Answer:
3.75 L
Explanation:
We can solve this problem by using <em>Charles' law</em>, which states:
Where subscript 1 stands for initial volume and temperature and subscript 2 for final volume and temperature, meaning that in this case:
We <u>input the data</u>:
- 2.5 L * 300 K = V₂ * 200 K
And <u>solve for V₂</u>:
The mass would be the sum of the protons and neutrons. Your answer would be 218
It must absorb energy in the form of for example heat which gives it the energy required to become excited
hope that helps
Potassium has one electron in the 4 s sublevel and can easily lose this electron, so it has a low first ionization energy.
Therefore, it lose the 4 s electron to achieve an Argon electron configuration, giving it the added stability of the filled p sublevel.
The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).
Potassium has lowe first ionization energy, so potassium easier remove one valence electron (4s¹).
Electron configuration of potassium is: ₁₉K 1s²2s²2p⁶3s²3p⁶4s¹.
Electron configuration of argon atom: ₁₈Ar 1s² 2s² 2p⁶ 3s² 3p⁶.
Hey there!
There are 6.022 x 10²³ atoms in one mole.
We have 5.33 x 10⁻⁵ moles.
(5.33 x 10⁻⁵) x (6.022 x 10²³)
3.21 x 10¹⁹
There are 3.21 x 10¹⁹ atoms in 5.33 x 10⁻⁵ mol C.
Hope this helps!
