For the following pairs of ions, predict the formula of the simplest compound that the ions are most likely to form.

a. as3+ and cl-

b. sn2+ and p3-

c. zn2+ and o2-

d. mn4+ and s2-

Explanation:

Formation of compound -

A compound can be formed from its corresponding cation and anion ,

firstly the cation is written which is followed by the anion .

Then the valence of the cationic portion is written next to the anion as lowercase ,

and

The valence of the anionic portion is written next to the cation as lowercase  .

From the question ,

a. As³⁺ and Cl⁻

Here ,

cation = As³⁺

anion = Cl⁻

The compound formed by using the above information as,

compound = AsCl₃

b. Sn²⁺ and P³⁻

cation = Sn²⁺

anion = P³⁻

The compound formed by using the above information as,

compound = Sn₃P₂

c. Zn²⁺ and O²⁻

cation = Zn²⁺

anion = O²⁻

The compound formed by using the above information as,

compound = ZnO

The valence of both cation and anion is same hence , gets cancelled out .

d. Mn⁴⁺ and S²⁻

cation =  Mn⁴⁺

anion = S²⁻

The compound formed by using the above information as,

compound = Mn₂S₄ = MnS₂

it is reliable if two scientists recorded it

it was spontaneous.
