Symmetry and angular momentum in the Jahn-Teller paper
We first consider a linear molecule with $C_{\infty \mathrm{v}}$ or $
D_{\infty \mathrm{h}}$ symmetry, but we will work with only the $C_{\infty }$
subgroup, representing rotations around the ...

Where does Conjugate base [A-] concentration come from in HA dissocation that is used in derivation of kb*ka=kw?
Reactions
\begin{align}
\ce{HA +H2O &<=> A- + H3O+} &K_\text{a}=\dfrac{[\ce{H3O+}][\ce{A-}]}{[\ce{HA}]}\tag{1}\\
\ce{A- + H2O &<=> HA + OH-} &K_\text{b}=\frac{K_\text{w}}{...

Why is Ammonia a strong base?
Ammonia (NH₃) is a weak base, not a strong base. Here's the simple reason:
Ammonia has a lone pair of electrons on nitrogen, which lets it grab a proton (H⁺) from water. This makes hydroxide ions (OH⁻)...

Bond length comparison between sulfur tetrafluoride and thionyl tetrafluoride
Basic knowledge:
All orbitals of SF4 and SOF4 that are in their respective triangular planes are SP^2 hybridized.
Let us first disregard the axial bonds as they are not asked in the question and don't ...

Is hydroxylamine monodentate or ambidentate ligand?
from an exam perspective:
when geometric isomers are asked, you cannot consider two different linkages.
even if it were ambidentate, you must assume a consistent linkage among the geometrical isomers ...

Is there a way to classify chemicals as GHG positive/negative based to whether they have a higher tendency to react with a GHG or be a side product?
If I understand your question correctly, you have a given list of compounds, and you want to know if they can be considered "good" or "bad" in the sense that they either contribute ...

What is the structure of scandium hydroxide?
The German Wikipedia page gives a structure for $\ce{Sc(OH)3}$ in which each scandium atom is octahedrally coordinated to six hydroxyl groups*. With 3:1 stoichiometry this would suggest a perovskite ...

Can I process pyroxene or olivine as a part of magnesium thermite?
Yes, you actually somewhat can
TLDR: go to the bottom.

Why is dinitrogen tetroxide a planar molecule?
Both the σ-bond at $\ce{N – N}$ and the length of this bond do allow for a lot of room to move around. On the surface, one would think it would be prone to a non-planar structure, especially as the ...

N-N bond length in Dinitrogen Tetroxide
I think I can suggest an intuitive argument as to why the molecule of N2O4 is planar despite the electrostatic repulsion between the oxygen atoms (which does not favour planarity). The reason is ...

What makes Metal Organic Frameworks (MOF) interesting in the field of catalysis (electro or Photocatalysis)? why so much recent exploration of MOF?
Being able to tailor the open pore size (and its distribution) allows you to be selective about the (maximal) size of molecules/branch of molecules able to enter the cavity of these heterogenic ...
