AI Thread Summary
High temperatures can neutralize explosives by incinerating the dangerous chemicals rather than triggering a detonation. In the controlled burn of a condemned house, temperatures reached between 1,500 to 1,800 degrees Fahrenheit, which was sufficient to neutralize the explosives present. While some explosives can burn rather than explode, they typically require a specific trigger, such as a shock wave, to detonate. Although the fire did cause a few minor explosions, they occurred randomly rather than in a coordinated manner. The sensitivity of explosives varies significantly, with many high explosives designed to be less sensitive to friction, shock, and heat, making it difficult to generalize their behavior without knowing the specific types involved.

With respect to the http://www.kusi.com/story/13646760/bomb-factory-house-leveled-by-controlled-fire?redirected=true", why do high temperatures neutralize explosives instead of setting them off?

The controlled burn resulted in temperatures of 1,500 to 1,800 degrees inside the condemned house, enough heat enough to neutralize all the dangerous chemicals stashed and strewn throughout, said San Marcos Fire Chief Todd Newman, one of the supervisors of the operation.

Many explosives are can burn instead of explode - they need something that will start detonation. High temperature is not enough, as it doesn't create necessary shock wave.
 
The fire did set off some of the explosives--there were reports of a few pops. However, it looks like they didn't go off in any organized way. Also, Borek is correct: many "high explosive" compounds are employed for their lack of sensitivity. The sensititivity to friction, shock, and heat varies from compound to compound though, so it's hard to make generalizations as to why the house didn't explode without knowing what kinds of explosives were in there.
 
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...
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!!
