The statement that describes the 3d, 4s, and 4p orbitals of arsenic (as) based on its electronic configuration and position in the periodic table is; The 3d and 4s orbitals are completely filled, and the 4p orbital is partially filled.

The electronic configuration of arsenic is given as; 1s² 2s² 2p^(6) 3s² 3p^(6) 4s² 3d^(10) 4p³.

Now we can see that in that electronic configuration the orbitals are, s, p and D.

Now, the maximum electrons for each of the 3 orbitals are;

Maximum electrons for d orbital = 10 electrons

Maximum electrons for s orbital = 2 electrons

Maximum electrons for p orbital = 6 electrons.

Now, when we compare the maximum number of electrons for each orbital to the ones in electron configuration of arsenic, it is clear from the last 3 orbitals that the 3d and 4s orbitals are completely filled while the 4p orbital is half filled or partially filled.

ratelena [41]

This problem is providing us with the reaction whereby methane is produced from solid carbon and gaseous hydrogen, as well as its Kp and asks for the total pressure at equilibrium for a specified addition of reactants. At the end, the answer turns out to be 11.7 atm.

<h3>Chemical equilibrium</h3>

In chemistry, when a chemical reaction takes place, it proceeds until a point called equilibrium, where the concentration of all the species start becoming unchanged. Thus, we can use equilibrium expressions whenever we needed pressures or concentrations at equilibrium.

In this case, for the reaction we were given, we can write the following equilibrium expression, where the solid carbon is excluded:

$Kp=\frac{p_{CH_4}}{p_{H_2}^2} =0.263$

Which can also be written in terms of the reaction extent and the initial pressure of hydrogen:

$0.263=\frac{x}{(p_{H_2}^0-2x)^2}$

Thus, we calculate the initial pressure of hydrogen with the temperature and volume of the flask:

$p_{H_2}^0=\frac{(4.50g/2.02g/mol)*0.08206\frac{atm*L}{mol*K}*1000K}{10.0L}\\ \\p_{H_2}^0=18.3atm$

Hence, we solve for x in the equilibrium expression as follows:

$0.263=\frac{x}{(18.3-2x)^2}\\\\x_1=6.64atm\\\\x_2=12.6atm$

Where the correct value is 6.64 atm because the 12.6 atm turns out into a negative pressure for hydrogen at equilibrium. Finally, we calculate the total pressure with:

$P_T=p_{CH_4}+p_{H_2}=x+18.3-2x\\\\P_T=6.64atm+18.3atm-2*6.64atm\\\\P_T=11.7atm$
