PbH4 will be formed as a result of a polar covalent bond between the H and the Pb.
Since H is more electronegative than the Pb, it is, thus, expected that the H would be able to pull the electron charge towards itself. This will result in the H being negative.
Based on this:
PbH4 would be expected to <span>have polar covalent bonds with a partial negative charges on the H atoms. </span>
A compound has to be chemically bonded, however, air is not chemically bonded.
This can be proven by freezing air. By freezing air, it yields different liquids at different temperature. Liquid nitrogen has a different boiling point than liquid oxygen.
If air was a compound, they would all have a single boiling point and a single freezing point.
Hope this helps :)
Answer:
The answer to A would be iv) 0.01 M HCL, but I'm not sure what the answer to part B is. Hope this helps.
Explanation:
But nitrogen is inert at room temperature whereas chlorine is highly reactive, the reason is: Nitrogen exists as N triple bond N at room temperature while chlorine exists as Cl single bond Cl at room temperature. Since the bond dissociation energy of triple bond is larger than that of single bond.
