High school Chem and reactions?

AI Thread Summary
In high school chemistry, balancing chemical reactions and predicting products are fundamental skills. The concept of octets, while useful, primarily applies to second-period elements and does not universally determine reaction feasibility. To assess whether certain reactions are possible, one can explore the field of Reaction Prediction, which provides guidelines and methods for evaluating chemical interactions. Resources like YouTube offer instructional videos on this topic, enhancing understanding of reaction possibilities. Overall, not all reactions can occur simply based on valence electrons achieving an octet.

In high school chemistry, which I am in right now, we are the very simple means by which to balance a chemical reaction and determine the products of a reactions. My question is; is any reaction possible as long as the valence electrons of the reactants equal eight? Obviously the answer is no, but how would you determine if certain reactions are possible or not.

Octets work reasonably well only for 2nd period.
 
There is a whole part of Chemistry called Reaction Prediction. You can look it up on YouTube to see instructors explaining how to predict the reaction that would occur between different chemicals.
 
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!!
