2PbO+Crarr 2Pb +CO_(2) Which of the following statements are correct for the above chemical reaction? a) Lead is reduced b) CO_(2) is oxidized c) Carbon is oxidized d) Lead oxide is oxidized

(a) and (b)

(a) and (c)

(a), (b) and (c)

All

exothermic reaction

endothermic reaction

both A & B

we can't say

oxide of `Cu_(2)O` and sulphide of `Cu_(2)S`

suphide of `Cu_(3)S` and oxide of `Cu_(2)O`

`Cu (I) of Cu_(2)O , Cu_(2)S` and sulphide of `Cu_(2)S`

Cu (I) of `Cu_(2)S, Cu (I) ` of `Cu_(2)O`
