Question

Classify the elemental reagents in the given reactions as oxidizing or reducing agents. Drag the appropriate items to their respective bins. View Available Hint(s)F2 + H2 → 2HF

2Mg + O2 → 2MgO

Drag the appropriate items to their respective bins.

F2 O2 Mg H 2

OXIDIZING AGENT REDUCING AGENT

Here is a more complex redox reaction involving the permanganate ion in acidic solution:

5Fe2+ + 8H+ + MnO4- → 5Fe3+ + Mn2+ + 4H2O

Classify each reactant as the reducing agent, oxidizing agent, or neither.

Drag the appropriate items to their respective bins.
Fe2+ MnO4- H+

oxidizing agent reducing agent neither

Answer 1

Step-by-step explanation:

An oxidizing agent also called an oxidant or an oxidizer, is a substance that has the ability to oxidize other compounds or elements. They also accept or gain one or more electrons from other species in a chemical reaction.

Likewise, a reducing agent also called a reductant or reducer, is a substance that has the ability to reduce other compounds or elements. They also lose electrons to other species.

F2 + H2 → 2HF

Half ionic equations

F2(aq) + 2e- --> 2F-(aq)

H2(aq) --> 2H+(aq) + 2e-

2Mg + O2 → 2MgO

Half ionic equations

2Mg(aq) --> 2Mg2+(aq) + 4e-

O2(aq) + 4e- --> 2O2-(aq)

5Fe2+ + 8H+ + MnO4- → 5Fe3+ + Mn2+ + 4H2O

Half ionic equations

5Fe2+(aq) --> 5Fe3+(aq) + 5e-

MnO4-(aq) + 8H+ + 5e- --> Mn2+(aq) 4H2O
