Umxholo
Xa uthetha ngemixube, into ebhaliweyo yenziwe ngokubanzi ku iikhompawundi zemichizaOko kukuthi, e Izinto ezenziwa ngamachiza amabini okanye nangaphezulu adibana ngendlela ethile nomlinganiselo.
Inkqubo ye- iipropathi ze-physico-chemical iikhompawundi azifani nezo zemichiza ezenza ngokwahlukeneyo.
Kukho amawaka emizekelo yeekhemikhali ezisingqongileyo, yendalo kunye nokwenziwa, nganye ineempawu zayo. Kusuka kwitafile yetyuwa okanye iswekile esitya ngayo oko sikutyayo yonke imihla, okanye isepha kunye neblitshi esisebenzisa ukuyicoca, kumayeza esiwathathayo ukunciphisa iintlungu zethu okanye ukuzinyanga izifo zethu zenziwe ngamachiza ahlukeneyo.
Ukwahlulahlula
Kuba zininzi izinto zeekhemikhali, kuyinto eqhelekileyo ukuzama ukuzilungiselela ngandlela thile. Ngokubanzi, bahlukaniswe ngamaqela amabini amakhulu: iikhompawundi eziphilayo kunye nezinto ezingaphiliyo:
- Izinto eziphilayoZine okungenani i-carbon kunye ne-hydrogen kwimolekyuli yazo, phakathi kwazo kukho izinto ezibalulekileyo ezinje hydrocarbon, izibaso zakudala; iiproteni okanye amafutha.
- Ezingaqhelekanga: Azinayo ikhabhoni njengeyona nto iphambili, kodwa zidibanisa ezinye izinto (ezinjenge-nitrogen, isulfure, i-iron, i-oksijini okanye i-potassium), ukwenza iityuwa, iioksidi, iihydroxidekunye neeasidi. Ngapha koko intambo icacisa ukuba zikhona neetyiwa kunye neeacidi eziphilayo.
Kuxhomekeke kuhlobo lobophelelo olwenzeka phakathi kwezinto, unokuba ne-ionic okanye i-covalent compounds:
- Ionic iikhompawundi: Zibanjelwe kunye yi-cation kunye ne-anion ngumtsalane obangelwe ngumahluko kwityala.
- Iimpawu ezihlanganayo: Ii-electron zayo kwabelwana ngazo.
Iimpawu zeekhemikhali zihlala zimelwe ngabo ifomula yolwakhiwo okanye iphuhlisiwe. Zikwanceda kakhulu ekuqondeni ukuba zenziwa njani iikhompawundi zemichiza. iimodeli-ntathu, ngakumbi ukuba ziimolekyuli ezintsonkothileyo ezineefolda ezithile, ezinje ngeeproteni.
Ingakukhonza:
- Imizekelo yeeKhemikhali
Imizekelo yeemichiza
Ezinye izinto zeekhemikhali zidweliswe apha ngezantsi:
