Various types of nitric acid have been used in rocket fuels as oxidisers (RFNA is red fuming nitric acid, WFNA is white fuming nitric acid) as they are often hypergolic with a wide variety of fuels. …

Here, the compound itself appears to be non-aromatic, but if the double bond between the ring and the oxygen is broken into a single bond, with oxygen pulling the electrons towards itself and …

When introducing the concept of equilibrium constant, we often teach that the size of $K$ relative to $1$ indicates whether equilibrium lies toward the left (reactants) or right) products) of the …

(Partially answered by Safe silver electroplating solutions) Why is silver cyanide used as an electrolyte in silver plating? (source) There are other (cheaper, less toxic) silver salts, such as silver …

Long ago, I learned that suffixes like -ide, -ate, -ose, etc. had specific meanings. Now, I’m seeing all these drug ads on TV with generic names that all end in -ab or -ib. Do these have a standard …

Why is the depletion of the ozone layer greater in the winter months over polar regions? Is it because there is more release of NOx due to the increased use of fossil fuels in heating which depletes …

Forgive me if this is not the correct place to ask this. When I encounter a molar entropy, is it possible to rearrange the Boltzmann entropy formula $$S=k\log W$$ and meaningfully interpret the number …

We were told to rinse the buret with the base so that the concentration won’t be messed up, but when it comes to the flask that is going to hold the acid, there is no need to rinse, because it would …

What is the difference between thermodynamic and kinetic stability? I’d like a basic explanation, but not too simple. For example, methane does not burn until lit — why?
|

I’ve always been puzzled by this because my teachers happen to use only the KLMN method, but what is the difference between the KLMN and SPDF methods of finding electronic configuration?
|
|
What part in the strand contributes to the overall non neutral charge? DNA is not isolated in the body, so what keeps it stable while being charged? Why is it important for DNA to be charged?

When dealing with organic reactions, heating under reflux is often required, such as the oxidation of Toluene using acidified $\ce{KMnO4}$ and dilute $\ce{H2SO4}$ to Benzoic acid($\ce{C6H6O2})$ What …

Halogens bonded to benzene ring has three lone pairs. These three electron pairs can cause resonance in benzene ring. But, halogens are also highly electronegative and thus they have strong -I effect. …

In the crystal field theory (CFT), when the splitting of the d-orbital occurs, it gets divided into two parts. The upper part with higher energy is the $\mathrm{e_g}$ and the lower part with lower …

I’m reviewing some Physical Chemistry concepts and the two books I’m using show the total differential and right away they present the Schwartz’s theorem. I don’t get the relationship. In the …
