Then, the values from the standard enthalpy of formation table are multiplied by their stoichiometric coefficients and added together to calculate the overall enthalpy change of the reaction. The sign before the standard enthalpy of formation formula indicates whether the reaction is exothermic (negative...

Standard Enthelpy of formation of Graphene I am curious as to what the Standard Enthalpy of formation of Graphene is. I've noticed several highly technical papers on this subject but I got lost in the abstruse math and terminology. I am interested in the Standard Enthapies o both single ...
Homework Statement This is not a problem, per se, because it is part of my Lab. We're calculating the standard enthalpy change of formation for solid Ammonium Chloride. To do this, we're using four separate rxns, and totaling their individual standard enthalpy change of formations. For two...
