MM=110.98g/mol) formed in the reaction.

Answer 1

2HCl + Ca(OH)2 -> CaCl2 + 2H2O
