<u>Answer:</u> The correct answer is 4, 2.
<u>Explanation:</u>
Hybridization is calculated by using the formula:
where,
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
It is given that the hybridization of a molecule is , this means that the number of electron pairs are 6. The molecular geometry of the molecule having electron pairs as 6 is octahederal.
If the molecular geometry of the molecule is square pyramidal, then it would acquire 4 electron pairs as the bonding groups and the rest pairs would be considered as lone pairs.
Hence, the correct answer is 4, 2.
Answer:
1.1: Taking Measurements. Chemists measure the properties of matter and express these measurements as quantities. A quantity is an amount of something and consists of a number and a unit. The number tells us how many (or how much), and the unit tells us what the scale of measurement is.

A food web is a system of interlocking and interdependent food chains.
A food chain is a hierarchical series of organisms each dependent on the next as a source of food.
Basically, the difference of the two is that a food web contains multiple different species in the same level that eat the animal below it's status. A food chain is one after the other.
