How many grams of calcium in 34.5 of Ca CO 3?
34.5 g CaCO3 (1 mole CaCO3/100.09 g)(1 mole Ca/1 mole CaCO3)(40.08 g/1 mole Ca) = 13.8 grams calcium ===============
What is the net ionic equation of Na2CO3 plus CaCl2 equals CaCo3?
Ca (2+) + CO3 (2-) --> CaCO3
What is the balanced equation for calcium hydroxide and carbon dioxide produce calcium carbonate and water?
If you are after the symbol equation it's: Ca(OH)2(aq) + CO2 --> CaCO3 The word equation is: Calcium Hydroxide + Carbon Dioxide --> Calcium Carbonate (Limewater) (Limestone)
What are the elements in CaCO3 and HCI?
Ca C O H & Cl
What is the white precipitate formed when carbon dioxide is added to lime water?
Calcium carbonate, CaCO3 Ca(OH)2 + CO2 -> CaCO3
How many Ca atoms are found in 0.50 moles of CaCO3?
0.50 moles CaCO3 (1 mole Ca/1 mole CaCO3)(6.022 X 1023/1 mole Ca)= 3.0 X 1023 atoms of calcium===================

Chemical reaction of caco3 and No2?
Unbalanced equation is: NO2 + CaCo3 = Ca(NO3)2 + CO2
What is the net ionic equation of Na2CO3 plus CaCl2 equals CaCo3?
Ca (2+) + CO3 (2-) --> CaCO3

If you are after the symbol equation it's: Ca(OH)2(aq) + CO2 --> CaCO3 The word equation is: Calcium Hydroxide + Carbon Dioxide --> Calcium Carbonate (Limewater) (Limestone)
What is the chemical formula for ca and co3?
CaCO3 is calcium carbonate.
What are the elements in CaCO3 and HCI?
Ca C O H & Cl
What is the mass percent of calcium in calcium suppleiment if 1.15g of CaCO3 is extracted from a 2.70g pill?
1.15 (g CaCO3) / 100.1 (g/mol CaCO3) =1.149*10-2 (mol Ca)1.149*10-2 (mol Ca) = 1.149*10-2 (mol Ca) * 40.08 (g/mol Ca) = 0.4604 g Ca0.4604 g Ca = 0.4604 g Ca / 2.70 g Supplement = 0.1705 * 100% = 17.1% Calcium (m%)
What is the white precipitate formed when carbon dioxide is added to lime water?
Calcium carbonate, CaCO3 Ca(OH)2 + CO2 -> CaCO3
How do you convert alkalinity as HCO3 to CaCO3?

Write a chemical equation for the solution of dolomite by carbonic acid?
Limestone = CaCo3. Therefore :- CaCO3 --(HEAT)--> CaO + CO2 This is known as thermal decompostition.
What are the chemical reactions that take place in limestone caves?
CaCO3> Ca^2+ +CO3^2- Basic CaCOO3+H^+ > Ca2+ +HCO3^- Ph dissolution CaCO3+ 2H^+ > Ca2+ + H2O + CO2 acidic Ph dissolution CaCO3+ H2O +CO2 > Ca^2+ + 2HCO3^- CO2 reacts with the atmosphere
