The discussion centers on the electrochemical reduction of ores and the refinement processes of various metals. Participants express uncertainty about which metals among a specified group are refined through electrolysis. It is noted that only two out of five metals in the question are typically electro-refined. Speculation arises regarding nickel and copper as potential candidates for electro-refinement, with participants indicating a need for further research to confirm their guesses. The conversation highlights the importance of understanding the methods used for metal refinement in the context of electrochemistry.

I know the clue in the question is that the ore is reduced by electrochemistry. However, which one is the right one? I don't know how the different metals in the question are refined. Can someone explain this to me? thanks.
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!!
