Answer: The oxygen gas has a pressure of 4 atm if my volume decreases to 1 L.
Explanation:
Given: = 2 L, = 2 atm
= 1 L, = ?
Formula used to calculate the new pressure is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the oxygen gas has a pressure of 4 atm if my volume decreases to 1 L.
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.
