Your answers are correct. I love the Universal formula.
I think it would be true, hope this helped. Have a great day! :D
Answer:
The Inert Pair effect renders Pb(II) as the more stable oxidation state of lead
Explanation:
SnBr4 + PbBr2 ---> SnBr2 + PbBr4
SnBr2 + PbBr4 ---->
The Inert pair effect is mostly observed between group 15-17 in the periodic table. It leads to stability of the lower oxidation state of an element.
The reason for the Inert pair effect is that the s electrons become Inert due to poor shielding of the d and f-electrons. The Inert pair effect is a tendency of the s electrons not to participate in bonding (remain an Inert pair).
Owing to the Inert pair effect, Pb II is more stable than Pb IV
The owls in the certain area located in the picture represent a population, they are formed up as a small group of animals representing a small species.
IV. Molasses will sink because it has a greater density. The rest will float or suspend.
