Calcium Carbonate
Limestone, Marble.
CaCO3 is calcium carbonate. Its other mineral names are calcite, chalk, and marble.
It is CaCO3.....it is the same as marbleFormula: CaCO3
Ca (2+) + CO3 (2-) --> CaCO3
The formula for the calcium carbonate is CaCO3. This is most commonly used in the detergents. Calcium bicarbonate has little difference in the chemical structure and the bonding otherwise it resembles calcium carbonate.
2.
Unbalanced equation is: NO2 + CaCo3 = Ca(NO3)2 + CO2
No - you do not need the 2 prefix. It is simply CaO + CO2 = CaCO3
Molar mass of CaCO3 = 66.1221g CaCO3/mole CaCO3. This means that 1 mole CaCO3 = 66.1221g CaCO3. To find the mass of 4.5 mole CaCO3, complete the following calculation: 4.5g CaCO3 X 1mol CaCO3/66.1221g CaCO3 = 0.068 mole CaCO3.
The answer is TWO (2)Na2CO3 + CaCl2 --> 2 NaCl + CaCO3
Limestone = CaCo3. Therefore :- CaCO3 --(HEAT)--> CaO + CO2 This is known as thermal decompostition.
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)
It's a 2 step reaction. CaCO3 is the Calcium Carbonate: CaO + H2O → Ca(OH)2Ca(OH)2 + CO2 → CaCO3 + H2O
