Want this question answered?
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
Ca2 is basically two Ca's so it's larger (the plus doesn't compensate)
they cannot bond together, they are separate .
Ca2+ is a cation formed by Calcium to become stable and attain the noble gas configuration of Argon. Calcium forms this cation by losing two electrons
Ca3(AsO4)2

Ca2+ and Br- obviously must form, CaBr2 Calcium bromide
An isotope of calcium
Ca^(2+) is the Calcium cation .
they cannot bond together, they are separate .

The protein that changes shape when calcium ion (Ca2+) binds to it, is the troponin. It is a regulatory protein that is a component of the thin filament.
Carbon dioxide (gas), water and Ca2+ ions.
Its a positive calcium ion that loses two electrons.
