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. Element symbols are cut into each atom sphere: a self-labelled teaching aid. Ask the class whether Nitric Acid contains a ring. It does not: 5 atoms and 4 bonds (3 single and 1 double) make up an open structure. Quick starter: ask students to count the engraved symbols (1 H + 1 N + 3 O) and check that they add up to 5 atoms and the formula HNO3. On the printed model, students can…
