Title: A 10g sample of calcium carbonate is completely converted into anhydrous calcium chloride.? Post by: iliri92 on Feb 15, 2013 What will be the mass of the anhydrous calcium chloride?
Can you kindly explain how you solve this tricky question? Thank you. Can anyone please help? Please! Title: A 10g sample of calcium carbonate is completely converted into anhydrous calcium chloride.? Post by: smmunday on Feb 15, 2013 Content hidden
Title: A 10g sample of calcium carbonate is completely converted into anhydrous calcium chloride.? Post by: michdo on Feb 15, 2013 The only 'tricky' part is in recognizing that this has nothing to do with hydrates.
CaCO3 + 2HCl ---> CaCl2 + H2O + CO2(g) You get one mol of the chloride for each mol of the carbonate starting material, so 10g x MWCaCl2/MWCaCO3 = answer. I'll let you use the calculator :-)) |
