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

Why are sulphide ores converted to oxide before reduction ?

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

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

Calcination is the process of converting an ore into its oxide by heating it in the limited /excess air.

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)

Calculate the weight of iron which will be converted into its oxide (Fe3O4) by the action of 14.4g of steam on it.

Suphur dioxide (SO_2) gas is produced when a certain ore is heated write the method involved in the extraction of metal from this ore.

Experimentally it was found that a metal oxide has formula M_(0.98)O . Metal M is present in M^(2+) and M^(3+) in its oxide. Fraction of the metal which exists as M^(3+) would be
