AI Thread Summary
The discussion focuses on a significant assignment in the Netherlands that is crucial for exam eligibility. The chosen topic is the development of an anti-graffiti agent, with a primary focus on chemistry and a minor in physics. The individual seeks guidance on how to begin the project, suggesting that researching the ingredients used in spray paint could be a useful starting point. There is a call for additional ideas and resources on how to effectively proceed with the assignment, particularly in relation to anti-graffiti solutions.

Here in the Netherlands I'm supposed to do a big assignment spanning over a couple of months. Without doing it, I won't be allowed to make my exams, so it's pretty important.

I chose to do it about Chemistry (with, as a minor subject, physics). As a subject I chose to work on an anti-grafitti agent (is that the right word?)

I wonder if anyone could give me hints on where to start. I suppose actually looking at the ingredients for spray paint is a nice start, but for the rest I don't really have ideas on how to proceed.

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!!
