What is the reduction half-reaction for the equation below?
Katen [24]

Answer:

MnO_4^-+8H^++5e^-\rightarrow Mn^{2+}+4H_2O

Explanation:

Hello there!

In this case, since redox reactions are characterized by the presence of a reduction reaction, whereby the oxidation of the element decreases, and an oxidation reaction whereby the oxidation of the element increases.

In such a way, for the given chemical equation, we can see Fe is increasing its oxidation state from 2+ to 3+, which means it is oxidized. On the flip side, Mn is being reduced from 7+ (MnO₄⁻) to 2+ and this, the reduction half-reaction is:

MnO_4^-+8H^++5e^-\rightarrow Mn^{2+}+4H_2O

Whereas five electrons are carried.

Regards!

What is the formula unit for a compound made from Pb4+ and oxygen?
dem82 [27]

Answer : The formula unit of compound will be, PbO_2

Explanation :

As we know that one atom of oxygen contains (2-) charge and one atom of lead contains (4+) charge. So, to balance the of charges of lead, the 2 oxygen atoms combine with the 1 lead atom. Thus, the compound formed will be, PbO_2.

That means, when Pb^{4+} combine with oxygen that is, O^{2-}, it gives PbO_2 by the criss-cross method.

Criss cross method : It is a method of determining the chemical formula.

The formula unit is a shown below.
