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.

What are the charges for compound CaS?
In calcium sulfide (CaS), calcium (Ca) has a charge of +2, as it is an alkaline earth metal that typically loses two electrons. Sulfide (S) has a charge of -2, as it gains two electrons to achieve a stable electron configuration. Therefore, the overall charge balance in CaS is neutral, with one Ca^2+ ion combining with one S^2- ion.
What is the products of the reaction CaOs H2Ol CaOH2s?
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).
What is the formula of the compound made by combining calcium (Ca) with sulfur (S)?
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.

What is the formula of the compound Ca and S?
The compound formed from calcium (Ca) and sulfur (S) is calcium sulfide (CaS). The formula for calcium sulfide is CaS.
What is the chemical formula for Ca S?
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'.
Potassium bromide and calcium sulfide equation?
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.

What is compound Ca plus S?
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.
What is the product of the reaction between calcium hydroxide and hydrogen sulfide?
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.
Compound formula for Ca and S?
They form Calcium nitride a solid salt , Ca3N2.
What is the name of the chemical formula CaS?
Ca is the periodic symbol for Calcium. S is the periodic symbol for Sulfur. As such, CaS2 is a compound of calcium and sulfur.
What are the charges for compound CaS?
In calcium sulfide (CaS), calcium (Ca) has a charge of +2, as it is an alkaline earth metal that typically loses two electrons.
