<p>Enthalpy of neutralization.</p> <p>Using 20.0 mL each of 1.0M HCl and 1.0 M NaOH to perform this reaction. Compute the enthalpy change (J/mole) for the reaction of acid (or base) neutralized. Assume that both the HCl and NaOH solutions have a density of 1.0 g/mL and that the specific heat of the salt solution formed is 4.18 J/gâÂºC. When the solutions are mixed, the temperature of the mixture increases from 23.9<sup>o</sup>C to 28.7<sup>o</sup>C.</p>
