What is purpose of adding HCl to the CaCO3 -H2O mixture prior to dilute?
It is the only way of dissolving CaCO3. HCl + CaCO3 --> Ca2+ + H2O + CO2 In neutral water CaCO3 is insoluble.
What is the white precipitate formed when carbon dioxide is added to lime water?
Calcium carbonate, CaCO3 Ca(OH)2 + CO2 -> CaCO3
What acid would be added to limestone to form calcium chloride?
CaCO3 + 2HCl --> CaCl2 + CO2 + H2O Hydrochloric acid, of course. (HCl)
How do you determine the number of kilograms of CaCO3 needed to neutralize 500 L of 1.40 M HCl?
CaCO3(s) + 2 HCl(aq) --> CaCl2(aq) + CO2(g) + H2O(l) 500 L * (1.40 mol HCl/1 L HCl) * (1 mol CaCO3/2 mol HCl) * (100.09 g CaCO3/1 mol CaCO3) = 35031.5 g CaCO3 35031.5 g * (1 kg/1000 g) = 35.0315 kg Therefore, about 35.03 kilograms of calcium carbonate is needed to neutralize 500 liters of 1.40 M hydrochloric acid.
What gas is formed when HCl is added to Na2S?
2HCl + Na2S ---> 2NaCl + H2S

If you have the chemical equation caco3 and hcl equal cacl3 etc. are caco3 and hcl particles molecules or ions?
They are molecules.
What is the white precipitate formed when carbon dioxide is added to lime water?
Calcium carbonate, CaCO3 Ca(OH)2 + CO2 -> CaCO3
What is the Balanced equation for calcium carbonate and hydrochloric acid reacting?
CaCO3 + HCl --> CaHCO3 or with excess of HCl CaCO3 + 2HCl --> CaCl2 +CO2 + H2O

CaCO3 + 2HCl --> CaCl2 + CO2 + H2O Hydrochloric acid, of course. (HCl)

What gas is formed when HCl is added to Na2S?
2HCl + Na2S ---> 2NaCl + H2S
What products do you get when CaCl2 plus NaHCO3?
Nacl+Hcl+CaCO3
What is the equation for calcium carbonate with hydrochloric acid?
You can find a answer fromCalcium carbonate - Wikipedia
What volume of a 0.10 mol dm-3 solution of HCl is required to react with 10.0 g of CaCO3?
2 HCl + CaCO3 = CaCl2 + CO2 + H2O Therefore it takes twice as many moles of HCl to react with CaCO3 Mol CaCO3 = mass / formulae weight = 10 / 40.08 + 14.01 + 3(16.00) = 10 / 102.09 = 0.0980 mol Mol HCl = 2 x 0.0980 = 0.1959 mol Volume HCl = mol / c = 0.1959 / 0.10 = 1.9591 L Volume required to react of HCl = 1.9591 L
What happens when aluminium metal is added to dilute hcl?
Al+HCl gives AlCl3+hydrogen So aluminium chloride is formed as a result.
How many moles of HCl can 0.055 g of calcium carbonate neutralize?
First write the balanced chemical equation for this reaction CaCO3+2HCl-->CaCl2+H2O+CO2 It is clear from this equation that one mol of HCl can react with half a mol of CaCO3. Thus, one half of .025 mols CaCO3 will react with .025 mols HCl. That makes .0125 mols CaCO3.
