What is AGsystem for the system that is described by the following data?
AHsystem = -232 kJ, T = 293 K, ASsystem = 195 J/K
AGsystem = AHsystem - TASsystem
O-289 kJ
O -175 kJ
O 256 kJ
O 56,903 kJ

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above
