Saturated fats have single bond between the carbon atoms, this makes them a solid at room temperature. Unsaturated fats have at least one double bond between the carbon atoms, which makes them liquid in room temperature.
Profundal
profundal zone is the coldest and deepest zone
Water can't cool at a single temperature. It must start at a higher temperature, and drop to a lower temperature in order to cool. Unless we know the other temperature, there is no way to calculate the amount of thermal energy released.
The lower the pKa<span> of a Bronsted acid, the more easily it gives up its proton. The </span>higher<span> the </span>pKa<span> of a Bronsted acid, the more tightly the proton is held, and the less easily the proton is given up.
Here we need the highest pKa, so we need to see which compound will less likely to give proton or hydrogen ion.
</span><span>Now, all Nitrogen contains a lone pair. But HALOGEN groups( F, Cl, only) being electronegative than NITROGEN [electronegativity of N=3, F=4 and Cl=3], pulls electron pair towards itself.
</span>
The more the lone pair of nitrogen is pulled, the more strong bond between N and H will become, which means less likely to give hydrogen ion.
means high Pka
C) option is the answer because it has 3 F very close to N.
Answer:
2s²2p⁴
Explanation:
Oxygen is an element on the periodic table with a total of 8 electrons. It's electronic configuration is given as 2,6.
Using the orbital notation we write as 1s²2s²2p⁴
Also, the valence electrons are the electrons in the outermost shell of an atom. These electrons mostly determine the chemical properties of an atom.
Oxygen has a total of 6 electrons in its outermost shell and it is given as 2s²2p⁴
