Reduction
please telll!!! plzzz​

Answer 1

Answer:

Oxidation process.............is it ok dude

Answer 2

Answer-

Here is a redox reaction in acid solution that we're going to balance:

Fe2+(aq) + MnO4-(aq) → Fe3+(aq) + Mn2+(aq)

Step A

Write the unbalanced half equations:

Fe2+(aq) → Fe3+(aq) (oxidation)

MnO4-(aq) → Mn2+(aq) (reduction)

Step B

Balance each half reaction.

Iron Half Reaction: To balance this equation, we simply need to add an electron to the right side of the equation.

Fe2+(aq) → Fe3+(aq)) + e-

Permanganate Half Reaction: We add water to the right to balance the four oxygens on the left.

MnO4-(aq) → Mn2+(aq) + 4H2O

Next, to balance the eight hydrogens in the water, we add 8H+(aq) on the left.

MnO4-(aq) + 8H+(aq) → Mn2+(aq) + 4H2O

Now, looking at the equation above, we can see the charges are unbalanced on the left vs the right side. The overall charge on the left is +7 and on the right is +2. To balance the charge, we need to add five electrons to the left side of the equation.

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

Step C

Multiply the half equations by appropriate numbers so they each contain the same number of free electrons on each side. In this case, we must multiply the iron reaction by 5.

Step D

Add the half reactions. The electrons on each side cancel to give the overall reaction:

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