Calcium (Ca) can react with various substances, but one common reaction is with oxygen (O2) to form calcium oxide (CaO). This reaction is exothermic and produces a bright white flame. Additionally, calcium reacts with water to produce calcium hydroxide and hydrogen gas, which can be observed as bubbling. These reactions illustrate calcium's reactivity, particularly with nonmetals and water.
The reaction is: CaO(s) + H2O(l)--- --> Ca(OH)2(s) Ca(OH)2(s) is the product (at the right side of the reaction equation).
The formula of the compound formed by combining calcium (Ca) with sulfur (S) is CaS. Calcium has a +2 oxidation state, while sulfur has a -2 oxidation state. To balance the charges, one calcium atom combines with one sulfur atom, resulting in the formula CaS.
This reaction is exothermic.
This reaction is exothermic.
The reaction is endothermic.
CaS...TARD!
The compound formed from calcium (Ca) and sulfur (S) is calcium sulfide (CaS). The formula for calcium sulfide is CaS.
CaS is the chemical formula for calcium sulphide. NB The elemental letters should NOT be separated by spaces. 'Ca S' is incorrect. I should be written as ' CaS'.

The chemical equation for the reaction between potassium bromide (KBr) and calcium sulfide (CaS) is: 2KBr + CaS -> CaBr2 + K2S This is a double displacement reaction where the cations in the two reactants switch partners to form two new compounds.
When calcium (Ca) reacts with sulfur (S), they form calcium sulfide (CaS), a compound where one calcium ion is bonded to one sulfur ion through an ionic bond. The chemical formula for this compound is CaS.
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.
They form Calcium nitride a solid salt , Ca3N2.
Ca is the periodic symbol for Calcium. S is the periodic symbol for Sulfur. As such, CaS2 is a compound of calcium and sulfur.
The reaction is: CaO(s) + H2O(l)--- --> Ca(OH)2(s) Ca(OH)2(s) is the product (at the right side of the reaction equation).
(1/8 x 8) + (1/2 x 6) = 4 S^2- ions per unit cell CaS.
The balanced equation for the reaction between sulfuric acid (H2SO4) and calcium sulfide (CaS) in aqueous solution is: H2SO4(aq) + CaS(aq) → CaSO4(s) + H2S(g)
