Im not that sure but the equation is:The problem is that the CaS reacts with water to give Ca(OH)2 (the precipitate) and H2S (a gas), so the overall molecular equation is:
KBr (aq) + CaS (aq) + 2 H2O ---> KBr (aq) + Ca(OH)2 (s) + H2S (g)
The potassium bromide does not enter into the reaction at all.
You might list this as:
CaS (aq) + 2 H2O ---> Ca(OH)2 (s) + H2S (g)
Hpe this helps :)
I assume a double displacement reaction. At least ideally. 2KI + CaS -> K2S + CaI2
Potassium bromide can react with elements like chlorine to form potassium chloride and bromine. It can also react with sulfur to form potassium sulfide and bromine. Additionally, it can react with metals like magnesium to form magnesium bromide and potassium.
The reaction between calcium hydroxide and hydrogen sulfide forms calcium sulfide (CaS) and water. The balanced chemical equation is: Ca(OH)2 + H2S → CaS + 2H2O.
Potassium sulfide
Formula for potassium sulfide is K2S.
Calcium Sulfide(main product) and Ammonium Bromide(bi-product)
Yes, when cobalt(III) bromide reacts with potassium sulfide, it will form cobalt(III) sulfide as a solid precipitate, as cobalt(III) sulfide is insoluble in water.

The correct order from smallest to largest ionic radius is chloride ion < sulfide ion < potassium ion < calcium ion.
Examples: uranyl nitrate, sodium acetate, potassium chloride, lithium bromide, iron sulfide, copper sulfate etc.
The reaction is:BaS + K2CO3 = BaCO3(s) + K2S
Ca is the periodic symbol for Calcium. S is the periodic symbol for Sulfur. As such, CaS2 is a compound of calcium and sulfur.
K2Sthat it.
