How many lone pairs of electrons are on the central carbon atom in a Lewis Structure of CHI3?
1 answer:
There are zero lone pairs of electrons on the central carbon atom in a Lewis Structure of CHI3. The correct option is b.
Explanation:
Lone pair electrons are those valence electrons of an atom which do not take part in bonding or left after the bonds are formed.
CH
carbon is the central atom in the compound having 4 valence electrons.
Each iodine molecule has 7 valence electrons.
H has 1 valence electron.
from the Lewis structure of CH, it is seen that all four valence electrons of the carbon is involved in bonding with 3 atoms of iodine and 1 atom of hydrogen.
Thus when all valence electrons are involved in bonding no lone pair of electron is found in CH that means zero lone pairs of electrons.
The octet of the iodine, carbon and hydrogen gets completed to form the compound.

Question options:
1. It cannot be determined without knowing which man is stronger.
2. The forces are unbalanced, and net force on the cart moves it to the left.
3. It cannot be determined because one man is taller than the other.
4. The forces are unbalanced, and net force on the cart moves it to the right.
Answer:
<em>2.The forces are unbalanced, and net force on the cart moves it to the left.</em>
Explanation:
In the image, two opposite forces acting on a rolling cart. The person on the right side exerting more force (50N) toward the left than the person on the left side (10N). The more the force applying on the object, it will drag on the followed direction.
It is because the person on the right side exerting force (50N) toward the left, rolling cart will moves to the left.
