What is a balanced equation for KNO3 NaBr and CaS?
Any reaction occur between these compounds. For preparation:NaOH + HBr = NaBr + H2OKOH + HNO3 = KNO3 + H2OCaCl2 + H2S + CaS + 2 HCl
What is ca plus s?
CaS...TARD!
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'.
ca?
cas
If 20.0 grams of Ca combines completely with 16.0 grams of S to form a compound what is the percent composition of Ca in the compound?
20.0g Ca + 16.0g S = 36.0g CaS % Composition of Ca = 20.0g Ca/36.0g CaS x 100 = 55.6% Ca
Potassium bromide and calcium sulfide equation?
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 :)
What is compound Ca plus S?
Calcium and sulfur will react in a 1:1 ratio to form calcium sulfide with the formula CaS.
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).
Compound formula for Ca and S?
They form Calcium nitride a solid salt , Ca3N2.
What is the charge of CaS?
The net charge of Ca is +2
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.
