State the nature and name of the substance formed by combining the
following:
i. Zinc + Copper
ii. Water + Sugar
ini. Aluminium + Sulphur iv. Iron + Chromium + Nickel
Answers
Answer:
Zinc–copper couple is an alloy of zinc and copper that is employed as a reagent in organic. An early method for the synthesis of zinc–copper couple entailed treatment of a mixture of zinc dust and copper(II).
True Solution is a homogeneous mixture of two or more materials with a particle size of less than 10-9 m or 1 nm dissolved in the solvent. A solute is a substance to be dissolved (sugar). The solvent is the one doing the dissolving (water). Here, Sugar is the solute and water is the solvent.
Aluminum sulfide or aluminium sulphide is a chemical compound with the formula Al2S3. The material is sensitive to moisture, hydrolyzing to hydrated aluminum oxides/hydroxides. This can begin when the sulfide is exposed to the atmosphere. The hydrolysis reaction generates gaseous hydrogen sulfide (H2S).
Nickel-Chromium-Iron Alloys
There are basically two groups of alloys:
Ni – Cr – Fe (with Mo and Cu) alloys with excellent corrosion resistance in specific applications. Probably the best-known is alloy 825 (UNS N08825), which offers exceptional resistance to sulphuric acid.
