CaCO3 also known as limestone.
Ca2S2
CaS.
Ca(OH)2
Ca(CO3)2
Ca2+ and Br- obviously must form, CaBr2 Calcium bromide
Ca2(Mg, Fe)5[(OH, F)|Si4O11]2
CaS
Zn(OH)2
Ca(OH)2 + 2HCl ---------> CaCl2 + 2H2OIonic Ca2+ + 2OH- + 2H+ +2Cl- -----------> Ca2+ +2Cl- + H2ONet Ionic: H+ + OH- -----------> H2O
Ca2+ and Br- obviously must form, CaBr2 Calcium bromide
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
Ca2(Mg, Fe)5[(OH, F)|Si4O11]2
Ca(NO2)2
Ca3(AsO4)2
The chemical formula for calcium hydroxide is Ca(OH)2. It consists of one calcium ion (Ca2+) and two hydroxide ions (OH-). The balance of charges is achieved by the two negative charges from the hydroxide ions balancing the positive charge from the calcium ion.
Ca2+(aq)
CaS
For example a calcium phosphate as Ca3(PO4)2.
Ca2 is basically two Ca's so it's larger (the plus doesn't compensate)
This is the net ionic equation for the formation of calcium hydroxide, Ca(OH)2 precipitate from soluble calcium ions and soluble hydroxide ions.
Only Be(OH)2.
