  2. Iodine is dar grey at room temperature and has a purple vapour when heated; Bromine is a dark red liquid at room temperature which gives a red-brown vapour.

    1. Bitch please why don't you just tell her what she's doing wrong instead of insulting her.

      Thank you.

    2. there's no point insulting her. she's doing amazing work and helping loads of people, so if you want to make pointless, rude comments, go start your own blog and see how that turns out.

      Hint: not as good as this.

      Hannah’s done an amazing job and has helped so many people - posting immature comments doesn’t do any good for anyone.
