The answer to your question is (C). I would work out the question for you lad, but I don't know how to do it on here.
Explanation:
<u>Answer:</u> The net ionic equation is written below.
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of ammonium carbonate and lead (II) nitrate is given as:
Ionic form of the above equation follows:
As, ammonium and nitrate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.
The net ionic equation for the above reaction follows:
Hence, the net ionic equation is written above.
Answer:
Only BF₃ is non polar.
Explanation:
The non polar molecule is one which will have zero dipole moment.
This zero dipole moment is possble if
a) the bonds are non polar (completely) and there is no lone electrons
b) the bonds are polar but the overall dipole moment cancel each other due to planar geometry of molecule
i) BF₃ : This is trigonal planar molecule. The overall dipole moment is zero due to symmetric distribution of electrons and thus dipole cancel each other.
ii) NF₃ : there is lone pair of electron and the bonds are polar.
iii) PBr₃: Again presence of lone pair of electrons and thus ssymmetric distribution of electrons
iv) BrCl₃ : The bonds are polar and molecule is not planar.
v) IF₃ : bonds are polar.
