Nitrous oxide, or a gas with an analogous composition, is the anhydride of hyponitrous acid, H2N202, and could be called hyponitrous anhydride. Owing to our defective notation, it cannot be called nitrous anhydride by analogy with the nomenclature employed in many other cases. Nitrous anhydride, N203, is the anhydride of nitrous acid, HN02. To adjust the nomenclature, nitrous oxide would have to be called hyponitrous oxide. While the action of water on nitrous or hyponitrous anhydride does not form hyponitrous acid, yet the dehydration of hyponitrous acid by cone, sulphuric acid forms nitrous or hyponitrous oxide ... 

Nomenclature. (Review Appendix II.) (a) HNO3 is the formula for nitric acid write the formulas for nitrous acid and lead nitrate, (b) HjP04 is the formula for phosphoric acid name the acids HjPOslHgPHOs) and H3PO2 (HPH3O2). (c) Name Mg(Cl04)2. (d) HBrOj is the formula for bromic acid write the formulas for perbromic and hypobromous acids.
