Oxygen and the halogens are very reactive elements and are likely to undergo coination reactions with other elements. When a metal undergos a coination reaction with oxygen, a metal oxide is formed (similarily, a metal halide is formed if reacted with one of the halogens). You see the products of this type of reaction whenever you see rust.

02.04.2020· Calcium carbonate reacts with hydrochloric acid to form calcium chloride, water and carbon dioxide. The reaction between these two compounds requires two parts hydrochloric acid to one part calcium chloride. This reaction is fairly rapid and energetic at high concentrations, in large part due to the high affinity of calcium ions for chloride ions.
Reactive metal - When a metal atom can loose electrons easily to form positive ions, it reacts rapidly with other substances .. 4. Reaction of metals with Salt Solutions – A more reactive metal displaces a less reactive metal from its salt solution.

Calcium . The chemical element Calcium (Ca), atomic nuer 20, is the fifth element and the third most abundant metal in the earth’s crust. The metal is trimorphic, harder than sodium, but softer than aluminium.A well as beryllium and aluminium, and unlike the alkaline metals, it doesn’t cause skin-burns. It is less chemically reactive than alkaline metals and than the other alkaline-earth
Ammonia gas is successively oxidized to nitric oxide and nitrogen dioxide by air or oxygen in the presence of a platinum gauze alyst, which is then absorbed in water to form nitric acid.
