Witryna24 sie 2024 · According to the Intergovernmental Panel on Climate Change, methane traps heat and warms the planet 86 times more than carbon dioxide over a 20-year horizon. Other sources indicate that methane, although far less prevalent, is a greenhouse gas 30 times more potent than carbon dioxide. Witryna18 kwi 2024 · Methane ( C H X 4) is less dense than air, but not by nearly as much as H X 2 which is generated by reactions mentioned in other answers. I've never tried the reaction myself but I believe it is comparatively less vigorous than hydrogen generation from alkali metals or alkali earths.

WitrynaThat means the density of an ideal gas is proportional to its molecular weight, so hydrogen ( M w = 2) and helium ( M w = 4) are lighter than air (average M w = 28.8 ). However you're asking about liquid hydrogen and helium, and liquids are much denser than gases because the molecules are much more tightly packed. Witryna13 wrz 2011 · Methane's (CH4) formula mass is 12+ 4 or just 16 - so it is lighter than air as the formula mass (and hence density) is less than 28. Carbon Dioxide (CO2) has …
