Answer to Question #155753 in General Chemistry for Zaina

Question

What is the potential energy value (inkJ / m * o * l) obtained via combining K^ + ions and Fions to form ionic bonds ? k=8.99*10^ 9 J.m/c^ 2 e = e = 1.6 * 10 ^ - 19 с Avogadro NO 1 =6.022*10^ 23 The distance between nions = 0.200 nm

Answer 1

k = 8.99 x 10⁹ N m² / C²

F= eN_A

mg = eN_A

P= mgh, therefore;

P = eN_Ah

= 1.6 x 10^-19  x 6.022 x 10²³ x (0.200 x 10^-9)

=1.92 x 10^-5

= J / mol
