For the following electron-transfer reaction:
creativ13 [48]

Answer:

1. The oxidation half-reaction is: Mn(s) ⇄ Mn²⁺(aq) + 2e⁻

2. The reduction half-reaction is: Ag⁺(aq) + 1e⁻ ⇄ Ag(s)  

Explanation:

Main reaction: 2Ag⁺(aq) + Mn(s) ⇄ 2Ag(s) + Mn²⁺(aq)

In the oxidation half reaction, the oxidation number increases:

Mn changes from 0, in the ground state to Mn²⁺.

The reduction half reaction occurs where the element decrease the oxidation number, because it is gaining electrons.

Silver changes from Ag⁺ to Ag.

1. The oxidation half-reaction is: Mn(s) ⇄ Mn²⁺(aq) + 2e⁻

2. The reduction half-reaction is: Ag⁺(aq) + 1e⁻ ⇄ Ag(s)  

To balance the hole reaction, we need to multiply by 2, the second half reaction:

Mn(s) ⇄ Mn²⁺(aq) + 2e⁻

(Ag⁺(aq) + 1e⁻ ⇄ Ag(s)) . 2

2Ag⁺(aq) + 2e⁻ ⇄ 2Ag(s)  

Now we sum, and we can cancel the electrons:

2Ag⁺(aq) + Mn(s) + 2e⁻ ⇄ 2Ag(s) + Mn²⁺(aq) + 2e⁻

The geometric arrangement of one of two or more compounds that have the same number and type of atoms but differ drastically from one another.

<h3>What is structural isomers?</h3>

The term "structural isomer," also known as a "constitutional isomer," refers to a group of two or more organic compounds that share the same chemical formula but have different structures. In spite of having the identical chemical formula, the two molecules below differ in where the methyl group is located.

The most extreme kind of isomerism is structural isomerism. As contrast to stereoisomerism, which merely differs in the relative spatial arrangement of the atoms while maintaining the identical atoms and bonding structure. The enantiomers, which have molecules that are mirror images of one another, and the cis and trans forms of 2-butene are examples of the latter.

Skeletal isomers, positional isomers (also known as regioisomers), functional isomers, tautomers, and structural topoisomers are some of the different classes of structural isomers.
