HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (l) The reaction liberates heat to form H2O in the liquid state. Hence, it is an exothermic reaction. Enthalpy associated with any reaction is called reaction enthalpy. Thus, the enthalpy of neutralisation is the heat liberated when acids react...
I also struggled to find the moles. What moles do I find? the NaOH or HCl? I wasn't sure, but I just used the HCl. n(HCl)=0.025L x 0.5M =0.0125mol ΔH=-0.6935kJ/0.0125mol =-55.48kJ/mol Could you help me understand how to find the mass and which moles to use? Thank you...
