2Cu+6HNO_3\xrightarrow~2Cu(NO_3)_2+3H_2O+2NO_2

2Cu(NO_3)_2~+~2Na_2CO_3~+~H_2O\xrightarrow~CuCO_3~\cdot~Cu(OH)_2~+~4NaNO_3~+~CO_2

2HNO_3+Na_2CO_3\xrightarrow~2NaNO_3+CO_2+H_2O

CuCO_3~\cdot~Cu(OH)_2\xrightarrow{\Delta}~2CuO+H_2O+CO_2

CuO+H_2SO_4\xrightarrow~CuSO_4+H_2O

CuSO_4+Mg\xrightarrow~MgSO_4+Cu

H_2SO_4+Mg\xrightarrow~MgSO_4+H_2

They look okay.

Daniel.
Thank you.
 
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!!
