Question #a5e9d + Example - Socratic

Jul 02, 2016· Explanation: Calcium metal, Ca, will react with bromine, Br2, to form calcium bromide, CaBr2, a white solid. This is a redox reaction in which calcium is being oxidized, its oxidation state going from 0 to +2, and bromine is being reduced, its oxidation state going from 0 to −1. Now, I think that this reaction actually involves gaseous bromine.

burning elements in air or oxygen - chemguide

Whether a metal burns in air or oxygen depends on exactly what form it is in (a large chunk, or a fine powder, for example) and how reactive it is. The metal oxide formed is always a solid, and may simply form a layer of the oxide on the surface of the metal with no flame. Here is just a tiny selection of metals. You will meet others later on.
