Answer:The computer writes electron configurations in the form, for Co for example, [Ar]3d(7)4s(2), which we would write [Ar]3d74s2
NOTE: Write electron configurations as they appear in the periodic table in the front of you text put 4f before 5d
Explanation:
<u>Answer:</u> The partial pressure of hydrogen is 93.9 kPa.
<u>Explanation:</u>
To calculate the partial pressure of hydrogen, we will follow Dalton's Law.
This law states that the total pressure of a mixture of gases is equal to the sum of the individual pressures exerted by the constituent gases.
Mathematically,

According to the question,

We are given:

Putting values in above equation, we get:

Hence, the partial pressure of hydrogen is 93.9 kPa.
Hydrogen is 8, Oxygen is 1, and Carbon is 3
NaCl:
Na = + 1
Cl = - 1
