The discussion centers on the absorption ratio of water humidity over time and the need for empirical evidence to support claims. Participants emphasize the importance of experimental measurement and suggest that individuals can conduct their own experiments to determine absorption rates. Additionally, it is noted that data tables from silica gel producers may provide documented properties and absorption information, serving as a valuable resource for those seeking proof of absorption ratios.

What is the absorption ratio of the water humidity of each in a given period of time, is there any proof?
As I said - you can do the experiment by yourself and check.
Pus, there should exist data tables, prepared by others, that contain this kind of information. I suppose silica gel producers have them and will be quite happy to document properties of things they sell.
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
Do the published values of Enthalpy include the work done against a constant pressure, e.g., the atmosphere? (I am not a chemist). I am reviewing enthalpy and entropy as part of the statistical mechanics applied to transistors. I assume, from my reading, that the work done would mostly apply to reactions involving gasses.
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert?
What is so special with a full p orbital?
Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive.
Can someone explain it to me?
Thanks!!
