Which metal is typically extracted using the Thermite process due to its high exothermic reaction with metal oxides?
Correct: B
The Thermite process utilizes aluminium powder as a reducing agent for the oxides of certain metals, particularly those metals which are less reactive than aluminium but cannot be easily reduced by carbon (e.g., chromium, manganese, iron). The reaction is highly exothermic, producing a molten metal and aluminium oxide. Aluminium, being more reactive than these metals, reduces their oxides. Sodium is extracted electrolytically, copper by its own oxide reduction, and zinc by carbon reduction.
