I'm assuming you mean the decomposition of Calcium carbonate, so:
CaCO3 ---> CaO + CO2
The overall equation is: CaCO3(s) + 2NaCl (aq) Na2CO3(aq) + CaCl2(aq),
The balanced equation is: CaCl2 + H2CO3 -> CaCO3 + 2HCl. So, the coefficient needed is 2 in front of HCl to balance the reaction.
the answer is DECOMPOSITION... and that is the answer not CaCO3
The other side of the equation K2CO3 + CaCl2 is 2KCl + CaCO3.
CaCl2 + H2CO3 = CaCO3 + 2HCl The molar ratios (coefficients) are 1:1::1:2
CaCO3 + 2HCl --> CaCl2 + H2O + CO2
CaCO3
the chemical equation for the decomposition of calcium hydrogen carbonate is given below.Ca(HCO3)2(aq) → CO2(g) + H2O(l) + CaCO3(s).It is a balance chmeical reaction.
The balanced chemical equation for the reaction between CaCO3 (calcium carbonate) and KCl (potassium chloride) is: CaCO3 + 2KCl -> CaCl2 + K2CO3
Calcium carbonate is represented by the chemical formula CaCO3. In a symbol equation, the reaction of calcium carbonate with hydrochloric acid can be written as: CaCO3 + 2HCl → CaCl2 + CO2 + H2O.
The balanced equation for the reaction between hydrochloric acid (HCl) and calcium carbonate (CaCO3) is: 2HCl + CaCO3 -> CaCl2 + H2O + CO2.
The balanced equation for potassium carbonate (K2CO3) reacting with calcium chloride (CaCl2) is: K2CO3 + CaCl2 -> 2KCl + CaCO3 This equation represents the double displacement reaction that occurs between the two compounds.
