2) Which atom is oxidized and which is reduced (show by assigning oxidation #'s) in the following equation: \[ \mathrm{Mg}+2 \mathrm{HCl} \leftrightarrow \mathrm{MgCl}_{2}+\mathrm{H}_{2} \] a) Which atom is oxidized (show by assigning oxidation #'s) and how many electrons is it oxidized by? b) Which atom is reduced (show by assigning oxidation #'s) and how many electrons is it reduced by? c) If the "oxidizing agent" is the molecule that serves as the source for the reduced atom, what is the oxidizing agent for this reaction? d) If the "reducing agent" is the molecule that serves as the source for the oxidized atom, what is the reducing agent for this reaction?
