Nitrate is converted into metal oxide on heating. This metal is:

Nitrate can be converted into metal oxide on heating not above 500°C in case of:

Give Reason: a. Prior to reduction of the metal, sulphides and metal carbonates must be converted into metal oxides. b. for extracting some metals, displacement reactions are used instead of carbon to obtain metals from their oxides.

A sulphide ore is converted into metal oxide by the process of:

A sulphide ore is converted into metal oxide by the process of:

Why should the metal sulphides and carbonated ores be converted to metal oxides in the process of extraction of the metal from them?

Why should the metal sulphides and carbonates be converted to metal oxides in the process of extraction of metal from them?

Why should the metal sulphides and carbonates be converted to metal oxides in the process of extraction of metal from them?
