What is theΔH(enthalpy change) for the reaction 2NH3→N2+3H2 ΔfH∘(NH3)=−46.0kJ/mol. Enthalpy Change of Reaction: The enthalpy change of the reaction is a value that can be estimated with the help of the enthalpy of formation ...
Why does the enthalpy of formation for the ethanol dimer have more energy than two isolated ethanol molecules? How many parts per million is the lower explosion limit for ethanol? Why would ethanol be used to wash a precipitate after that precipitate had been washed with water?
