Answer:
S>O.
Explanation:
Chemical changes can reduced entropy in an open system. When gas turns into a liquid or when a liquid turns into a solid; entropy is reduced. hope this helps you :)
Answer:
Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom. The electrons are filled according to Afbau's rule in order of increasing energies.
The last electron enters the third shell in all elements from Sodium to Argon.
Hemiacetals are compounds that are derived from aldehydes and ketones while acetals are compounds with a central carbon atom with 4 bonds attached to it. It must be saturated and has a tetrahedral geometry.
The number of molecules : N = 1.505 x 10²³
<h3>Further explanation</h3>
Given
0.25 mol N₂O₄
Required
The number of molecules
Solution
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
N = 0.25 x 6.02.10²³
N = 1.505 x 10²³
