- $A_2(BC_3)_2$
- $A_3(BC_4)_2$
- $A_3(B_4C)_2$
- $ABC_2$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In $A_3(BC_4)_2 3 x$ oxidation number of $A + 2$ [oxidation number of $ B + 4 x$ oxidation number of $C$ ] = 0
$ \, \, \, \, \, \, \, \, \, 3 x (+2) + 2 [5 + 4 x (-2)] = 0$
$ \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, 6 + 2 [-31] = 0 $
$ \, \, \, \, \, \, \, \, \, 3 x (+2) + 2 [5 + 4 x (-2)] = 0$
$ \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, \, 6 + 2 [-31] = 0 $

Classification of Matter
There are two ways of classifying the matter:
(A) Physical Classification:
Matter can exist in three physical states:
- Solids - have definite volume and definite shape
- Liquids - have definite volume but not definite shape.
- Gases - have neither definite volume nor definite shape.
(B) Chemical Classification:
Based upon the composition, matter can be divided into two main types:
- Pure Substances are defined as a single substance (or matter) which cannot be separated by simple physical methods. Pure substances can be further classified as (i) Elements (ii) Compounds
- Mixtures are the combination of two or more elements or compounds which are not chemically combined together and may also be present in any proportion.
