The balanced equation is: CaCl2 + H2CO3 -> CaCO3 + 2HCl. So, the coefficient needed is 2 in front of HCl to balance the reaction.

What is a example equation of double displacement reaction?

An equation that is an example of a double displacement reaction is CaCI2 + 2 NaHC03 2 NaCI + CaCO3 + H2O + C02. This equation is what you get when sodium bicarbonate mixes with calcium chloride.

What are the spectator ions in the given balanced chemical equation CaCI2(aq) plus k2CO3(aq) CaCO3 (s) plus 2 KCI (aq)?

The spectator ions are the ions that do not participate in the chemical reaction and remain unchanged on both sides. In this reaction, the spectator ions are Ca2+ and CO32- from CaCl2 and K2CO3, since they appear unchanged in the final products.


What is the balanced equation of Caci2 and Na2cO3?

What is the net ionic equation for the reaction between Na2SO2 and CaCI2?

The net ionic equation for the reaction between Na2SO3 and CaCl2 is: Na2SO3 (aq) + CaCl2 (aq) -> 2NaCl (aq) + CaSO3 (s) The spectator ions are sodium ions (Na+) and chloride ions (Cl-), while the reacting ions are calcium ions (Ca2+) and sulfite ions (SO32-), which form an insoluble precipitate of calcium sulfite.
