Which element is oxidized in the reaction below? fe (co) 5 (l) + 2hi (g) → fe (co) 4i2 (s) + co (g) + h2 (g)

a. c?

The element which is oxidized in the reaction below

that is

Fe (Co) 5 (l) + 2 Hi (g) = Fe (CO) 4 i2 (s) + Co (g) + H2 (g) is

Fe this is because fe in Fe (CO) 5 compound move from oxidation state of Positive five (5^+) to oxidation state of positive six (6^+) in Fe (CO) 4i2 compound. fe is oxidized by Hi while Hi itself is reduced by Fe, therefore Fe act as a reducing agent
