Write the balanced molecular, total ionic and net ionic equation for the neutral

Question

Write the balanced molecular, total ionic and net ionic equation for the neutralization reaction between hydrochloric acid and sodium hydroxide. Using a reference source, find the heat of reaction for the neutralization reaction between hydrochloric acid and sodium hydroxide. Cite your source completely. A student followed the procedure in this experiment, using 50.00 mL of 1.00 M HCl and 51.00 mL of 1.00 M NaOH both solutions having an initial temperature of 25.5c. After mixing, a maximum temperature of 32.2 C is measured. For this problem, assume the density of the solution is 1.040 g/mL and its specific heat is 4.18 J/g C. Calculate the enthalpy change for the neutralization reaction. Calculate the experimental error compared to the accepted your value in question 2.
