It does not support the combustion of a taper, but burning phosphorus and red-hot carbon will continue to burn in the gas.
The metals of the alkalis and alkaline earths, also magnesium, burn in sulphur vapour as they do in oxygen.
It does not burn, and does not support ordinary combustion, but the alkali metals and magnesium, if strongly heated, will continue to burn in the gas with formation of oxides and liberation of carbon.
Io, the gas and air in one phase enter at the bottom of all three of the large vertical chambers, burn in passing up wards, and escape at once at the top, as shown by the broken m arrows.
The element combines directly with the halogens, sulphur and selenium, and most of the metals burn in its vapour forming phosphides.
