Flammability code 1: Must be pre-heated before ignition can occur. Flash point over 93 °C (200 °F). E.g. canola oilHealth code 0: Exposure under fire conditions would offer no hazard beyond that of ordinary combustible material. E.g. sodium chlorideReactivity code 1: Normally stable, but can become unstable at elevated temperatures and pressures. E.g. calciumSpecial hazards (white): no code

Reactions

When vaporized Europium(III) bromide reacts by the equation:

  • 2 EuBr3 → 2 Eu + 3 Br2[3][7]

Europium(III) bromide is also created through the equations:

  • 4 EuBr2+ 4 HBr → 4 EuBr3 + 2 H2[7]
gollark: Ah, Discord is back.
gollark: You should resolve this.
gollark: I'm surprised we don't have Apioforum johnvertisements.
gollark: That would be a very weird law.
gollark: Why?
