Help me out because I attempted these and realized I did not solve them in Kj/Moles. How do you figure out change of enthalpy with the units kJ/moles?
My two reactions.
First balanced:
MgO (s) + 2 HCl (aq) --> MgCl2 (aq) + H2O (l)
Second balanced:
Mg (s) + 2 HCl (aq) --> MgCl2 (aq) + H2 (l)
Anyways, I got 8.39 KJ for the first, which I know isn't correct.
Could ya'll help me so that it would have correct units? Thank you, appreciate the help.
Do you want to calculate dHo for EACH reaction or do you want to calculate dHo for a third reaction in which these two reactions are used.
If the latter there is no third reaction given.
If the former you need the find the dHo std values in a table but I don't have tables that solutions without having concentrations also.
Perhaps if you will who the calculations in which you obtained the 9.39 kJ value I will understand where you're going with this. Thanks.
