Question

State a reason why 'carbon cannot reduce the oxides of Na and Mg ?

Answer 1

Answer:

carbon can't reduce the oxide of Na and Mg because these are very reactive metals.

Answer 2

Answer:

This is because sodium and magnesium are more reactive than carbon. This means that carbon cannot reduce the oxides of these metals. The two metals are above carbon in the reactivity series and thus have a high affinity to oxygen than carbon does and thus cannot be reduced by it.
