Question

What is the chemical formula for the following ionic compound; barium sulfate, Manganese(II) Fluoride?

Answer 1

To answer these types of questions you have to keep in mind that, in all compounds, the overall charge needs to add up to $0$ .
You must know the chemical formula of all the compounds.
In these compounds, both are inorganic compounds and have the white crystal solid that is insoluble and odorless in water.
Here we are going to see the chemical formula for the compounds: barium sulfate, manganese(II)fluoride.

Complete answer:
Barium sulfate:
Barium sulfate is made up $B{a_2}^ +$ and $S{O_2}^{ + 4}$ so, to obtain the overall charge to equal $0$ ,
The chemical formula is $BaS{O_4}$
Explanation:
Barium sulfate is an inorganic compound. The chemical formula of barium sulfate is $BaS{O_4}$ . It is a white crystalline solid. Which is odorless and insoluble in water. It occurs in nature as the mineral barite.
An alkaline, divalent metal. Barium sulfate is insoluble in water. It is taken by the mouth or given rectally. $(NACIO4)$
Uses of Barium Sulphate:
It is usually used in the casting of copper anode plates as a coating material.
It is also used as an agent of radiopaque.
It is used as an oil well drilling fluid of the components.
By acting as a filler for plastics it is used to increase the density of the polymer.
Used to find the pH level of the soil.

CHEMICAL PROPERTIES:

Molecular Formula	${F_2}Mn$ or $Mn{F_2}$
Synonyms	MANGANESE(II) FLUORIDEManganese difluorideManganese fluoride $(Mn{F_2})$Difluoro manganeseManganese fluorure [French].

ii) manganese (II) fluoride:
Manganese(II) fluoride is$M{n_2}^ +$ and ${F^ - }$ . To get the overall charge equal to $0$ , the formula is $Mn{F_2}$
Explanation:
Magnesium fluoride is an inorganic compound. The formula of manganese(II)fluoride is $Mn{F_2}$
The compound is a type of white crystalline as barium sulfate salt and it is transparent over a wide range of wavelengths, with commercial uses in optics that are also used in space telescopes. It occurs as the rare mineral sellaite naturally.

Uses of Magnesium (Ii) Fluoride:
Magnesium fluoride is commonly used in the ceramic industry, in the production of ceramic frits and enamels, in the nuclear industry, and for surface treatments.
And almost durable material for lenses that are used in UV and IR. They are durable and also they produce minimal aberrations.

Note:
Barium sulfate is made up $B{a_2}^ +$ and $S{O_2}^{ + 4}$ , so, to obtain the overall charge equal to $0$ , the chemical formula is $BaS{O_4}$
Barium sulfate is always insoluble in water and it also is used as a radiopaque agent to diagnose gastrointestinal medical conditions of a patient. Barium sulfate is taken rectally.
Manganese(II) fluoride is $M{n_2}^ +$ and ${F^ - }$ . To obtain the overall charge equal to$0$, the formula is $Mn{F_2}$
The compound is a white crystalline salt as barium sulfate and also it is transparent over a wide range of wavelengths, with commercial uses in optics that are also used in space telescopes. It always occurs as the rare mineral sellaite naturally.
As a durable material for lenses that are used are UV and IR. They produce minimal aberrations as they are durable.
