2 The halogens, chlorine, bromine and iodine, and their compounds, show a variety of similarities and trends in their physical and chemical properties.(a)(i) Give the colours and states of chlorine, bromine and iodine at room temperature and pressure.halogen colour state chlorine bromine iodine...
the atomic number of bromine is 35. Its atomic mass is 79.904. Bromine stays as a red-brown colour liquid at room temperature. It exists as a diatomic molecule, Br2. Moreover, it is toxic

element, mercury is the only metallic element that is known to be liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature...
When phenol reacts with concentrated sulphuric acid,Phenol reacts with sulfuric acid giving substituted phenols. At room temperature an equilibrium is established between a mixture of phenol sulphuric acid and the product benzene ortho hydroxy sulfuric acid. ...
At room temperature, hydrogen bromide is a colourless gas, like all the hydrogen halides apart from hydrogen fluoride, since hydrogen cannot form strong hydrogen bonds to the large and only mildly electronegative bromine atom; however, weak hydrogen bonding is present in solid crystalline hydrogen br...

Benzenamine (Aniline) reacts with bromine water at room temperatureto give a white precipitate of 2,4,6-tribromoaniline. Is BR a bromine? Bromineis a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temp...
The atomic weight of bromine is 79.904 amu. Under room temperature, it exists as a diatomic molecule (Br2). Also, this diatomic molecule is a Red-brown colour liquid. Bromine has a melting point of 265.8 K and a boiling point of 332.0 K. ...
It is the third-lightest halogen and is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and ...
