Question :-

In the reaction Pb + 2Ag+ – Pb2+ + 2Ag, the Ag+ is.

a) Reduced, and the oxidation number changes from +1 to 0.

b) Reduces and the oxidation number changes from +2 to 0.

c) Oxidized and the oxidation number changes from 0 to +1.

d) Oxidized, and the oxidation number changes from +1 to 0.

Solution :-Given Information :-Reaction ➢ Pb + 2Ag⁺ ⟶ Pb²⁺ + 2Ag To Find :-Whether Ag⁺ is:-a) Reduced, and the oxidation number changes from +1 to 0.b) Reduces and the oxidation number changes from +2 to 0.c) Oxidized and the oxidation number changes from 0 to +1.d) Oxidized, and the oxidation number changes from +1 to 0.Answer :-

Firstly let us know the meaning of Oxidation & Reduction and Oxidizing & Reducing Agent :-

Oxidation is process of loss of electron(s). Either atom or ion undergoing oxidation, is known as reducing agent.Reduction is process of gain of electron(s). Either atom or ion undergoing reduction, is known as oxidizing agent.

In this reaction, Ag⁺ gains an electron to get reduced to Ag. The oxidation number changes from +1 to 0. Therefore, Ag+ is an oxidizing agent.

Since, this possibility is given in option a). Reduced, and the oxidation number changes from +1 to 0. Hence, option a is the correct answer.

Final Answer :-Option a. Reduced, and the oxidation number changes from +1 to 0 is correct answer.

Answer from: Quest

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

$^{m}_{4}x$ and $^{m}_4y$

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

$^{m}_{5}x^{-}$

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be $^{9}_{5}be^{-}$ and $^{9}_{4}be$ .

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
