Give example of a homogeneous mixture

Fluid illustrations incorporate unadulterated water, white vinegar, sugar water, corn oil, and blood plasma. Shockingly, homogeneous blends are not restricted to fluids, they can likewise be gases and solids. Another kind of homogeneous blend is known as a colloid.

Hello There

 An example of a homogeneous mixture is water. It seems to only have one substance, but it contains minerals and gases, but these are dissolved in the water.

I hope this helps

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.
