Question

Calcium hydroxide reacts with hydrocloridric acid to produce calcium chloride and water. If you use 6.3mol of HCl and 2.8mol of Ca(OH)2 which is the limiting reagent in the reaction. Writ down the balanced equation, and show calculations to support your answer. Calcium hydroxide reacts with hydrocloridric acid to produce calcium chloride and water.

Explanation / Answer

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

from equation

1 mole Ca(OH)2 = 2 Mole of HCl

No of moles of Ca(OH)2   = 2.8 mole

No of moles of Hcl = 6.3 mole

limiting reagent is Ca(OH)2

nO OF MOLES OF CacL2 = 2.8 mole

molarmass of CaCl2 = 110.98 g/mol

mass of CaCl2 = 2.8*110.98 = 310.744 grams

No of moles of water produced = 2.8 mole

mass of water produced = 2.8*18 = 50.4 grams
