Mole to Mole Conversion Example: Sodium and chlorine gas react to produce sodium chloride.
How many moles of sodium chloride can be produced from 3.56
moles of sodium?

It has to be b i hope this

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.

What are the options? physical property can be color, smell, opacity, viscosity, density, infra red spectrum, melting and boiling points, attraction and repulson to magnets, etc.
