@SafdarFaisal I'm gonna occassionaly ping you, I hope you don't mind :') This is another answer with 25k views that could use some fresh replies. Thanks!
Although this is a particularly hard question, iirc, serious chemists don't use this concept of covalency anymore (?). So the whole concept of covalency in itself is just kinda ill-defined, which makes it difficult to give usable answers using it :/ (at least I think so)
I have recently found out that the white/yellowish "sweat" stains one occasionally finds on t-shirts might be aluminium chlorohydrate polymers.
While talk about aluminium and antiperspirants is all over the press and there are lots of DYI-instructions for removing them, they all sound quite pse...
Question
An aqueous $\ce{KNO3}$ solution has a molality of $\pu{4.16 m}$ and a density of $\pu{1.08 g/mL}$. Calculate the percentage by mass $\ce{KNO3}$ of the solution.
My Approach
I know that molality ($b$) is defined as:
$$b = \frac{n_\mathrm{solute}}{m_\mathrm{solvent}}$$
In order to the m...
We were told in a first year introductory Thermodynamics and Kinetics lecture, and also from Wikipedia, that there are 3 main assumptions for the derivations used in Transition State Theory, but I'm not sure how or why they have been assumed?
Reactants are in constant equilibrium with the transi...
