Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air.Its physical and chemical properties are most similar to its heavier
nitric acid + calcium → calcium nitrate + hydrogen The salt that is produced depends upon which acid and which metal react. The following table provides a summary of the name of the salt produced by different reactions between acids and metals. Hint
(a) Calcium chloride, used to melt ice on roads, consists of two elements, calcium and chlorine, in a fixed mass ratio. (b) Sulfur consists of sulfur atoms coined into octatomic molecules. (c) Baking powder, a leavening agent, contains 26% to 30% sodium hydrogen carbonate and 30% to 35% calcium dihydrogen phosphate by mass.
In both cases the zinc recoines with oxygen and zinc oxide is produced, which can be reused in the solar reactor to produce zinc once more. (Click on chart at right to enlarge.) In essence, the process stores solar energy in a transportable metal carrier that then can release the energy as …
