CaCO3 + 2H2O = Ca(OH)2 + H2O + H2
NB The water is acting as a very weak acid. It is a very slow reaction; So you won't see anything happening.
The complete ionic equation for the reaction is: Ca^2+(aq) + 2NO3^-(aq) + 2K+(aq) + CO3^2-(aq) --> CaCO3(s) + 2K+(aq) + 2NO3^-(aq)
The equation is H2O + CO2 + CaCO3 --> Ca(HCO3)2
HCl + NaOH = H2O + NaCl is already balanced.
The balanced equation for hydrochloric acid (HCl) reacting with calcium carbonate (CaCO3) is: 2HCl + CaCO3 -> CaCl2 + CO2 + H2O.
2K(s) + 2H2O(l) = 2KOH(aq) + H2(g) The eq'n is balanced. The coefficients ( molar ratios) in order of the reation eq'n are 2:2:::2:1
The balanced equation for the reaction between hydrochloric acid (HCl) and calcium carbonate (CaCO3) is: 2HCl + CaCO3 -> CaCl2 + H2O + CO2.
The complete ionic equation for the reaction is: Ca^2+(aq) + 2NO3^-(aq) + 2K+(aq) + CO3^2-(aq) --> CaCO3(s) + 2K+(aq) + 2NO3^-(aq)
The answer is TWO (2)Na2CO3 + CaCl2 --> 2 NaCl + CaCO3
The equation is H2O + CO2 + CaCO3 --> Ca(HCO3)2
This simple equation is: 2H2 + O2 = 2H2O
The balanced equation is Ca(OH)2 + H2SO4 → CaSO4 + 2H2O.
HCl + NaOH = H2O + NaCl is already balanced.
2Na + 2H2O -> H2 + 2NaOH
The balanced equation for hydrochloric acid (HCl) reacting with calcium carbonate (CaCO3) is: 2HCl + CaCO3 -> CaCl2 + CO2 + H2O.
2Na + 2H2O -------> 2NaOH + H2
2K(s) + 2H2O(l) = 2KOH(aq) + H2(g) The eq'n is balanced. The coefficients ( molar ratios) in order of the reation eq'n are 2:2:::2:1
The correct balanced equation for the reaction between CaO and CO2 to form CaCO3 is CaO + CO2 -> CaCO3. This represents the conservation of mass with one Ca, one C, and three O atoms on both sides of the equation.
