Un medicamento corresponde a una disolución de "nafazolina" (sustancia activa) en agua purificada, en una concentración de 12% V
ratelena [41]

Answer:

12 mL

Explanation:

Según la pregunta;

V / V% concentración del fármaco = 12%

volumen de la solución = 100 ml

De;

V / V% = volumen de fármaco / volumen de solución

volumen de fármaco = V / V% × volumen de solución

volumen de fármaco = 12/100 × 100

= 12 mL

Write the condensed ground-state electron configurations of these transition metal ions, and state which are paramagnetic:
serg [7]

The ground-state electron configurations of Cd^{2+} transition metal ions are diamagnetic [Kr] 4d^{10}. The ion is diamagnetic because there all electrons are paired.

<h3>What is Diamagnetic?</h3>
  • A magnetic field repels diamagnetic materials because it induces an opposing magnetic field in them when it is applied, which produces a repelling force.
  • In contrast, a magnetic field draws paramagnetic and ferromagnetic materials together.
  • All materials experience the quantum mechanical phenomenon known as diamagnetism, which is the only source of magnetism in a material.
  • The magnetic dipoles within paramagnetic and ferromagnetic materials exert an attracting force that outweighs the modest diamagnetic force.
  • Diamagnetic materials have a magnetic permeability that is less than vacuum, or 0.
  • Although superconductors behave as strong diamagnets, diamagnetism is often a modest effect that can only be observed by sophisticated laboratory equipment.
