Chem Help?

[FirebirdFlying]

Anyone happen to know the accepted change in enthalpy values for a) aqueous NaOH + aqueous HCl, b) the dissolution of solid NaOH, and c) solid NaOH + aqueous HCl? I lost my notes, need to calculate experimental error, and finding anyone in the class with ready access to theirs is proving rather difficult. I'm going to try to find the teacher at conference, but just in case, I'm asking y'all.

Thanks!

(I know, I know, I can probably calculate it with the heats of formation and whatnot. However, I don't particularly want to mess it up. Which I might.)

Ok so the Delta H values I got from the back of my book are thus: NaOH (s): -425.6 NaOH (aq): -469.2 HCl (aq) -167.2 NaCl (aq) -407.3 H2O (l): -285.8. All those figures are in KJ/Mol, using Products - Reactants you should be able to calculate all the data you need. I'm just to lazy to do it for you.:smalltongue:
