Question:medium

What is the number of moles of electrons gained by one mole of oxidizing agent in the following redox reaction?
$Zn_{(s)} + 2HCl_{(aq)} \longrightarrow ZnCl_2 + H_2$

Show Hint

Chemistry Tip: Pay close attention to the wording! The total electron transfer for the balanced equation is 2, but the question asks "per mole of oxidizing agent" ($HCl$), which cuts the ratio in half.
