Answer to Question #290224 in General Chemistry for Rona

Question

if 0.75 grams of Ca(OH)2 is used in the reaction to determine the following:?

a. number of moles of HCl (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

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

a) Mass of HCl=72.1g

b)Mass of CaCl2=47.4g
