Answer:
9.00 atm
For total pressure, you would add all the pressures together
Noble gas configuration for Li : [He]2s¹
<h3>Further explanation
</h3>
In an atom, there are levels of energy in the shell and sub-shell
This energy level is expressed in the form of electron configurations.
Lithium with atomic number 3, then the electron configuration:
1s²2s¹
And for noble gas configuration or it can be called Condensed electron configurations :
[He]2s¹
The answer is B
In the word “homo” it means same and since the question keeps repeating same it should be homogeneous.
Answer:
945 km
Explanation:
remember the formula using the triangle DST: just keep in your mind dst
D fr distance, s fr speed or velocity, t fr time
...........D..............
......S..........T.........
distance = velocity * time
= 210 * 4.5
= 945 km
