Njengamanje, imakethe yomhlaba wonke ye-xenon ephezulu ...Funda kabanzi -
Yini i-silane?
I-Silane iyinhlanganisela ye-silicon ne-hydrogen, futhi iyitemu evamile yochungechunge lwezinhlanganisela. I-Silane ikakhulukazi ihlanganisa i-monosilane (SiH4), i-disilane (Si2H6) nezinye izinhlanganisela ze-silicon hydrogen ezisezingeni eliphezulu, ezinefomula evamile i-SinH2n+2. Kodwa-ke, ekukhiqizeni kwangempela, ngokuvamile sibhekisela kuma-monos...Funda kabanzi -
Igesi ejwayelekile: isisekelo sesayensi nezimboni
Emhlabeni omkhulu wocwaningo lwesayensi nokukhiqizwa kwezimboni, igesi evamile ifana neqhawe elithule ngemuva kwezigcawu, elidlala indima ebalulekile. Ayinayo nje inhlobonhlobo yezinhlelo zokusebenza, kodwa futhi ikhombisa ithemba lemboni elithembisayo. I-Standard gas iyingxube yegesi ene-concen eyaziwa ngokunembile...Funda kabanzi -
Ngaphambilini yayisetshenziselwa ukuqhumisa amabhaluni, i-helium manje isingesinye sezinsiza eziyivelakancane emhlabeni. Iyini ukusetshenziswa kwe-helium?
I-Helium ingelinye lamagesi ambalwa alula kunomoya. Okubaluleke nakakhulu, izinzile, ayinambala, ayinaphunga futhi ayinabungozi, ngakho-ke kuyisinqumo esihle kakhulu ukuyisebenzisela ukuqhumisa amabhaluni azihambelayo. Manje i-helium ivame ukubizwa ngokuthi "igesi engavamile yomhlaba" noma "igesi legolide". I-Helium ...Funda kabanzi -
Ikusasa Lokubuyiswa Kwe-Helium: Izinto Ezintsha Nezinselele
I-Helium iwumthombo obalulekile wezimboni ezihlukahlukene futhi ibhekene nokushoda okungaba khona ngenxa yokutholakala okulinganiselwe kanye nesidingo esikhulu. Ukubaluleka kwe-Helium Yokubuyisela I-Helium ibalulekile ezinhlelweni zokusebenza kusukela ekucabangeni kwezokwelapha nokucwaninga kwesayensi kuya ekukhiqizeni nasekuhloleni indawo....Funda kabanzi -
Ayini amagesi aqukethe i-fluorine? Ayini amagesi akhethekile aqukethe i-fluorine? Lesi sihloko sizokukhombisa
Amagesi akhethekile kagesi ayigatsha elibalulekile lamagesi akhethekile.
