Answer:
The most reasonable estimate for the O–S–O bond angle in hyposulfite = 106°
Explanation:
Hyposulphite (so₂²⁻) is polyatomic ion .
According to VSEPR model
Total elrctron pairs ![=\frac{1}{2} [V+X -C+A]](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B2%7D%20%5BV%2BX%20-C%2BA%5D)
V = Valence shell electrons of central element
X = No. of monovalent surrounding atoms
C = Cationic charge
A = Anionic charge
Total electron pairs
That is two bond pairs and two lone pairs
Answer:
CaO
Explanation:
CaO is the only compound that is a non-metal and a non-metal. The rest of the compounds are ionic, or metal and non-metal.
physical
It can be chemical but it's usually physical as the molecular structure doesn't change
