The change directly from solid to gas is called sublimation
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, 
![\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.
Answer:
Visible Spectrum/Electromagnetic spectrum
Explanation:
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye.
<span>They are not seen in nature because they are always combined with something to make something else.</span>
Mass % of NaCl = 0.9 % (m/v)
Density of 0.9 % NaCl is about 1.0 g/mL
Volume of NaCl in mL :

= 11.25 mL NaCl
