gold - 2024 ACF Winter - Buzzpoints App

Question

A lab at Rice University discovered that “seeds” of this element used to synthesize nanoparticles are structurally equivalent to 32-atom buckyball-type clusters. For 10 points each:

[10e] Chemotherapy makes widespread use of nanoparticles of what non-platinum metal dissolved by aqua regia?

ANSWER: gold [or Au]

[10h] This is the first procedure proposed to synthesize colloidal gold nanoparticles. The treatment of chloroauric acid with sodium citrate in this procedure forms gold nanowires before the solution turns ruby-red.

ANSWER: Turkevich method [or Turkevich–Frens method]

[10m] Gold nanoparticles coated with a polymer of this compound have many applications in cancer treatment. Most antifreeze agents are based on this two-carbon compound with two terminal hydroxyl groups.

ANSWER: ethylene glycol [or ethane-1,2-diol; accept polyethylene glycol or PEG]
