What is the balanced equation for calcium iodide?
Henri Moissan first isolated pure calcium in 1898 by reducing calcium iodide with pure sodium metal: CaI 2 + 2 Na → 2 NaI + Ca. Calcium iodide can be formed by treating calcium carbonate, calcium oxide, or calcium hydroxide with hydroiodic acid: CaCO 3 + 2 HI → CaI 2 + H 2 O + CO 2.
What is the balanced equation for calcium chloride and water?
Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white coloured crystalline solid at room temperature, highly soluble in water. Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl2(H2O)x, where x = 0, 1, 2, 4, and 6.
