Presentation Transcript

  1. Construct a Born-Haber cycle • Slides 2 and 3 show examples of the cards in use • Print slides 4 to 15 onto A4 paper or card • Laminate if desired, then cut into strips (use paper trimmer), and squares • Slides 4 to 9 will make 8 sets of cards for NaCl • Slides 10 to 15 will extend the 8 sets to also construct MgCl2 and MgO • Easily stored in envelopes for future use
