Question

Which one of the following represents an element in its standard state at 25°C and 1 atm? A) Fe(l) B)Br2 (l)

Answer 1

The only two elements that are in a liquid (l) state at standard conditions are bromine (`Br`) and mercury (`Hg`)

Bromine as element is allways paired `Br_2`

Iron (`Fe`), as you know, is a solid at `25^0C`, so it should have been designated `Fe(s)`.
