Constants | Periodic Table Chemical energy is released or absorbed from reactions in various forms. The most easily measurable form of energy comes in the form of heat, or enthalpy. The enthalpy of a reaction can be calculated from the heats of formation of the substances involved in the reaction: Part B AHm = En,AH: (products)-E n,AH (reactants) For the reaction given in Part A. how much heat is absorbed when 3.50 mol of A reacts? where n represents the stoichiometric coefficients. Express your answer to three significant figures and include the appropriate units. • View Available Hint(s) Value Units Submit Previous Answers X Incorrect; Try Again; 29 attempts remaining
