When irradiated with light of wavelength 471.7 nm, the chlorine molecule dissociates into chlorine atoms. One Cl atom is formed in its ground electronic state while the other is in an excited state that is 10.5 kJ/mol above the ground state. What is the bond enthalpy of the Cl2 molecule?
General Chemistry 211 Chapter 1: Matter Info. 1. Chemistry involves the study of the composition, properties, and transformation of matter. 2. The fundamental properties of all matter include physical and chemical: a. Solid b. Liquid c. Gas Important stages of matter(transformation) d. Plasm i. Chemical involve the change of reaction 1. Ex: Iron ii. Physical involve the change of formation 1. Ex: Liquid 3. Change in the state or chemical composition of matter involves what two principal forms of energy is kinetic and potential: a. Energy i. Potential Energy=position (the field of force) 1. Mas
