What is the molar heat of combustion for ethanol?

AI Thread Summary
To determine the molar heat of combustion of ethanol from the given data, first calculate the number of moles in 2.9 grams of ethanol using its molar mass, which is 46 g/mol. This results in approximately 0.063 moles of ethanol (2.9 g divided by 46 g/mol). Given that burning 2.9 g of ethanol releases 87 kJ of heat, the next step is to find the heat released per mole. To do this, divide the total heat released (87 kJ) by the number of moles (0.063). This calculation yields a molar heat of combustion of approximately 1381.0 kJ/mol for ethanol.

The question i am stuck on is "If 2.9g of ethanol burn with the evolution of 87 kj of heat, what is the molar heat of combustion of ethanol?" thank you for your help if it possible you can tell me how to do this question.

2.9g ethanol - how many moles?
 
so basically so find how many moles of ethanol in 2.9g

So u do, 2.9g/46 (46 being the molar mass of ethanol)
 
87 kJ for 2.9/46 moles, how much for 1 mole?
 

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...

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!!
