If you want an example then a car passing by a standing man is the best one !!
Answer: The angle between the carbon-chlorine bonds in phosgene will be 120°
Explanation: Formula used to calculate the hybridization:
![{\text{Number of electron pairs}} =\frac{1}{2}[V+N-C+A]](https://tex.z-dn.net/?f=%7B%5Ctext%7BNumber%20of%20electron%20pairs%7D%7D%20%3D%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D)
where,
V = number of valence electrons present in central atom i.e. carbon = 4
N = number of monovalent atoms bonded to central atom = 2
C = charge of cation = 0
A = charge of anion = 0
For 
![{\text{Number of electron pairs}} =\frac{1}{2}[4+2-0+0]=3](https://tex.z-dn.net/?f=%7B%5Ctext%7BNumber%20of%20electron%20pairs%7D%7D%20%3D%5Cfrac%7B1%7D%7B2%7D%5B4%2B2-0%2B0%5D%3D3)
The number of electron pairs are 3 which means that the hybridization will be
and the electronic geometry of the given molecule will be trigonal planar.
The bond angle in this electronic geometry is 120°
The structure of phosgene is attached below.
Answer:
Physical change because even though gas formation was observed, the water was undergoing a state change, which means that its original properties are preserved.
Explanation:
The gas formation seen is in fact the transition of the liquid water to a gas state, not the formation of a new gas.
