Question

match phase label to the element
barium choose
bromine choose
(l)
(s)
(g)
(aq)
iodine choose
nitrogen chcose
sulfur choose

Explanation:

To solve this, we recall the standard states (phases) of these elements at room temperature:

• Barium (Ba): Solid metal, so phase is (s).
• Bromine (Br₂): Liquid halogen, so phase is (l).
• Iodine (I₂): Solid halogen (crystalline), so phase is (s).
• Nitrogen (N₂): Gaseous diatomic molecule, so phase is (g).
• Sulfur (S): Solid (e.g., in its elemental form like S₈), so phase is (s).

Answer:

• barium: (s)
• bromine: (l)
• iodine: (s)
• nitrogen: (g)
• sulfur: (s)
