Give reasona) Carbon can reduce zinc oxide to zinc but not calcium oxi

1.	Give reasona) Carbon can reduce zinc oxide to zinc but not calcium oxide to calcium.b) Aluminium is a reactive metal yet it is used for packing food articles. c) Alloys are used in electrical heating devices rather than pure metal.+ I need detailed explanation plsz
Answer» EXPLANATION: because carbon is less REACTIVE than CALCIUM aluminium makes a Aluminium oxide which protects the food because because the density of the ALLOY is more than the density of the other pure METALS
