T/F Carbonate and sulphide ores are usually converted into oxides.

Give reasons: Carbonate and suphide ores are usually converted into oxides during the process of extraction

Sulphide ores are concentrated by froth floatation process.

T/F A sulphide ore is converted into its oxide to extract the metal.

Why are sulphide ores converted to oxide before reduction ?

Assertion : Sulphide ores are concentrated by Froth Flotation method. Reason : Cresols stabilise the froth in Froth Flotation method.

Beryllium occurs naturally in the form of beryl. The metal is produced from its ore by electrolysis after the ore has been converted to the oxide and then to the chloride.How many grams of Be(s) is deposited form a BeCl_2 solution by a current of 5.0 A that flows for 1.0 h? (Atomic weight:Be=9)

Name an oxide ore of a aluminium and carbonate ore of zinc.

T/F Carbon monoxide is a weak field ligand.
