AI Thread Summary
In a closed environment with hydrogen (H2) on one side and oxygen (O2) on the other, removing the partition allows the gases to mix. However, for a reaction to occur and form water (H2O), activation energy is necessary. This energy can be provided by a spark or other catalysts to initiate the reaction. The discussion highlights the importance of activation energy in chemical reactions, particularly in the formation of water from hydrogen and oxygen.

i studied chemistry about 6 years ago and don't remember much :smile:

I have a question though, let's say that you have a room and you put a partition in the middle of it. On one side is H2 and on the other is O2. Now if you remove this partition, do the H2 and O2 particles start to react with each other to form water or do you have to have some sort of catalyst to start this reaction (like a spark)?

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!!
