The question is incomplete, the atoms in the third period referred to in the question are shown in the image attached.
Answer:
Cl>Si>Ar
Explanation:
Electron affinity refers to the energy released when an atom accepts electron (s) to form a negative ion. It is a periodic property that shows similar trends as electro negativity.
Considering the atoms in period three given in the question; chlorine will have the most negative value of electron affinity. This owes to the fact that halogens accept electrons easily to form negative ions. Silicon in group 14 shows much less negative value of electron affinity while argon, a noble gas, does not accept electrons at all and has an electron affinity of zero KJMol-1 by standard.

Explanation:
Given that,
Diffraction grating is ruled by 900 lines/cm
The detector length is
h= 1.2cm =1.2/100= 0.012m
Short wavelength is λs= 564.6nm
Long wavelength is λl = 571.2nm
Question: how far from the grating should the screen with the detector on it be placed. x=?
Since there are 900 lines per centimeter, each line is separated by 1/900 of a centimeter.
The distance between slits is d is given as
d = 1/900 cm
d = 0.00111cm
d = 0.0000111m = 1.11×10^-5 m
Let us call the two angles θs for short-wavelength (564.6nm) and θl for long-wavelength (571.2nm). Diffraction grating is given as
d sin(θs)= mλl
sin(θs)= mλl / d
Since we are given 7th order, then m=7
sin(θs)= 7×564.6×10^-9 / 1.11×10^-5
sin(θs)= 0.3557
θs = arcsin(0.3557)
θs = 20.84°
Applying the same principle for long wavelength
d sin(θl)= mλl
sin(θl)= mλl / d
Since we are given 7th order, then m=7
sin(θl)= 7×571.2×10^-9 / 1.11×10^-5
sin(θl)= 0.3599
θl = arcsin(0.3599)
θl = 21.1°
Using trigonometry,
Then, tanθ = opposite/adjacent
Adjacent is the distance between the screen and the detector
Opposite Is the length of detector, which serves like a height
Tanθl = h/x
x= h / Tan(θl)
x = 0.012 / Tan(21.1)
x = 0.0311m
x =3.11cm

Explanation:
Formula for final volume of chamber if the partition is ruptured will be as follows.
= 1.5 + 1.5
= 3.0
As mass remains constant then the specific volume at this state will be as follows.
=
= 1.5
Now, at final temperature = 300 F according to saturated water tables.
Hence, we obtained and the state is in wet condition.
1.5 =
= 0.229
Now, the final pressure will be the saturation pressure at = 300 F
and, =
= 66.985 psia
Formula to calculate internal energy at the final state is as follows.
=
= 920.56 Btu
Therefore, we can conclude that the final pressure of water, in psia is 66.985 psia and total internal energy, in Btu, at the final state is 920.56 Btu.
