If anyone gives me a wrong answer or any other bull you will be reported immediately. Did anyone do the Equilibrium lab 07.06 for Chemistry FLVS? If so I need it URGENTLY my DBA is tomorrow and I will change your writing to mine I'm very good at that I promise just PLEASE HELP ME

Density and pressure

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.

Here is the link to the all information u need i mean answer key

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
