AI Thread Summary
Diesel fuel can appear to glow bright green or yellow against a white background, especially in snowy conditions. This effect is due to the presence of fluorescent compounds in the diesel, which can emit light when exposed to bright light sources. The glowing appearance is not an illusion but a result of these compounds reflecting light. Additionally, if the diesel is observed in the dark, it may exhibit phosphorescence, allowing it to continue glowing after the light source is removed.

I had some diesel fuel outside and it was snowing pretty good and it looked like it was glowing bright green/yellow against the white background. Was it glowing or was it just an illusion?

It contains fluorescent compounds so in the bright light you would see it glow somewhat. Its phosphorescent if you continue to see it in the dark.
 

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!!
