Published by admin at October 11, 2023 The enthalpy changes, ΔH , for three reactions are given. H 2 (g)+12 O 2 (g)Ca(s)+2H + (aq)CaO(s)+2H + (aq) ⟶H 2 O(l)⟶Ca 2+ (aq)+H 2 (g)⟶Ca 2+ (aq)+H 2 O(l) ΔH=−286 kJ/molΔH=−544 kJ/molΔH=−193 kJ/mol Using Hess’s law, calculate the heat of formation for CaO(s) using the reaction shown. Ca(s)+12 O 2 (g)⟶CaO(s) […]
