Hi, i have a lab question and i'm kind of confused on how to approach it.

evaluation of molar enthalpy of dissociation of formic acid, deltahdiss.

given:
h1 = -58010 j/mol; h2 = -59758.4j/mol

they tell use to use hess's law to determine the enthalpy of dissociation

!

Hess' Law uses manipulation of the equations used to form the correct equation in total.
 
 1. H3O+ + OH- > 2H2O                             H1= -58010 J/mol
 2. HCOOH + OH- > H2O + HCOO-          H2 = -59758 J/mol
 
2. HCOOH + OH- > H2O + HCOO-           H2 = -59758 J/mol
1. [x-1] = 2H2O > OH + H3O                       H1 = 580101 J/mol

HCOOH + H2O > H3O + HCOO                     H= -1748 J/mol

Iwould google this

The answer would be
