Calcium and sulfur will react in a 1:1 ratio to form calcium sulfide with the formula CaS.
CaS is the chemical formula of calcium sulfide.
20.0g Ca + 16.0g S = 36.0g CaS % Composition of Ca = 20.0g Ca/36.0g CaS x 100 = 55.6% Ca
The compound is lead sulfide.
Remember the general acid equation Acid plus metal gives a salt plus hydrogen. 2HNO3(aq) + Ca(s) = Ca(NO3)2(aq) + H2(g)
A white precipitate, that appears to be milky. Ca^2+(aq) + 2OH^-(aq) = Ca(OH)2 (s)
This compound is the calcium acetate.

This compound is calcium nitrate.
They form Calcium nitride a solid salt , Ca3N2.
A white precipitate, that appears to be milky. Ca^2+(aq) + 2OH^-(aq) = Ca(OH)2 (s)
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
