explain the following:
(a) carbon cannot reduce the oxides of Natural and Mg
(b) NaCl is not a conductor of electricity in solid state whereas it does conduct electricity in aqueous solution as well as in molten state
(c) iron articles are galvanized
(d) Metals like Na,K,Ca and Mg are never found in their free state in nature
The best answer would be the BRAINLIEST

since it's reduction value is less than mg (2)because it contains na+cl_ion so it conduct electricity (3)it has lower reduction potential so it is galvanised with zinc it always occur in combined state because it is highly reactive
