Bond Enthalpies Principles to Production: Chemical Energy.
Do now! Can you stick the slides in your book please (cut round the edges, but don’t cut out each individual slide – it takes too long!).
Energy Changes You will learn about: Exothermic & Endothermic Reactions Energy level diagrams Bond Making and Breaking Calculating enthalpy change.
Can you guess the topic for today?
Bond…. Bond Energy. All physical stuff is made of … –Matter! (Chemicals – atoms and molecules) In Chemical reactions, atoms rearrange to form new substances.
