CaCO3 2HCl forms CO2 CaCl2 H2O

Question

1.calculate the molar mass of calcium chloride produce
2.calculate the number of moles of calcium carbonate
3.calculate the mass of calcium carbonate

Answer 1

I recommend you find the + sign on your keyboard and learn to use it.
CaCO3 + 2HCl => CO2 + CaCl2 + H2O

You need to post all of the problem.
1. The molar mass of CaCl2 is 40.1+35.5+35.5 but "produced" makes no sense.
2. mols CaCO3 in what mass?
3. mass CaCO3 is what in the problem?

Answer 2

Limestone is mostly calcium carbonate(CaCO3.john wants to know how much calcium carbonate is in a sample of mass 3,5 g of limestone.to the limestone he then adds concentrated hydrochloric acid (HCl).the products that form are carbon dioxide (CO2),calcium chloride (CaCl2) and water (H2O.he measures the mass of calcium chloride produced and determines that it has a mass of 3,6g.
4.determine the number of moles of calcium carbonate

Answer 3

CaCO3 + 2HCl => CO2 + CaCl2 + H2O

mols CaCl2 = grams/molar mass = 3.6/molar mass CaCl2 = ?
Using the coefficients in the balanced equation, convert mols CaCl2 to mols CaCO3.
If you want grams CaCO3, that is mols CaCO3 x molar mass CaCO3.
