If you sketch a Lewis dot structure of I3-, you'll perceive
that the center I atom formulates two bonds, and also has three non-bonding
pairs of electrons. That's an over-all of five electron pairs - beyond an
octet. Lots of compounds disrupt the octet rule that means, but the first long-row
elements like F can't because the lower elements like iodine can use an obtainable
d-orbital to house the additional pair of electrons (sp3d hybridization), but F
just doesn't have a d-orbital that it can use.

Answer:
C. Deductive reasoning
Explanation:
Deductive reasoning is a reasoning or logical process whereby a conclusion is drawn based on the belief of multiple premises that are generally assumed to be true. It is a logical process in which one or multiple statements reaches a logical conclusion.
In the question, the statement assumed to be true is that <em>noble gases are unreactive because of their electronic structures.</em>
The conclusion thus drawn from the premise is that <em>if other elements could be made to achieve noble gases electronic structures (</em><u><em>this is the reason why they are unreactive - the fact)</em></u><em> they would be more stable.</em>
<em />
Therefore, deductive reasoning moves from a wilder reasoning to a specific (narrower) reasoning.

Answer:
Answer 9 - 100 joules energy was at the producer level
Answer 10 - Remaining energy is used in metabolism
Explanation:
Answer 9
The energy at each trophic level is only 10% of the energy at its previous trophic level.
The energy at producer level is X
% of 
Joules
Joules
Answer 10
Because the remaining 90% energy is utilized by the producer for its metabolism
