Question

What is the oxidized substance in the following reaction? Fe + 2HCl → FeCl2 + H2 A. Fe B. HCl C. FeCl2 D. H2

Answer 1

it's C, i think..because oxidation is loss of electrons (or increase in oxidation state)

Answer 2

The oxidation state of an uncombined element is zero.
\[Fe+2HCl \rightarrow FeCl2+H2 \]
Fe:0 because its an uncombined element.
Hydrogen is usually +1 except in metal hydrides where it is -1
Chlorine usually -1 except in compounds with O or F
