Wait until a while ring of solid ammonium chloride forms where the hydrogen chloride and ammonia gases meet. The ammonia gas, having a lower molecular weight than the hydrogen chloride, will diffuse ...

Gas transport through a metal cluster-containing crystalline solid. Hydrogen and carbon monoxide travel at different speeds due to their molecular size relative to the size of nanoscale tunnels in the ...

Researchers from Tokyo Metropolitan University have elucidated how hydrogen and carbon monoxide is adsorbed into solids ...
