CO2: Enthalpy of Sublimation, Reaction and Metabolism

In thermodynamics, the enthalpy of sublimation, or heat of sublimation, is the heat required to sublimate (change from solid to gas) one mole of a substance at a given combination of temperature and pressure, usually standard temperature and pressure (STP). It is equal to the cohesive energy of the solid. For elemental metals, it is also equal to the standard enthalpy of formation of the gaseous metal atoms. The heat of sublimation is usually expressed in kJ/mol, although the less … WebMar 1, 2024 · Enthalpy of formation ( ΔHf) is the enthalpy change for the formation of 1 mol of a compound from its component elements, such as the formation of carbon … WebQuelques ASTUCES pour équilibrer une équation de réaction : 👉 Commence par faire l'inventaire des atomes présents dans les réactifs et dans les produits de la réaction 👉 Si … informaticage
