Calcium carbonate - Essential Chemical Industry
Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.
What Causes Calcium Deposits in the Eye? | Healthfully
Calcium deposits can form in three different places in the eye--the cornea, conjunctiva and retina. The cornea is the clear tissue on your eyeball that covers your iris and pupil. The conjunctiva is the clear merane that surrounds the white part of your eyeball and

Calcium ion | Ca+2 - PubChem
Calcium is essential for living organisms, particularly in cell physiology, and is the most common metal in many animals. Physiologically, it exists as an ion in the body. Calcium coines with phosphorus to form calcium phosphate in the bones and teeth.
The Science of Spherifiion | ChefSteps
Spherifiion relies on the ability of calcium to cause alginate to gel. Excess calcium can prevent hydration and cause the liquid to gel prematurely. So it can be problematic if a liquid already contains calcium before you add Sphere Magic or alginate. For reverse spherifiion and frozen reverse spherifiion, the solution is to avoid using hard water when preparing the setting bath.
