Question

Initial temp: 19.06 C

0.5 M concentration 200 mL of HCl and 200 mL of NaOH are combined in an insulated container.

H+(aq) + OH-(aq) - - -> H2O (l)

∆H H++ = 0, ∆H OH−− = -230 kJ/mol, ∆H H2O = -286 kJ/mol

∆H reactants = ∆H H++ + ∆H OH−−

= -230 + 0

= -230 kJ/mol

∆H reactants = -286 kJ/mol - ( -230 kJ/mol)

= -56 kJ/mol

H+ (aq) + OH− (aq) - - -> H2O (l)
Using your observations and the stoichiometric relationships of the reaction, determine the number of moles that react. Show/upload your work.
