Answer : The electronic geometry and the molecular geometry of the molecule will be octahedral.
Explanation :
Formula used :
![\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electron%20pair%7D%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
The given molecule is, ![PF_6^-](https://tex.z-dn.net/?f=PF_6%5E-)
![\text{Number of electrons}=\frac{1}{2}\times [5+6+1]=6](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electrons%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%5B5%2B6%2B1%5D%3D6)
The number of electron pair are 6 that means the hybridization will be
and the electronic geometry and the molecular geometry of the molecule will be octahedral.
0.52164 kg of Flour
<u>Explanation:</u>
We have to convert lb (pounds) kg (kilograms), by using the conversion unit,
1 lb = 0.4536 kg
So to convert 1.15 lb into kg, we have to multiply 1.15 by 0.4536.
= 0.52164 kg of Flour
So the receipt calls for 0.52164 kg of Flour.
Answer:
the molarity of MgCl2 = 6.073 x 10^-2 M
Explanation:
Molarity = mole (n) divided by volume of solution (V) in liter = n/v
mole (n) = mass (m) divided by molecular mass (Mm) = m/Mm
n of MgCl2 = 2.891/95.3 = 0.03033 mole
v of solution = 500 ml = 0.500 L
Molarity = n/v = 0.03033/0.500 = 0.06066 M = 6.07 x 10^-2 M
Answer: Option (D) 30N
Detailed Solution:
According to Newton's second law:
F = ma --- (A)
Given:
mass = 5kg
acceleration = 6 m/s^2
F = ?
Plug all the value in equation (A)
F = (5)(6)
Ans: F = 30N
