Iron(II) oxide vs iron(III) oxide in a thermite reaction

AI Thread Summary
The discussion centers on the differences between using Fe2O3 (iron(III) oxide) and FeO (iron(II) oxide) in thermite reactions aimed at producing aluminum oxide. A key point raised is that FeO may yield more energy due to its lower enthalpy of formation compared to Fe2O3. Additionally, the Ellingham diagram is suggested as a useful resource for understanding the thermodynamic properties and stability of these oxides in relation to aluminum reduction.

hey guys
i am wondering what the difference between using Fe2O3 or FeO would be in a thermite reaction to produce aluminium oxide.
wouldn't the FeO produce a more energy since its enthalpy of formation is lower?

thanks for your answers!

I am not sure about this but did you check out the ellingham diagram? This might give you the answer.
 
alright, thanks.
 

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!!
