How many ions of carbonate present in 40 grams of calcium carbonate?
caco3 (40)+(12)+3(16) =100/40 =2.5
Is calcite and calcium the same thing?
No. Calcite is calcium carbonate, CaCO3, which contains cacium ions. Calcium is the metallic element.
How many ions of calcium present in 40 grams of calcium carbonate?
9.03x10 23 ions
Why might adding calcium carbonate or sodium carbonate to acidic lakes solve the problem?
Sodium Carbonate (NACO3) and Calcium Carbonate (CACO3) are alkaline salts which neutralises the acidity of a lake. Also, once an acid is neutralized, the remaining alkaline substances will create hydroxyde OH- ions which helps elevate the pH over 7.
How can one compound both ionic and covalent bond?
Some ionic compounds contain polyatomic ions. These are ions that consist of two or more atoms held together by covalent bond like in a molecule, except that it has an overall electrical charge. One common polyatomic ion is the carbonate ion, CO32- It will combine with other ions to form ionic compounds such as calcium carbonate (CaCO3) and sodium carbonate (Na2CO3)

caco3 (40)+(12)+3(16) =100/40 =2.5
What is the name of the formula CaCO3?
The name of the chemical formula CaCO3 is calcium carbonate. Calcium carbonate is commonly found in rocks and is created when ions in hard water react with carbonate ions to create limescale. The hardness of water is measures in ppm CaCO3.
Is calcite and calcium the same thing?
No. Calcite is calcium carbonate, CaCO3, which contains cacium ions. Calcium is the metallic element.

What are metal carbonates made up of?
metal ions and carbonate ions, CO32-.Fro example:-sodium carbonate Na2CO3, 2Na+ CO32-calcium carbonate, CaCO3, Ca2+ CO32-
I was recently at the fish store and the salesman said that the reason for the high alkalinity in my tank was due to shells made of calcium. Why would Calcium be making my water more basic?
# The shells aren't made of calcium, they're made of calcium carbonate. # Calcium carbonate is the salt of a strong base and a weak acid, and is therefore weakly alkaline. I understand that you can make CaCO3 by the following process: HCO3 + CaOH => CaCO3 +H2O But once you have made CaCO3 ( a slightly alkaline salt) from the acid and base, what is happening to the CaCO3 in the H2O that is making the water more basic? In other words, how can CaCO3 have anything to do with the lone OH- ions present in the water?
What is the balanced symbol equation for calcium carbonate plus nitric acid?
CaCO3 + HNO3. NO3^- and CO3^-2 are both polyatomic ions.
What is inside calcium carbonate?
CaCO3 + H2CO3(aq) -> CaCO3 + H2CO3(aq) There is nothing to drive any sort of reaction at conditions near STP. At elevated temperatures such as would be found in a cement kiln, the calcium carbonate would decompose to calcium oxide and carbon dioxide while the carbonic acid would have long since evaporated to give water vapor and carbon dioxide.
What ions are present in water that has run over limestone?
When water runs over limestone in the presence of carbon dioxide, calcium ions and hydrogen carbonate ions pass into the water. CaCO3 + H2O + CO2 = Ca(HCO3)2 Water also self ionizes so there will also be hydrated hydrogen ions and hydroxide ions.
What is chemical structure of calcium carbonate?
Calcium carbonate would be an ionic compound composed of the cation Ca2+ and the polyatomic anion CO32-. Combining these ions in a 1:1 ratio causes the charges to balance, so the formula would be CaCO3.
Why might adding calcium carbonate or sodium carbonate to acidic lakes solve the problem?
Sodium Carbonate (NACO3) and Calcium Carbonate (CACO3) are alkaline salts which neutralises the acidity of a lake. Also, once an acid is neutralized, the remaining alkaline substances will create hydroxyde OH- ions which helps elevate the pH over 7.
How many atoms are in a molecule of lime?
Lime is calcium carbonate, which is an ionic substance and does not exist as molecules. The formula unit gives the lowest whole number ratio of ions present in the substance, which is CaCO3. There are 5 atoms in one formula unit of lime; one calcium, one carbon, and three oxygen atoms.
