Consider the following reaction, which can take place in particle accelerators: 1 1H 1 1 0n h 2 1 1H 1 1 0n 1 1 21H Calculate the energy change for this reaction. Is energy released or absorbed? What is a possible source for this energy?
Chem 131 (10/24/16-11/4/16) Intro: here are the notes I’ve taken during Prof. Ondov’s lecture and from the textbook Chemistry: Structure and Properties 6th e ition by Nivaldo J. Tro Chapter 8: Chemical Reactions 8.1 chemical change- original substance transforms and matter of composition changes (eg. iron rusting, sugar burning, photosynthesis) ➢ Chemical Properties: corrosiveness, flammability, toxicity, acidity, etc. ➢ Usually indicated by temperature or color change physical change- original substance alters state of matter, not composition (eg. ice melting) ➢ Physical Properties: odor, taste, color, appearance, melting point, boiling point, etc. ➢ Usually indicated by change in state of matter or physical condition of matter 8.2 Chemical Equations stoichi
