CaS...TARD!
polar
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
Calcium (Ca) is element. O2 and CaO are molecules.
One possible product of each is gvien below: 1. Ca + SO3 = CaSO3 2. SbCl3 + Cl2 = SbCl5 3. N2 + 3 H2 = 2 NH3 4. S + O2 = SO2
They do not react, the Calcium cannot displace the Potassium as it is less reactive.
The reaction between calcium (Ca) and nitric acid (HNO3) will produce calcium nitrate (Ca(NO3)2) and hydrogen gas (H2). The balanced chemical equation for this reaction is: 3Ca + 8HNO3 → 3Ca(NO3)2 + 2NO + 4H2O.
You have answered the question for yourself. Calcium + Chlorine = Calcium chloride. The BALANCED reaction equation is Ca(s) + Cl2(g) = CaCl2(s)
This is the net ionic equation for the formation of calcium hydroxide, Ca(OH)2 precipitate from soluble calcium ions and soluble hydroxide ions.
The complete ionic equation for the reaction is: Ca^2+(aq) + 2NO3^-(aq) + 2K+(aq) + CO3^2-(aq) --> CaCO3(s) + 2K+(aq) + 2NO3^-(aq)

Ca(OH )2 plus sulfuric acid yields water and CaSO4.
