Witryna17 wrz 2016 · The reaction with sodium is a redox reaction (note the changing oxidation state of hydrogen from +1 to 0), whereas that with NaOH is merely acid-base. As for the reaction with NaOH, it will certainly proceed, but in general will probably not go to completion (see also vapid's comment on the answer). – orthocresol Sep 17, 2016 at … Witryna27 paź 2024 · The enthalpy change when 1 mole of HCl reacts is −58 kJ. Since that is the number of moles in the chemical equation, we write the thermochemical equation as: HCl ( aq) + NaOH ( aq) NaCl ( aq) + H 2O ( l) ΔH = − 58 kJ Exercise 5.3.1 When 1.34 g Zn (s) reacts with 60.0 mL of 0.750 M HCl (aq), 3.14 kJ of heat are produced.

WitrynaSo when NaOH reacts with H2O, the enthalpy of the solution is -40 kJ ± 7 kJ. Since the enthalpy value is negative, it means that energy is lost, probably due to heat to the surrounding, which in this case was the water. Since it gives away energy, it is an exothermic reaction. The value of -40 kJ ± 7 kJ can be supported by the literary values. WitrynaColumn 3 is the calculation formula for each answer, where mw and ms are the mass of the water only and the mass of the total solution, respectively, and n* and m* are the moles of NaOH and the mass of NaOH, respectively. Column 4 is the test response percentage of each answer choice.
Witryna10 lut 2010 · Assuming liquids (25% NaOH and H2O) of 77 0F initial temperature, enthalpy of 25% NaOH solution is (say) 32 Btu/lb and enthalpy of 20% NaOH is (say) 31 Btu/lb (scale does not permit to distinguish these figures well), according to Perry's Fig 2-29 (enthalpy concentration diagram for aqueous NaOH solution).
