A mutation is known to be a natural process in which the DNA sequence is changed in a living organism. Genetic variation is the change in both alleles and genes. Both throughout and amongst the pop.
Reduce, reuse, recycle, compost. I think hope its helpful.

You can realize that there is a chain of 8 Cs (I bolded it).
The proper name must use the longest C chain; i.e octane.
In this case, there are 3 methyl groups attached to the 8 Cs chain, and they are at 2, 3 and 4 positions. Therefore, the name is:
2, 3, 4 trimethyl - octane
Answer : The number placed in front of should be, three (3).
Explanation :
Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.
The given unbalanced chemical reaction is,
This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of chloride and sulfate ion are not balanced.
In order to balanced the chemical reaction, the coefficient 3 is put before the , the coefficient 2 is put before the and the coefficient 3 is put before the .
Thus, the balanced chemical reaction will be,
Therefore, the number placed in front of should be, three (3).
