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.

What happens when calcium sulphide reacts with hydrochloric acid?
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.
What is the word equation of calcium react with oxygen?
The word equation for calcium reacting with oxygen is: calcium + oxygen → calcium oxide.
What is the word equation for calcium and phosphorus?
The word equation for the reaction between calcium and phosphorus is: calcium + phosphorus → calcium phosphide.
What is the word equation for calcium oxide?
The word equation for calcium oxide is: calcium oxide + water → calcium hydroxide.

What is the word equation of calcium react with water?
Similar to Sodium and Water. Efferevescence and an alkali product . Ca(s) + 2H2O(l) = Ca(OH)2 (aq) + H2(g). NB Where sodium is a Group '1' metal , it has only ONE hydroxide attached. Calcium is a Group '2' meta; , so it has TWO hydroxides attached.
