As long as the heat capacity is Cp=(7/2)R, one mole of gas is adiabatically compressed at 25 degrees in the piston and cylinder device to 7 bar from a state of 2 bar. This process is irreversible and requires 35% more work than the reversible insulation process from the initial state to the same final pressure state. What is the entropy change of this gas?

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
