Question

The formula of Dolomite is:
A. $MgC{O_3}.CaC{l_2}$
B. $MgC{O_3}.CaC{O_3}$
C. $MgC{O_3}.CaS{O_4}$
D. $MgC{l_2}.CaC{O_3}$

Answer 1

Hint: The solid substances that occur in earth’s crust in combined or free state and are extracted economically, these solid substances are known as minerals. Dolomite is a mineral composed of calcium magnesium carbonate

Complete step by step answer:
In nature some solid substances are present which are composed of many elements combined together and some are composed of the same type of elements in nature, these solid substances are known as minerals. Some elements form minerals of their own, some of the examples are gold, silver, platinum, etc., these minerals are called as native minerals, because they are less reactive and do not combine with other elements.
Every mineral has their own identity, the minerals are identified on the basis of colour, luster, stiffness, density and many other physical properties. Each mineral has a unique set of physical properties.
Dolomite is a mineral. It is an anhydrous carbonate mineral composed of calcium magnesium carbonate. The chemical formula of the dolomite is $CaMg{(C{O_3})_2}$ . The other way of representing this chemical formula of dolomite is $MgC{O_3}.CaC{O_3}$ . The word dolomite is also used for the rocks containing dolomite minerals.
The dolomite has many industrial uses and it is an important part of some industrial processing. Dolomite is the source of magnesium oxide or magnesia. The chemical formula of magnesium oxide is $MgO$ . Dolomite is the basic ingredient in the production of ceramics, glass and bricks.

So, the correct answer is Option B .

Note:
The dolomite mineral is very rare in nature. It is used in glass and ceramics industries and it is also an ornamental rock. The dolomite mineral is the source of magnesia or we can say magnesium oxide. The pink form of dolomite is rarely found and it is very costly also.
