Iqhekeza Mass? Kwaye yintoni kanye-kanye?

Ngexesha indlela yemichiza ayisoloko kwenzeka oko kwakubekwe ezicwangcisiweyo, ubuncinane nangokobungakanani. Ngokuqhelekileyo, oku kubangelwe iimeko asabela Kyea - nonideal ubushushu zoqhagamshelwano ezaneleyo kunye kuvala kunye nezinto zokwenza ngokutsha imichiza ukungcola nje. Kulo mzekelo, i ekhemisi zisebenzisa ibinzana elithi "iqhezu ubunzima kwemveliso."

Le ibandakanya ixabiso ethile - pesenti ngokoqobo efunyenwe ngokunxulumene koko kufuneka ukuba afakwe uvule. Otyunjwe ileta "omega". Eli xabiso kufuneka ziqwalaselwe, abafundi baye bakhohlwe ukubala inani elincinane. Ingakumbi, ukungazi phezu iintlobo ezahlukeneyo zovavanyo - uloliwe yokucinga ichanekile, yaye uvavanyo standard wayeza ivumele uninzi lamanqaku umsebenzi ukubala - kwaye kuvavanyo kwi ezinjalo zochuku "catch". Nokuba banikwe ithuba lokukhetha kuthathelwa ingqalelo impendulo yemposiso enjalo. Kulula ukuba abanjwe. Ngoko ke ngaphambi kokuba ukusombulula ingxaki, khangela - nokuba i parameter "iqhekeza abaninzi kwemveliso."

Kukho nezinye, izinto ezifanayo egudileyo. Igama elithi "iqhekeza mass" zinokudityaniswa namanye amagama. Kwaye emva koko wafumana, umzekelo, ipesenti kwezinto kule nsimbi. Oko kukuthi, ukuba isiqwenga izinto apho kuphela inxalenye ethile kungaba asabela. Kwaye kufuneka zithathelwe ingqalelo izibalo, okanye umngcipheko awuphephe umgibe, kwakunye ingqiqo ka "iqhekeza abaninzi kwemveliso." abaninzi kakhulu bayabanjwa baze ngempumelelo. Isilumkiso!

Le meko iye inxalenye ubunzima element kwingxubevange? Oku kuthetha ukuba athom zayo zenza inxalenye ethile ngokobunzima ngoqobo. Enyanisweni, ekhemisi nabathandi izisombululo ezimbaxa iqhezu mass kunokuba luncedo ukuba ukubala kwizibalo yokusabela. Enye ukubaluleka kwalo kwaziswa kungaba, ukuba ufuna ukucwangcisa i formula kweziyobisi. Nje qaphela - kukho into-isomers kunye nezinto kunye nefomula efanayo ngokulinganayo. Wena ukuseka indlela ngqo kuya kufuneka basabele imichiza. Kodwa hayi kwinqanaba lesikolo eso, kwaye ukhuphiswano chemistry.

Eneneni, kudla ngokuba bonke imisebenzi lula kakhulu, abafundi bavavanywa ukuze ulwazi olungumgubo cebetshu nokukwazi ukwenza imisebenzi elula zemathematika, singalibalanga izixa atomic molecule nganye. Njani na ukubala iqhezu ubunzima element? Ngokutsho etafileni, afumane ubunzima atomic le element ofunekayo, phinda ngenani ngqo athom kwi molecule. Lo elingezantsi. Yaye kwinani elingaphezulu kufuneka ubunzima beemolekyuli of yonke unit osisiqu kwifomula, oko kukuthi isiqalelo yakho iimeko ekunene kunye nazo zonke ezinye izinto kunobukhulu liphindaphindwe ngenani kwi molecule. Umzekelo, ubunzima molecule ye zinemoletyhule yamanzi - 16 (oksijini), dibanisa wehydrogen atom (1 + 1). Iyonke 18. Ubunzima iqhezu hydrogen sakhi ilula: yahlula 2 na18.Pri kufuneka phinda ngo nekhulu ekhulwini, kodwa kwakhona ungaboniswa njenge lokugqibela. Ngu mfanekiso uze wenze neefomula ezintsonkothileyo, xa izinto ezintathu okanye ngaphezulu.

iqhezu Mass le mbono nobhaliweyo izisombululo. Inani elingezantsi - mass onyibilikisiweyo, elingezantsi - ubunzima wesinyibilikisi kunye ubunzima iyapheliswa.

Ukuba uhlawula ingqalelo uze uqonde nganye kwezi meko kunokwenzeka, awuna negama phawu. Kanjalo musani ukuba buhlungu ngenxa ingongoma eliphantsi xa yonke kubonakala ukuba isonjululwe, yaye ngaba isiphumo singesiso wonwabile. Nje ungaphoswa la magama iintlobo. Study kunye nokwenza imisebenzi ethile. Xa nabete isandla, yonke iya kuba ngaphambili.
