Answer:
Sis I think it happened with me but I am not able to remember if u want u can share if it happened with u
Answer:

Explanation:
,
are strong electrolytes. Hence they are fully ionized in aqueous solution.
is a sparingly soluble salt. Hence it remains undissociated in aqueous solution.
So, total ionic equation:

Net ionic equation is written by omitting spectator ions from total ionic equation.
Here,
and
ions are spectator ions as they remain present on both side of total ionic equation.
So, net ionic equation:

So, option (d) is correct.
I think it is an oxygen atom, I am not completely sure though.
Answer: The four
hybridized orbitals on Sb makes up the sigma bonds between Sb and F in antimony(iii) fluoride ,
Explanation:
According to VESPR theory:
Number of electrons around the central atom : ![\frac{1}{2}[V+N-C+A]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D)
V = number of valence electrons
N = number of neighboring atoms
C = charge on cation
A = charge on an anion
In antimony(III) fluoride ,
Antimony being central atom: V= 5,N =3,C=0,A=0
Number of electrons : ![\frac{1}{2}[V+N-C+A]=4](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D%3D4)
Number of electrons around the central atom are 4 which means that
molecule has four
hybridized orbitals.
