AI Thread Summary

The discussion centers on whether a catalyzer in a chemical reaction can also serve as an intermediary. There is uncertainty about this possibility, with the argument that a true catalyst should not be consumed in the reaction. However, it is noted that certain biological processes, such as the Krebs Cycle, feature intermediates that can also act as catalysts for earlier stages of the reaction. The mention of bromine (Br) raises questions about its role in this context, suggesting that some substances might fulfill both functions in specific scenarios.

Can a catalyzer in a reaction be an intermediary as well?

Im not sure, i don't think because it would have to consume it self...

It is possible. In fact, I believe the Krebs Cycle has intermediates that also catalyze an earlier stage in the reaction.

Would Br be an example?

Thread 'Enthalpy - published values'

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.

Thread 'Why does having 8 valence electrons make an element inert?'

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!!

Thread 'Solubility of MgSO47H2O in water'

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...
