  • This is a brown gas and is poisonous. It causes acid rain (8, 7)
  • This is the gas in gas taps, it burns with a blue flame (7)
  • This is the gas we breathe, it puts flames out and turns limewater a milky colour (6, 7)
  • This is the gas we need to stay alive, it relights a burning splint, and it is needed for burning (6)
  • This makes up 78% of the air, a glowing splint will go out and the gas is very unreactive (8)
  • Used in lightbulbs and doesn't react at all (5)
