Respuesta :
C) Each second, solid sodium chloride dissolves and solid sodium chloride recrystallizes
Answer: Each second, the amount of solid sodium chloride that dissolves equals the amount of solid sodium chloride that recrystallizes.
Explanation: Dynamic equilibrium refers to a equilibrium in which forward reaction and backward reaction proceeds simultaneously and at same rates.
[tex]NaCl(s)\leftrightarrow Na^++Cl^-[/tex]
Thus each second, NaCl dissociates to give sodium and chloride ions at the same rate as sodium and chloride ions combine back to give NaCl and in equal amounts.
