Question

Calcium chloride, CaCl2, is formed as shown by the following equation:

Ca(OH)2 + 2HCl --> CaCl2 + 2H2O

How many grams of calcium chloride are formed by the complete reaction of 37 grams of calcium hydroxide, Ca(OH)2?

PLS помогите срочно ​

Answer 1

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

n(Ca(OH)2) = m\M = 37 \74 = 0,5 моль

n(CaCl2) = n(Ca(OH)2) = 0,5 моль

m(CaCl2) = M*n = 111*0,5 = 55,5 г
