Question

What is the chemical formula of Dolomite?
1. MgSO₄.7H₂O
2. CF₂Cl₂
3. PbS
4. CaMg(CO₃)₂

Answer 1

Correct Answer - Option 4 : CaMg(CO₃)₂

The Correct Answer is CaMg(CO3)2.

• Dolomite is a mineral of calcium magnesium carbonate consisting of anhydrous carbonate, preferably CaMg(CO₃)₂.
• The term is often used for a predominantly mineral dolomite made of sedimentary carbonate rock.
• Dolostone is an alternative name often used for the dolomitic rock type.
• In the trigonal-rhombohedral system, the mineral dolomite crystallises. It forms crystals that are white, tan, green, or pink. Dolomite is a double carbonate, with calcium and magnesium ions having an alternating structural arrangement.
• It is used as an ornamental stone, an aggregate of concrete and a source of magnesium oxide, as well as for magnesium processing in the Pidgeon process.

• MgSO4.7H2O is the chemical formula of Epsom Salt(Magnesium Sulfate Heptahydrate).
• CF2Cl2 is the chemical formula of Freon(Dichlorodifluromethane).
• PbS is the chemical formula of Galena(Lead(II) Sulfide).
