The chemical formula of calcium sulfide is CaS; the ions are Ca2+ and S2-.
Calcium sulphide is a compund, it has the formula CaS, and is a white solid.
Calcium Sulphide is the name(word) of the substance. It chemical formula is 'CaS'. That is one atom of calcium one atom of sulphur. NB Carefukl with the nameing oif sulphur compounds. 'Sulphate' = -SO4' (Four oxygens). CuSO4 ; Copper SULPHATE) 'Sulphite' = -SO3' (Three oxygen). (CuSO3 ; Copper SULPHITE) 'Sulphide' = -S' (No oxygens). (CuS ' Copper SULPHIDE). Note the subtle change of one letter to indicate a different sulphur type compound.
Calcium sulphate is a compound. A compound is created when two or more elements are combined such as calcium and sulphide or sodium and chloride in the case of table salt.
Formula: CaS
When calcium sulphide reacts with hydrochloric acid, it forms calcium chloride and hydrogen sulphide gas. The balanced chemical equation for the reaction is CaS + 2HCl → CaCl2 + H2S. Hydrogen sulphide gas being released gives off a rotten egg smell.
Ca is the periodic symbol for Calcium. S is the periodic symbol for Sulfur. As such, CaS2 is a compound of calcium and sulfur.
Calcium chloride consists of calcium ions (Ca2+) and chloride ions (Cl-).
The compound calcium sulfide is made up of calcium (Ca) and sulfur (S) elements.
A mole of calcium has 6.022 X 1023 calcium ions.
The formula for calcium sulfide is CaS. It consists of one calcium ion (Ca2+) and one sulfide ion (S2-).
