Sulfuric Acid 3D Molecular Model — CAS 7664-93-9

Sulfuric Acid (H2O4S, CAS 7664-93-9) — a free educational 3D molecular model for teachers and students, by MolGod.org. No legend required: the element symbol is engraved on each atom. No ring closes anywhere in Sulfuric Acid, which makes it a good open-chain example: 7 atoms, 6 bonds, 4 single and 2 double. Use the engraved letters like a register: call out each element and tick it off until the class reaches 2 H + 4 O + 1 S (7 atoms altogether). Spot-the-group challenge: can students find the…
