Redox Reactions
A
$ CuO + H_2 → Cu + H_2O$
8%
B
$ Fe_2O_3 + 3CO → 2Fe + 3CO_2 $
14%
C
$ 2K + F_2 → 2KF$
32%
D
$ BaCl_2 + H_2SO_4 → BaSO_4 + 2HCl$
46%
Solution:
$BaCl_2 + H_2SO_4 → BaSO_4 + 2HCl$ is not a redox reaction as it does not involve any change in oxidation number. It is an example of double decomposition reaction.
