<u>Answer:</u> The correct answer is 4, 2.
<u>Explanation:</u>
Hybridization is calculated by using the formula:
![\text{Number of electron pairs} =\frac{1}{2}[V+N-C+A]](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electron%20pairs%7D%20%3D%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D)
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.
Explanation:
The reaction between sulfuric acid, H2SO4 , and the base sodium hydroxide, NaOH , is a neutralization reaction. Na2SO4 is the salt sodium sulfate. ... For example, the reaction you've chosen is an acid-base reaction (also known as a neutralization reaction).
Answer:
Molecule
Explanation:
Because, the combination of bread and veggies make it more likely to be a molecule.
A melting point of over 700 C and a density of less than 2 g/cm3 can be observed for many group 2 elements. In this group, the density increases on moving down the group, whereas the melting point increases upto calcium and then starts decreasing.
Calcium, symbol Ca is the element with melting point around 840 C and density of 1.55 g/cm3 which is closest to the specified data range .
