🤓 Based on our data, we think this question is relevant for Professor Lee's class at BROOKLYN CUNY.
We are asked what the substance oxidized always does in an oxidation-reduction reaction.
Let us define oxidation and reduction.
Oxidation and reduction deal with the transferring of electrons between reactants. The reactant that loses electrons is oxidized, while the reactant that gains electrons is reduced.
In an oxidation-reduction reaction, the substance oxidized always
a. shows a gain of electrons
b. takes on oxygen atoms
c. becomes a charged species.
d. shows a loss of electrons
e. gives up hydrogen atoms
