DESCRIPTION
TRANSCRIPT
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
