Answer:
Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N 2) and about 21% oxygen (O 2).
In short, Nitrogen
Heredity maybe? im not really sure, thats all i could think of
Answer : The shape and bond angle of the given molecule is, bent and
respectively.
Explanation :
In the given molecule, 'Y' is the central atom and 'X' is the neighboring atom. In the given molecule, there are 4 electron pairs that means the hybridization will be
and the electronic geometry of the molecule will be tetrahedral.
But as there are two atoms around the central atom, the third and fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent or angular and the bond angle will be,
.
Hence, the shape and bond angle of the given molecule is, bent and
respectively.
1.194 mol
