P refix-NONMETAL prefix-oxide. It gave examples of carbon dioxide and sulfur dioxide. I just read about non-metallic oxides in my textbook which says that non-metallic oxides are a compound formed of an oxide ion and a non-metal. That is why metals displace hydrogen from dilute acids. The IUPAC also accepts Stock´s nomenclature for these oxides, though it is better to use the stoichiometric nomenclature when all the atoms are nonmetals and Stock´s nomenclature when there are metal and non metal atoms. Nonmetals, when reacting with metals, tend to gain electrons (typically attaining noble gas electron configuration) and become anions: 3 Br 2 (l) + 2 Al (s) → 2 AlBr 3 (s) Mg(s) + + 2 HCl (aq) —–> MgCl 2 (aq) + H 2 (g). Copper metal react with hot and concentrated sulphuric acid but no hydrogen gas is produced. Nonmetals (including – to a limited extent – xenon and probably radon) usually exist as anions or oxyanions in aqueous solution; they generally form ionic or covalent compounds when combined with metals (unlike metals, which mostly form alloys with other metals); and have acidic oxides whereas the common oxides of nearly all metals are basic. Neutralisation is the reaction between an acid and a base. Al(s) + 6 HCl (aq) —-> AlCl3 (aq) + 3 H2 (g), Zn(s) + 2 HCl (aq) —-> ZnCl2 (aq) + H2 (g), Fe (s) + 2 HCl (aq) —-> FeCl2 (aq) + H2 (g). Carbon Oxides. Fe,Al and Cu containers should not be used to store acidic food.
Generally non-metals do not react with acid because non-metals accept electron from other so they cannot donate Hydrogen ion to the acid with which they are reacting so there is no reaction. Non-metals have a tendency to gain or share electrons with other atoms.
