AI Thread Summary

When Cu(II)SO4 is mixed with sodium carbonate, a double replacement reaction occurs, resulting in the formation of copper(II) carbonate (CuCO3) and sodium sulfate (Na2SO4). In the second scenario, when Cu(II)SO4 is reacted with both sodium carbonate and sodium bicarbonate (sodium hydrogen carbonate), the reaction produces copper(II) carbonate hydroxide (CuCO3·Cu(OH)2) along with sodium sulfate. The difference in products between the two reactions is attributed to the presence of sodium bicarbonate, which introduces additional hydroxide ions that lead to the formation of the hydroxide component in the second product.

1.What will be produced when Cu(II)SO4 is mixed with sodium carbonate

2.What will be produced when Cu(II)SO4 is reacted with sodium carbonate and sodium hygrogencarbonate? What causes the difference between 1 &2?

Is the product for Qn2 CuCO3.Cu(OH)2aq?

Number one is a double replacement reaction, there should be an example of one in your textbook. In regards to number 2 I am not posative but i can check.

Thread 'Enthalpy - published values'

Do the published values of Enthalpy include the work done against a constant pressure, e.g., the atmosphere? (I am not a chemist). I am reviewing enthalpy and entropy as part of the statistical mechanics applied to transistors. I assume, from my reading, that the work done would mostly apply to reactions involving gasses.

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!!

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...
