Calculate the standard enthalpy change (∆H°) for the neutralization reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) given the following information:- Balanced chemical equation: HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)- ∆H°f of NaCl(aq) = -407.3 kJ/mol- ∆H°f of H2O(l) = -285.8 kJ/mol- Heat capacity of the system, Cp = 4.18 J/g.K- Mass of the HCl solution used = 50.0 g- Concentration of HCl solution = 0.100 M- Volume of NaOH solution used = 100.0 mL- Concentration of NaOH solution = 0.200 MAssume that the specific heat of the solution is equal to that of water at 4.18 J/g.K and that the density o

An unknown compound was analyzed using mass spectrometry, and the resulting spectrum showed a molecular ion peak at m/z 214. Fragmentation patterns were also observed with peaks at m/z 121 and m/z 93. Can you identify the unknown compound and explain the fragmentation pathways leading to the observed peaks?
