What is the difference between CaCO2 and CaCO3?
CaCO2 is not a valid chemical formula. The correct formula is CaCO3, which represents calcium carbonate. It is a common compound found in rocks, shells, and pearls, while CaCO2 does not exist as a known compound in chemistry.
What is the word equation for the reaction between limestone and hydrochloric acid?
Limestone is calcium carbonate(CaCO3). CaCO3 + 2HCl -------> CaCl2 + H2O + CO2
How many atoms of oxygen are there in CaCO2?
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.
What is the household chemical for CaCO2?
egg shells
What tests would you run to identify the compound in either NaCl or CaCl2?
Add a solution of Sodium carbonate, Na2CO2, to the mixture. If it is NaCl, no noticeable rxn will take place.since the least soluble product would be Na2CO2, which is still soluble. If it is CaCl2, the product would be CaCO2 (calcium carbonate). and a precipitate would be formed, very insoluble in water.
what would be the volume of CO2 (at STP) produced from the complete reaction of 10 grams of CaCO2?
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).
Which type of chemical reaction occurs in Ca plus Cl2--- CaCl2?
There is no equation for reacting CaCl2 and H2O. This is because nothing happens when these two chemicals combine because there is no reaction. If one was to add CaCl2 to H2O, he would end up with wet calcium chloride.
What is the net ionic equation for dilute hydrochloric acid with solid calcium carbonate?
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)
Dissociation equation of CaCl2?
The dissociation equation for CaCl2 in water is: CaCl2 (s) → Ca2+ (aq) + 2Cl- (aq)
What is the mass of 2.430 mole of CaCl2?
2.430 moles CaCl2 x 110.98 g CaCl2/mole CaCl2 = 269.7 grams (4 sig figs)
What does cacl2 stand for?
The name of CaCl2 is Calcium Chloride
What is the word equation for CaCo2?
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)?
