Reversible reaction activated only by thermal energy

AI Thread Summary
The discussion centers on the search for a reversible chemical reaction that can be activated solely by thermal energy, allowing for the release of stored thermal energy upon returning to its initial state. A suggested example is the precipitation of sodium acetate from supercooled solutions, which can be easily demonstrated in a lab setting. This process, often referred to as "Hot Ice," serves as a practical illustration of thermal energy storage through phase change materials. The concept aligns with the idea of storing energy in a simpler manner than the complex synthesis of glucose in glycolysis.

Dear all,

I am not an expert of Chemistry and I would like to know if there is a reversible reaction that can be activated only by thermal energy. The result of the reaction should be something which can be brough again to the initial state, releasing again the thermal energy stored. I was thinking to something similar in concept to the glycolyse (in which the solar energy is stored in the molecule of glucose and this energy is released when the molecule is broken), but simpler to implement in lab. As I have understood, the synthesis of glucose is not simple and it does not require only thermal energy.

Please let me know.

Thanks a lot,
Stefano

The precipitation of sodium acetate from supercooled (achieved by heating) solutions does just that. Google "phase change materials thermal storage".
 

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!!
