The balanced chemical reaction is written as:
<span>2K + F2 ---> 2 KF
We are given the amount of potassium metal to be used in the reaction. This will be the starting point for the calculation. We do as follows:
23.5 g K ( 1 mol / 39.1 g ) ( 1 mol F2/2 mol K ) ( 22.4 L / 1 mol ) = 13.46 L F2

Answer:hello
The third one is correct.
Explanation:
Because the molecules of solids can just have some little vibration in their places.
The first one is for gas so it's incorrect.
The second one is for liquid.
And finally the third one is correct.
Good luck.
D, because isotopes all have the same atomic number but different number of neutrons
