Metals with lower reduction potentials reduce the hydrogen ion in dilute acids to produce hydrogen gas and metal salts. B. 2Al (s) + 3H 2 O (g) → Al 2 O 3 (s) + H 2 (g) 3Fe (s) + 4H 2 O (g) → Fe 3 O 4 (s) + H 2 (g) Reaction of Metals: Least Reactive Metals with Water . Nonmetals such as carbon (C) react with oxygen forming nonmetal oxides, most of them are known as Acidic oxides. Therefore covalent compound is obtained. When they dissolve in water they form acids. Watch Reaction of Metals With Water, Acids & Bases Videos tutorials for CBSE Class 8 Science. Some water-reactive substances are also pyrophoric, like organometallics and sulfuric acid, and should be kept away from moisture. Physical nature : solid and hard due to strong force of attraction. In each reaction, hydrogen gas is given off and the metal hydroxide is produced. Ca + 2H 2 O → Ca(OH) 2 + H 2. A more active metal will react more readily with water than a less active metal. Related Questions to study. Reaction of non-metals with oxygen If a non-metal takes part in a chemical reaction with oxygen it forms an oxide.

Generally, non-metals are not lustrous. Non-metals do not react with water (or steam) to evolve Hydrogen gas. The solution of oxides of … Non-metals are also called electronegative elements because the non-metal atom form negatively charged ion by accepting electrons. When steam is passed over magnesium metal, magnesium oxide and hydrogen gas are formed. Not all metals react with water. Reaction of Metal with Water Metals + Water Metal Hydroxide + Hydrogen Example Sodium + Water Sodium Hydroxide + Hydrogen (Na) (H2O) (NaOH) (H2) Reaction of Non-Metal with Water Non Metal + Water No Reaction Example Sulphur + Water No Reaction For example, iron reacts with water slowly. Because Non-metals cannot give electrons to hydrogen in water so that it can be released as H2 gas.3 Reactionwith diluteAcids Metal + Acid →Metal salt + HydrogenHClMg(s) + 2HCl(aq)→ MgCl2(aq) + H2(g)H2SO42Na(s) + H2SO2→ Na2SO4(aq) +H2(g)HNO3Metal + HNO3→ H2 gas is not displaced.Reason- HNO3 is strong oxidizing agent. 2 N a (s o d i u m) + 2 H 2 O 2 N a O H + H 2 (h y d r o g e n g a s l i b e r a t e d) ↑ Less active metals react with boiling water. Sodium Oxide and Potassium oxide. In this example, chlorine gas will react with water to form hydrochloric acid and hypochlorous acid.
