![]() * Some caveats: for example, aluminium will react slowly with water, if the thin aluminium oxide layer that prevents it from reacting is damaged. 28 Ni Nickel 58.693 29 Cu Copper 63.546 30 Zn Zinc 65.38 31 Ga Gallium 69.723 32 Ge Germanium 72.630 33 As Arsenic 74.922. * This graphic doesn’t contain every metal in the periodic table. Solve any question of Metals and Non metals with:. This reaction is known as single replacement reaction, where zinc metal displaces the hydrogen to form hydrogen gas and zinc chloride, a salt. Reason : The reaction between zinc and hydrochloric acid is, Zn+2HCl ZnCl 2 + H 2. Majority of metals occur naturally in compounds, which we must remove them from. Correct option is A) (A) Zinc chloride + Hydrogen. Zinc metal burns in air to form the white zinc(II) oxide, a material that tirns yellow on prolonged heating. Incompatibilities: Zinc powder can react violently with water, sulfur and halogens. Hazardous Polymerization: Will not occur. When heated, the two powders react explosively to form zinc sulfide. Zinc metal, when melted, produces zinc vapor which oxidizes and condenses in air to form zinc fume. Metallic zinc reacts with weak acids very slowly. ![]() Some metals are so unreactive they occur largely uncombined with other elements, simple to obtain. Hydrogen in moist air, zinc oxide with oxygen at high temperature. This is because they can react with the compounds in metal ores, and displace the metals, aiding with their extraction. Carbon and hydrogen are also shoehorned in between entries in the list, despite being non-metals. Copper sulfate + zinc → zinc sulfate + copper Magnesium sulfate + zinc → NO REACTION The reactivity series also gives us an insight into why different metals are extracted from their ores in different ways. A new paper by Virginia Commonwealth University researcher Puru Jena, Ph.D. Conversely, if we react a metal with another metal lower in the series, no reaction will take place. The more reactive metal will take the place of the less reactive metal in the compound. If a metal compound reacts with a metal that’s above it in the reactivity series, a displacement reaction will occur. Uses of this: * predict the outcome of certain chemical reactions. Transition metals are much less reactive Gold and platinum have little in the way of chemical reaction. Closely followed by the marginally less reactive group 2 metals. Metal displacement: Zn + CuSO 4 ZnSO 4 + Cu Halogen displacement: Cl 2 + 2NaBr 2NaCl + Br 2 Displacement reactions can be observed. Metals have a range of reactivities: Videos: the classic alkali metals in water demonstration The reactivity series offers a ranking of the metals in order of their reactivity. The more reactive element displaces the less reactive one from its compound. The text below has been excerpted from Compound Chemistry Student handout: Reactivity Series of Metals (PDF) This graphic places a selection of common metals into order of reactivity, as well as showing their reactions with air, water and steam.
