The Attempt at a Solution


I tried using a enthalpy-concentration diagram, but I cannot read it. I would apreciate if anyone could help me!
 
Physics news on Phys.org
what is this diagram you have? what data are you provided with?
 
This one: http://docs.google.com/gview?a=v&q=cache:sexRAoFSlI4J:www.norfalco.com/documents/NorFalco_H2SO4Property07.pdf+calculate+enthalpy+sulfuric+acid&hl=en&gl=br

The only data I got is the concentration of the solution H2SO4 and water. I needed to find the theoretical enthalpy of solution for this reaction, to compare with the results I got from the experiment.

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
