Question

How many moles of calcium chloride are theorectically produced for the following reaction given we have 2.6 moles of HCl and 1.4 moles of Ca(OH)2?

Reaction: 2HCl + Ca(OH)2 → 2H2O + CaCl2
a. 0.7.
b. 1.0.
c. 1.3.
d. 1.4.
e. not enough information.

Answer 1

the limiting reagent is HCl

2.6 moles of HCl will react with 1.3 moles of Ca(OH)2. and since the coefficient of Ca(OH)2=CaCl2=1, 1.3 moles of CaCl2 will be produced
