Generally enthalpy values are given in kJ/mol. However, convert the enthalpy of neutralization value of -110.83 kJ/molNaOH to BTU/gram NaOH. BTU stands for British thermal unit. (Put your answer in 3 significant figures) Given the following information below, use Hess’s Law to calculate the enthalpy of formation for sodium oxide: Na (s) + HCl (l) à NaCl (aq) + ½ H2 (g) ∆HRx = -397.9 kJ/mol Na2O (s) + 2 HCl (l) à 2 NaCl (aq) + H2O ∆HRx = -652.8 kJ/mol H2 (g) + ½ O2 (g) à ...

Dashboard In organic chemistry, a common reaction is to reduce alcohols to form alkenes. Consider the following reaction: C H OH (1) + HCl(g) → C2H4 (8) + H2O (1) + HCl(aq) Here liquid ethanol is reacted with gaseous HCl to form ethene, water, and HCl dissolved in the water. Use the table below to determine at what temperature the reaction is spontaneous. Substance AH.° (kJ/mol) AGF (kJ/mol AS °...
