Question on special case reactions between metal and acid

AI Thread Summary
Copper reacts with hot, concentrated sulfuric acid to produce copper (II) sulfate, sulfur dioxide, and water due to the strong oxidizing properties of sulfuric acid. This reaction occurs because sulfuric acid can oxidize copper, facilitating the formation of copper (II) sulfate while releasing sulfur dioxide gas. Similarly, when copper reacts with hot, concentrated nitric acid, it forms copper (II) nitrate, nitrogen monoxide, and water, again due to the oxidizing nature of nitric acid. Other metals that can react with hot, concentrated acids to produce gases include those higher in the reactivity series, which can also yield gases other than hydrogen. Strong oxidizing agents commonly used in these reactions include nitric acid and concentrated sulfuric acid, with perchloric acid being a less common option. Understanding the reactivity of metals with acids is essential for grasping the principles of oxidation-reduction reactions in chemistry.

I am a GCSE student and I am wondering why copper metal reacts with hot, concentrated sulfuric acid to produce copper (II) sulfate, sulfur dioxide, and water. Copper also reacts with hot, concentrated nitric acid to form copper (II) nitrate, nitrogen monoxide and water. Why do these reactions work? What other metals react with hot and concentrated acids this way to produce gases(not hydrogen gas)? Any help would be appreciated. I am just a GCSE student so pardon me if I do not understand certain explanations. Thanks!

Oh I see. What acids are strong oxidizing agents though?
 
Of those commonly used nitric and to some extent concentrated sulfuric. Of those less often used - perchloric acid.
 
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!!
