Kwesibalo Chemical: kanjani ukubhekana ngokuphumelelayo

Chemical kwesibalo kungenziwa ngokuthi ngeso ukuthi bayavuma amakhemikhali ngezibonakaliso kweTibalo amafomula zamakhemikhali. Lezo iyona ukukhangiswa kwanoma yimuphi ukuphendula ngesikhathi lapho into entsha.

imisebenzi Chemical: Izinhlobo

Chemical sesibalo - ekulandelaneni zamakhemikhali. Zisekelwe umthetho ukulondolozwa mass iyiphi into. Kunezinhlobo ezimbili kuphela izinhlobo ukusabela:

• Compounds - lezi zihlanganisa ukusabela esikhundleni (ama-athomu esikhundleni izakhi eziyinkimbinkimbi elula ngama-athomu reactants), exchange (esikhundleni izingxenye ingxenye izinto ezimbili esiyinhlanganisela), neutralization (acid base ukuphendula, kumiswa usawoti namanzi).
• Kwandzisa - kumiswa ezimbili nolunzima noma elula izinto elilodwa eziyinkimbinkimbi, kodwa isakhiwo sabo lula.

Ukusabela Chemical kungabuye ihlukaniswe izinhlobo: exothermic (ukushisa ukukhululwa zenzeka ne) kanye endothermic (ukushisa iyavuleka).

Indlela ukuxazulula zibalo ka zamakhemikhali

Lo magazini kuyinto ekhathaza abafundi abaningi. Thina predlegaem amathiphu ambalwa alula ukuthi uzokutshela ukuthi ukufunda ukuba uxazulule izibalo chemical:

• Isifiso ukuqonda futhi master. Awukwazi bachezuke umgomo wakhe.
• ulwazi theory. Ngaphandle kwawo akunakwenzeka ukwenza ngisho ifomula olula kwakwakhe.
• Ukuthi lolusuku okuqoshiwe izinkinga chemical - ngisho iphutha kancane esimweni kuzonciphisa ukugxila kwayo yonke imizamo yakho ezinqumweni zawo.

Kuyinto efiselekayo ukuthi inqubo yokuxazulula chemical zibalo kwakumnandi ngawe. Khona-ke ezothando chemical (indlela ukubhekana nazo futhi lokho kukhomba udinga ukukhumbula, sizohlola kulesi sihloko) ngeke usaba khona inkinga ngawe.

Izinkinga ukuthi isixazululekile usebenzisa zamakhemikhali of zibalo

Lezi zinkinga zihlanganisa:

• Ukuthola isisindo ingxenye mass inikezwe lomunye reagent.
• Yokukhonjiwe ukuze inhlanganisela "mass-imvukuzane".
• Izibalo esekelwe inhlanganisela "ivolumu-imvukuzane".
• Izibonelo esebenzisa inkulumo ethi "okungalé".
• Izibalo usebenzisa reagents, enye yazo engalali amanyela.
• Izinselele nokwahlukana umphumela ukusabela kanye nokulahlekelwa ukukhiqizwa.
• Izinselelo ifomula yokusesha.
• Izinkinga lapho reagents zinikezwa njengoba izixazululo.
• Imisebenzi equkethe ingxube.

Ngayinye yalezi imisebenzi kuhlanganisa subtypes eziningana, avame sombiko izogxila kakhulu izifundo esikoleni i-chemistry kuqala.

kwesibalo Chemical: indlela yokubhekana

Kukhona algorithm esisiza ukuba sibhekane ngokuphumelelayo cishe noma yimuphi umsebenzi kule isayensi nzima. Ukuze uqonde indlela yokuxazulula zibalo zamakhemikhali, udinga ukulandela indlela ethile yokuma:

• Lapho uqopha ezothando yokusabela akabakhohlwa ukubeka okuza.
• Ukunquma izindlela lapho ungathola idatha engaziwa.
• isicelo Lungile olinganise ekhethiwe ifomula noma nokusetshenziswa kwegama elithi "inani into".
• Nakani amayunithi wokulinganisa angakahleleki.

Ekugcineni kubalulekile qinisekisa ukubheka inkinga. Ekubhekaneni ungase uvimbele nephutha aphansi lokhu kwathinta yi ngesinqumo.

Imithetho eyisisekelo of zibalo chemical

Uma zithobele kulandzelana lokufanele, bese umbuzo yini ezothando zamakhemikhali, indlela yokuxazulula kubo, ngeke bajabule kuwe:

• Formula izinto angene yokusabela (reactants), zilotshwe ohlangothini lwesobunxele equation.
• Formula izinto akhiwa ukuphendula, kakade ezilotshwe ngakwesokudla of the equation.

Ukulungiselela zibalo ukuphendula ezisekelwe emithethweni ukulondolozwa izinto mass. Ngenxa yalokho, bobabili izingxenye kwesibalo kumele ilingane, isb. E. Nge inani elifanayo ama-athomu. Lokhu kungafezwa, inqobo ukuqondanisa ofanele okuza izinto amafomula.

Lapho umgwaqo i-okuza kule ndaba chemical

ukubekwa algorithm okuza kanje:

• Ukubala ohlangothini lwesobunxele futhi kwesokudla-athomu element ngayinye.
• Ukunqunywa ekushintsheni-athomu ye-elementi. Udinga ukuthola N.O.K.
• Ulungiselela okuza ibangelwa sokuhlukanisa N.O.K. phezu indices. Qiniseka ukuthi babeke phansi lezi zinombolo phambi amafomula.
• Isinyathelo esilandelayo ukuguquka-athomu. Ngezinye izikhathi kudingeka ukuphinda senzo.

Nokulingana izingcezu yokusabela chemical kwenzeka nge okuza. Ukubala of the indices ezivezwa Valence.

Ukuze uphumelele ukumiswa ukuxazulula chemical zibalo kumelwe acabangele Izakhiwo zanoma ndaba, okufana nevolumu, ukuminyana, mass. Kuyadingeka ukwazi isimo uhlelo ukusabela (okuhlushwa, izinga lokushisa, ingcindezi), ukuqonda amayunithi yalezi izinto eziningi.

Ukuze uqonde umbuzo yini ezothando zamakhemikhali, indlela yokuxazulula kubo, udinga ukusebenzisa imithetho eyisisekelo futhi imiqondo kwale sayensi. Ukuze ngempumelelo ukubala izinkinga ezinjalo, futhi kuyadingeka ukukhumbula noma bafundza emakhono imisebenzi zezibalo bakwazi ukwenza imisebenzi ngezinombolo. Sithemba amathiphu ethu kuyoba lula ukubhekana nokukhumbula zibalo zamakhemikhali.
