5 Chemistry questions? Thx a lot? I really need help.
Volume of HCl solution 100.5 mL HCl
Volume of NaOH solution 100.0 mL NaOH
Initial temperature in calorimeter 25.2 °C
Final temperature in calorimeter 28.2 °C

1. Write out a balanced equation for the reaction you investigated in Part II, including phase symbols.
2. Determine the enthalpy change of this reaction. The mass of the sodium hydroxide and the mass of the hydrochloric acid should be added together.
3. Determine the number of moles of NaOH.
4. Determine enthalpy per mole of NaOH. Show all of your work.
5. The value determi

anonymous · Answer

HCl (aq) + NaOH (aq)  ---> NaCl (aq) + H2O (l)
delta H = ms(Tf-Ti) for number 2, where delta H = enthalpy change, m = mass, s = specific heat, Tf = temperature final, Ti = temperature initial.
i believe you were given concentration of the acid/base? with that you can easily find moles by plugging into the Molarity formula
