Very simple: CaCO2 is a phantasy, CaCO3 is calcium carbonate !
Limestone is calcium carbonate(CaCO3). CaCO3 + 2HCl -------> CaCl2 + H2O + CO2
Assuming complete reaction, the molar mass of CaCO3 is approximately 100.09 g/mol. One mole of CaCO3 produces one mole of CO2. Therefore, 10 grams of CaCO3 will produce approximately 2.24 liters of CO2 at STP (22.4 L/mol).
To convert CaCO3 and CH3COOH into a double displacement reaction, you would need to first separate CaCO3 into Ca2+ and CO32- ions, and CH3COOH into CH3COO- and H+ ions in solution. The double displacement reaction would occur when Ca2+ ions react with CH3COO- ions to form Ca(CH3COO)2, a water-insoluble compound that precipitates out of solution.
The balanced neutralization reaction between hydrochloric acid (HCl) and calcium carbonate (CaCO3) is: 2 HCl + CaCO3 -> CaCl2 + CO2 + H2O
Caco-2 is a cell line commonly used in research as a model of the human intestinal epithelium. These cells exhibit characteristics similar to the absorptive cells of the small intestine, making them valuable for studying drug absorption and transport. Caco-2 cells are particularly useful for evaluating the permeability of drugs and predicting their behavior in the human body.
No such substance as 'CaCo2'. Do you mean calcium carbonate, in which case the formula is 'CaCO3'? or do you mean an alloy(mixture) of 1 part calcium(Ca) to 2 parts cobalt(Co)?
There are three oxygen atoms in CaCO2. This can be determined by looking at the formula of calcium carbonate (CaCO3) and noting that there is one less oxygen atom in the given compound.

CaCo2 Does NOT erxist. If you means calcium carbonate the formula is 'CaCO3'. As given ;- Ca is one atom of calcium Co2 is two atoms of cobalt. Calcium carbonate (CaCO3) is a compound. It is a combination of '- 1 x calcium 1 x carbon 3 x oxygen . NB When writing chemical symbols/formulae, a single letter symbol is ALWAYS a CAPITAL letter. A two letter symbols is writtem , first letter is a capital letter, and the second letter is small/lower case. Hence 'Ca' is calcium and 'Co' is cobalt.
Assuming complete reaction, the molar mass of CaCO3 is approximately 100.09 g/mol. One mole of CaCO3 produces one mole of CO2. Therefore, 10 grams of CaCO3 will produce approximately 2.24 liters of CO2 at STP (22.4 L/mol).
Perhaps you mean CaCO3 - that's calcium carbonate. CaCO2 doesn't seem to be a common compound.

The double displacement reaction would occur when Ca2+ ions react with CH3COO- ions to form Ca(CH3COO)2, a water-insoluble compound that precipitates out of solution.

The balanced chemical equation for the reaction between CaCO3 (calcium carbonate) and KCl (potassium chloride) is: CaCO3 + 2KCl -> CaCl2 + K2CO3
CaCO3(s) + 2HCl(aq) -> CaCl2(aq) + H2CO3(aq) is the balanced chemical equation H2CO3 is not stable in this form, so it splits into CO2(g) + H2O(l) Therefore the true equation will be: CaCO2(s) + 2HCl(aq) -> CaCl2(aq) + CO2(g) + H2O(l) You NIE will start like this: CaCO2(s) + 2H+(aq) + 2Cl-(aq) -> Ca2+(aq) + 2Cl-(aq) + CO2(g) + H2O(l) and will end as: 2H+(aq) + CaCO2(s) -> Ca2+(aq) + CO2(g) + H2O(l)
Calcium Carbonate (CaCO3) obviously is different than Calcium Chloride (CaCl2) as they contain different elements. Carbon and oxygen (carbonate CO3) in Calcium Carbonate. Chlorine (Cl) in Calcium Chloride. Technically, they would both be good calcium supplements.
A system which can exchange mass as well as matter with the surroundings is called anopen system.Example:- Heating of CaCo3 in an open bulb.A system which can exchange energy but not matter is called a closed system.Example:- Calcination of CaCo3 in a sealed bulb.
