ii. 
Explanation:
Isoelectric species are the species which have same number of electrons.
From the given options:-
are the isoelectric species.
All the three species have same number of electrons which is equal to 6.
Carbon has 6 electrons.
has 6 electrons.
has 6 electrons.
A low electronegativity
Explanation:
Potassium is a metal that is expected to have a very low electronegativity value.
Electronegativity is the relative tendency by which an atom attracts valence electrons in a chemical bond.
Potassium is an element in the first group on the periodic table.
The common trend is that electronegativity increases from left to right and decreases down a group.
- Potassium as metal will prefer to lose electrons rather than attracting because that will make it achieve the octet configuration that will ensure its stability.
- This is why it will have low electronegativity.

Is there any more info lol
But from thinking I got A=DH^2*BC
Boiling Water is a physical change. When water gets to a certain temperature, it's boiling point starts.
The correct answer is 124 ✌
