Practical Endothermic reactions

AI Thread Summary
Spontaneous endothermic reactions are effectively utilized in instant cold packs for injury treatment, showcasing their practical applications. Other potential uses include drink packs that activate a cold reaction shortly before consumption, enhancing the cooling effect. The discussion also touches on protein synthesis, which is endothermic and essential for life. The evaporation of gas is mentioned as a potential endothermic process, particularly when using pressurized aerosol liquids to cool electronic components for temperature sensitivity testing. Additionally, endothermic reactions can temporarily numb skin for minor surgical procedures, although it is noted that this may not involve a chemical reaction but rather a change in kinetics affecting pain signal transmission.

I understand that spontaneous endothermic reactions are used rigorously in the design of instant cold packs to treat injures.

Can someone please list and suggest other uses of spontanous endothermic reactions that can be used practically in everyday life

I've seen it proposed for a drink pack where part of it was given over to an endothermic chem mix. You activated the reaction a few minutes before consuming the cold drink.
 
Protein synthesis is endothermic. You could literally not live without it.
 
Does the chill due to evaporation of gas qualify as endothermic here? If so, a pressurised aerosol liquid can be sprayed onto a problem circuit board chip or component to assess whether it is temperature sensitive.

Similar thing can be used to temporarily deaden an area of skin to allow minor surgical procedures, e.g., extracting a splinter, lancing a boil. http://img717.imageshack.us/img717/4080/3110y.gif

what reaction is taking place here?
 
None. I think you are just altering kinetics, slowing down all reactions - and changing how fast the nerves transmitting pain signal can work.
 

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...

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!!
