Izici kanye nokusetshenziswa kwe-ethylene
Ifomula yamakhemikhali yi-C2H4. Iwuhlobo oluyisisekelo lwamakhemikhali olusetshenziswa kumafayibha okwenziwa, irabha yokwenziwa, amapulasitiki okwenziwa (i-polyethylene ne-polyvinyl chloride), kanye ne-ethanol yokwenziwa (utshwala). Iphinde isetshenziswe ekwenzeni i-vinyl chloride, i-styrene, i-ethylene oxide, i-acetic acid, i-acetaldehyde, kanye nokukhipha...Funda kabanzi -
I-Krypton iwusizo kakhulu
I-Krypton iyigesi engenambala, engenaphunga, engenambitheki, cishe inzima kabili kunomoya. Ayisebenzi futhi ayikwazi ukushisa noma ukusekela ukusha. Okuqukethwe kwe-krypton emoyeni kuncane kakhulu, kune-krypton engu-1.14 ml kuphela kuyo yonke i-1m3 yomoya. Ukusetshenziswa kwe-krypton embonini I-Krypton...Funda kabanzi -
I-xenon emsulwa kakhulu: kunzima ukuyikhiqiza futhi ayinakushintshwa
I-xenon emsulwa kakhulu, igesi engasebenzi kahle enokuhlanzeka okungaphezu kuka-99.999%, idlala indima ebalulekile ekuthathweni kwezithombe zezokwelapha, ekukhanyiseni okuphezulu, ekugcinweni kwamandla nakwezinye izinkambu ngezindawo zayo ezingenambala nephunga, ukuminyana okuphezulu, izinga lokubila eliphansi kanye nezinye izakhiwo. Njengamanje, imakethe ye-xenon emsulwa kakhulu emhlabeni...Funda kabanzi -
Kuyini i-silane?
I-Silane iyinhlanganisela ye-silicon ne-hydrogen, futhi yigama elijwayelekile lochungechunge lwama-compound. I-Silane ihlanganisa kakhulu i-monosilane (SiH4), i-disilane (Si2H6) kanye namanye ama-compound e-silicon hydrogen asezingeni eliphezulu, ngefomula ejwayelekile i-SinH2n+2. Kodwa-ke, ekukhiqizweni kwangempela, ngokuvamile sibhekisela kuma-monos...Funda kabanzi -
Igesi ejwayelekile: itshe lesisekelo lesayensi kanye nemboni
Ezweni elikhulu locwaningo lwesayensi kanye nokukhiqizwa kwezimboni, igesi ejwayelekile ifana neqhawe elithule ngemuva kwezigcawu, idlala indima ebalulekile. Ayigcini nje ngokuba nezinhlelo zokusebenza eziningi, kodwa futhi ikhombisa ithemba elithembisayo embonini. Igesi ejwayelekile iyinhlanganisela yegesi enomcabango owaziwa kahle...Funda kabanzi -
Ngaphambilini yayisetshenziselwa ukuqhumisa amabhaluni, i-helium manje isibe ngenye yezinsiza ezintuleka kakhulu emhlabeni. Iyini ukusetshenziswa kwe-helium?
I-Helium ingenye yamagesi ambalwa alula kunomoya. Okubaluleke kakhulu, izinzile impela, ayinambala, ayinaphunga futhi ayinangozi, ngakho-ke kuyisinqumo esihle kakhulu ukuyisebenzisa ukuqhuma amabhaluni azintantayo. Manje i-helium ivame ukubizwa ngokuthi “igesi elingavamile” noma “igesi legolide”. I-Helium ...Funda kabanzi -
