i think it will be hydrogen mate coz when u put on the lpg stove it gives blue flames..........
Earth.
blue
Flatulent gas
sulphur S + O2 = SO2
In a flame test the copper ions in copper chloride will produce a 'blue/green' flame. To test for metal ions, the flame colour in a flame test is indicative of the metal present. Lithium = Red Sodium = Yellow Potassium = Lilac (pale purple). There are many more flame test colours.
Lithium flame gives a lilac colour when ignited.

sodium gives off an orange to yellow flame colour
blue
Flatulent gas
Some common metals I can think of are: Magnesium, Mg, which gives a bright white colour; Ca, which gives a brick red flame; K, which gives a purple flame; Na, which gives an orange flame etc...
Potassium
Its Flame Test:it gives golden yellow colour to non luminous flame which is not seen through a blue glass.
sulphur S + O2 = SO2
There is no chemical element that gives it its dark color, but rather minerals, which are compounds. Andesite's dark color is due to the presence of pyroxene and some hornblende.
This compound is potassium chloride.
