Today, Our teacher had taught us that Cis-Trans Annulene(10) (i’m not sure if it is the correct nomenclature so I attatched the structure below) is non-aromatic. The reason he gave is due to …

I’m trying to figure out why $C$ is a matrix and not a vector in the Roothaan Equations. Below, I have a derivation which I have taken from this PDF in which, to me, $C$ appears to be a vector. But …

I have a doubt about the correlation between eutectic plots and freezing point lowering. The freezing point lowering, as well as all colligative properties, is defined in the presence of a volatile …

Are there natural enzymes that catalyze different reactions under different conditions? For example an enzyme undergoes a conformational change under certain pH and starts catalysing a different …

When preparing a copper etching plate for etching, it must be degreased completely before putting on the etching ground. Otherwise the acid may “bite” through the ground (“foul biting&…

How do I type a simple chemical equation in Microsoft Word? I can do subscripts, but long arrows are more difficult. I can’t get them to align with the text. Also, I can’t figure out how to put a …

I know that the lower the pH the faster fermentation occurs. Why does this happen?

Was looking at Henry’s law and Raoult’s law constants and there seemto be lots of equations involved. Henry’s law involves partial pressure and the latter involves the vapor pressure. Wondering what …

This is a 10th-grade question. The melting point of a substance decreases with increase in presence of impurities in it. The melting point of ice decreases from 0 °C to -22 °C on mixing salt in it …

Since fluorine has its valence electrons in the n=2 energy level, and since chlorine has its valence electrons in the n=3 energy level, one would initially expect that an electron rushing towards …

Wikipedia states that waxes can be dissolved by non-polar organic solvents. I failed to dissolve candle wax in both acetone and ethanol, which are the only organic solvents I have at home. I have …

I always have trouble naming my graphs in class. They never seem too scientific or professional. For example, we are reviewing density now, and had to graph the mass (Y) of different volumes (X) of …

Can you answer these questions?

I do not really understand the intuition behind the functions assigned to irreducible representations. For example, in H₂O, the A₂ representation is given by …

According to my textbook, Increasing the concentration of the reactants increases the rate of forward reaction only to reestablish equilibrium (Le Chatelier’s principle) But doesn’t that also …

I am planning to use coconut as a raw material for carbonization, but I need to crush it into 500 mesh coal. Currently, I am using a mortar and pestle to grind the coconut shell into a fine powder, …
