Which of the following statements are incorrect? Select all wrong statements: A) based on the terms and symbols used in the discussions on thermochemistr, the expression, delta E = delta H - PdeltaV is incorrect. B) the concept of an average kinetic energy suggests that there is a range of different kinetic energies among the particles of a substance. C) as heat is transferred to ice cubes, its water molecules gain kinetic energy, causing the ice to melt. D) the following thermochemical equation indicates that 184.8 kJ are released, if two moles of hydogen react with nitrogen to form ammonia, Na(g) + 3 H2(g) —> 2NH3( g), deltaHdegree = -92.38 kJ.
