Answer:
yes but very little exposure
Explanation:
a gentle burial also increases an organisms chances of becoming more fossil like
I believe the correct response would be A. Energy being absorbed, as temperature increase must for instance occur for the reaction to occur, this increase in temperature for the reacting substances indicates energy being absorbed as the reaction proceeds.
Covalent bond is when there is relatively less difference in electronegativity of constituent atoms. On the other hand, ionic bond is formed when there is large difference in electronegativity of constituent atoms.
In present case, electronegativity of F is 3.98, electronegativity of C is 2.55, electronegativity of tin is 1.96 and electronegativity of potassium is 0.82.
Here, since the electronegativity difference is minimum in case of C-F, so covalent bond will be preferentially with carbon.
It must also be noted that neon is an inert gas, hence it will not form bond with F.
