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.

The elements are oxygen and carbon
Answer:-
Nuclear DNA is inherited from all ancestors. But mitochondrial DNA is inherited from a single lineage. The DNA inside of mitochondria (called mtDNA) unlike DNA inside the nucleus, comes from only mothers.
It is not a mixture of our parent’s DNA, and each person’s mtDNA is nearly identical to his or her mother’s mtDNA.
Thus only nDNA being more unique is more useful for identifying in forensics. In cases where nDNA is not sufficient, mtDNA is used.
The answer is B. The complete equation is C6H12O6 + 6O2 -->6H2O + 6CO2 + energy. So we can know that A and C and D is right. For B, the reaction release energy so it is exothermic reaction.
