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.
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.
