Question

carbon can reduce zinc oxide to zinc but not calcium oxide to calcium .why?

Answer 1

carbon is more reactive than zinc
but calcium is more reactive than carbon

Answer 2

Answer:

• Carbon is reduced “zinc oxide to zinc” but the carbon can’t reduce the “calcium oxide to calcium” because the ‘carbon is more reactive’ than the zinc but the “Calcium is more reactive than carbon” so carbon can’t displace the calcium.

• Amorphous, graphite, and diamond are the three types of carbon found freely in nature, and each type has vastly distinct characteristics.
