Mentionthe Properties of Metals ? |
Answer» Solution :PHYSICAL properties of metals are : i) Metals are usually hard. ii) They are Sonorous, III) They are lustrus iv) Metals exhibit malleability and ductility v) They exhibit high tensil strength and have high densities: Roasting :It is a process in which sulphide ore is HEATED in the presence of oxygen to convert into oxide `2Zns-3O to 2ZnO + 2SO_2` Calcination : It is a process in which carbonate ore in heated in the ABSENCE of air of form OXIDES. `ZnCO_(3(s)) overset("heat")to ZnO_((s)) + CO_2` By reduction process Zn can be extracted from its ore. Reduction: `2ZnO+ C to ZnO + CO_2` |
