Yini usokhemisi?

Ezinye izikole sebeqala ukufunda ngesayensi yokuthakwa kwamakhemikhali ebangeni 7th, kwabanye kuphela grade 8. Chemistry - kuyinto bezesayensi, kodwa neverotyano ezithakazelisayo futhi ezibalulekile. Abantu namanje abazi konke ngalokhu isayensi. Minyaka yonke, osokhemisi ukuvula eplanethini yethu into entsha.

Ngubani usokhemisi?

Cabangela incazelo imininingwane. Chemist - usosayensi noma uchwepheshe emkhakheni wesayensi yokuthakwa kwamakhemikhali, owathola imfundo ekhethekile. Lezi ososayensi ukutadisha izakhi zamakhemikhali, okungukuthi, isikhundla, udaba futhi izakhiwo zalo. Basebenzisa lwati lolutfolakele ekutadisheni nokuthola izinto ezintsha.

Yezinto ezibaluleke kakhulu emkhakheni wesayensi yokuthakwa kwamakhemikhali

Kwamakhemikhali waphawula amakhulu ezibaluleke, isibonelo, ukuthola isici okufana chemical njengomoya-mpilo, ukutadisha isakhiwo kwamakhemikhali, ukuthola ama-electron, le-radioactivity izakhi ezithile zamakhemikhali, ukudalwa ishadi lesikhathi salezi izakhi nabanye abaningi. Zonke lezi zinto ezatholakala futhi ubelokhu wemithi owaqala ebaxilonga bese ngesisekelo ulwazi aluthola uzama ukwenza iziphetho ezidingekayo bese bethola okuthile eyabo.

bamakhemikhali Russian

bamakhemikhali Russian kungukuthi emuva. Minyaka yonke ngokuya ihogela chemistry biology ekhetha abafundi abaningi.

Russia idume ososayensi, isibonelo, njenge Mikhail Vasilyevich Lomonosov, oye wacwaninga imfundiso yokuziphendukela yamangqamuzana-kinetic, uDmitri Ivanovich Mendeleev ukuthi wadala etafuleni esisemqoka gqwa izakhi zamakhemikhali wabhala ebhukwinitifundvo wokuqala Russian kwemithi organic, uVladimir Markovnikov (uwoyela wafundelwa futhi nezinye izinto eziningi ).

Mhlawumbe usokhemisi odumile kakhulu Russian - lokhu Dmitri Ivanovich Mendeleev, okuyinto abafundi ukukhuluma ngesikhathi izifundo zokuqala kwamakhemikhali. Lokhu wemithi wadala etafuleni ngezikhathi ezithile izakhi, sibonga ngalo chemistry cwaningo lula kakhulu futhi ethengekayo. Ngaphezu kwalokho, wabhala imisebenzi abangamakhulu amaningana, olwenziwa izinkulungwane ucwaningo nocwaningo. Umsebenzi wakhe, abafundi ukufunda emanyuvesi. Kwaphela iminyaka eminingi, uDmitry Ivanovich wasebenza eyunivesithi, lapho ozongitshela ukuthi abafundi elula. Namuhla, bonke imibhalo yakhe - liyinqolobane wangempela wokwazi Wabasaqalayo bamakhemikhali.

Chemistry - kuyinto isihloko nzima kakhulu kodwa kudingeka empilweni yangempela. Chemistry izifundo konke esizungezile esenza ukuba baphila ephasini. Nale isayensi siye safunda okuningi ngeplanethi yethu. Lokhu wemithi kufanele athande lolu isayensi, njalo ukufunda okuthile okusha.
