Methane, ammonia, and carbon dioxide are all familiar compounds that are in the gas phase at normal temperatures.
true lighting can turn nitrogen compounds into gas
Neon is a noble gas, which does not form any compounds.
Xenon ( At no 54 ) forms the maximum number of compounds for an noble gas
No it is a mixture of compounds.
Many.
At normal temperature ionic compounds are neither liquid nor gas they are always solid compounds.
No. Gas is a state of matter. Gasses can be elements, compounds, or mixtures.
sulfur
There are no common compounds of helium and probably are no compounds of helium at all, because helium is the least reactive of all elements.
Those compounds produce hydrogen (gas).
No, noble gas compounds can only be produced artificially.
"Sweet gas" in petrochemistry is defined as a (natural) gas low in concentration of sulphur compounds (in particular H2S)
