Simple diatomic molecules detected in interstellar space include co, cs, sio, sis, so, and no. calculate the electronegativity d
ifferences from the data given in the table below. rank these molecules in order of increasing dipole moment.
1 answer:
Since we aren't given any table, I attached a periodic table showing the electronegativities of each element. Using these values, we can move along to the solution. Take the absolute value for the difference.
CO: 3.5 - 2.5 = 1
CS: 2.5 - 2.5 = 0
SiO: 3.5 - 1.8 = 1.7
SiS: 2.5 - 1.8 = 0.7
SO: 3.5 - 2.5 = 1
NO: 3.5 - 3.0 = 0.5
The larger the difference, the greater the tendency for a dipole moment. So, the increasing order of dipole moment is: CS, NO, SiS, SO or CO, SiO.
CO: 3.5 - 2.5 = 1
CS: 2.5 - 2.5 = 0
SiO: 3.5 - 1.8 = 1.7
SiS: 2.5 - 1.8 = 0.7
SO: 3.5 - 2.5 = 1
NO: 3.5 - 3.0 = 0.5

Answer:
- 0.0249% Sb/cm
Explanation:
Given that:
One surface contains 1 Sb atom per 10⁸ Si atoms and the other surface contains 500 Sb atoms per 10⁸ Si atoms.
The concentration gradient in atomic percent (%) Sb per cm can be calculated as follows:
The difference in concentration =
The distance = 0.2-mm = 0.02 cm
Now, the concentration of silicon at one surface containing 1 Sb atom per 10⁸ silicon atoms and at the outer surface that has 500 Sb atom per 10⁸ silicon atoms can be calculated as follows:
= - 0.0249% Sb/cm
b) The concentration of Sb in atom/cm³ for the surface of 1 Sb atoms can be calculated by using the formula:
Lattice parameter = 5.4307 Å; To cm ; we have
=
=
The concentration of Sb in atom/cm³ for the surface of 500 Sb can be calculated as follows:
=
=
Finally, to calculate the concentration gradient
