Explanation / Answer

first calculate the limiting reagent from given data

according to balanced reaction

2 x 36.5 g HCl reacts with 100.09 g CaCO3

12.0 g HCl reacts with 12.0 x 100.09 / 2 x 36.5 = 16.45 g CaCO3

but we have 29.0 g CaCO3 means CaCO3 is in exess

HCl is limiting reagent.

2 x 36.5 g HCl gives 110.98 g CaCl2

12.0 g HCl gives 12.0 x 110.98 / 2 x 36.5 = 18.24 g CaCl2

mass of CaCl2 produced = 18.24 g CaCl2

exess reagent = CaCO3

mass of exess reagent = 29.0 - 16.45 = 12.55 g
