Nitric Acid 3D Molecular Model — CAS 7697-37-2

Nitric Acid (HNO3, CAS 7697-37-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. Symbols are engraved into every atom, so students read atoms by symbol, not by colour. Follow the chain of Nitric Acid from end to end: 5 atoms, 4 bonds (3 single and 1 double) and no ring anywhere. Give each pair of students the model and a blank sheet: recording every engraved symbol should lead them to 1 H + 1 N + 3 O, which is 5 atoms. On the printed model, students can point…
