Classify these half-reactions by typing in “O” for “oxidation half-reaction,” “R” for “reduction half- reaction,” and “N” for “neither.” Upper H upper C l right arrow upper m g upper C l subscript 2. Upper m g right arrow upper M g upper C l subscript 2 plus 2 e superscript minus. 2 upper H upper C l plus 2 e superscript minus right arrow upper H subscript 2.

An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing electrons.

What are the half-reactions?

There are 2 kinds of half-reactions.

Oxidation: An species loses electrons and its oxidation number increases.

Reduction: An species gains electrons and its oxidation number decreases.

Let's classify the following half-reactions.

HCI → MgCl₂

Electrons are not exchanged and Cl, the element present on both sides, has the same oxidation number, -1. This is neither oxidation nor reduction.

Mg → MgCl₂ + 2 e⁻

Mg loses 2 electrons and its oxidation number increases from 0 to +2. This is an oxidation half-reaction.

2 HCI + 2 e⁻ → H₂

H gains 2 electrons and its oxidation number decreases from +1 to 0. This is a reduction half-reaction.

The classification for the following half-reactions is:

"N": HCI → MgCl₂
"O": Mg → MgCl₂ + 2 e⁻
"R": 2 HCI + 2 e⁻ → H₂

The question is incomplete. I believe the complete question is as follows.

Use this oxidation-reduction reaction to answer questions about half-reactions:

Mg + 2 HCl → MgCl₂ + H₂

Classify these half-reactions by typing in "O" for "oxidation half-reaction," "R" for "reduction half-reaction," and "N" for "neither."

HCI → MgCl₂

Mg → MgCl₂ + 2 e⁻

2 HCI + 2 e⁻ → H₂
