Although we usually think of substances as "burning" only in oxygengas, the process of rapid oxidation to produce a flame may alsotake place in other strongly oxidizing gases. For example, wheniron is heated and placed in pure chlorine gas, the iron "burns"according to the following (unbalanced) reaction.
