Lawv yog siv Raws li cov tub yees, kiv cua rau aerosols, rau tsim cov yas foamed xws li nthuav polystyrene lossis polyurethane ua npuas ncauj, thiab ua cov kuab tshuaj rau kev tu kom qhuav thiab rau lub hom phiaj degreasing.
Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog alkyl halides siv rau?
Alkyl halides yog cov ntau yam sib xyaw ua ke hauv kev lag luam chemical. Me me haloalkanes yog qee qhov feem ntau siv cov kuab tshuaj nyob rau hauv chemical laboratory; chlorofluorocarbons tau pom dav siv li refrigerants thiab propellants; thiab cov tebchaw uas muaj Br thiab F feem ntau siv hauv hluav taws kub retardants.
Qhov thib ob, cov piv txwv ntawm alkyl halides yog dab tsi? Piv txwv ntawm Alkyl Halides Los yog lawv tuaj yeem ua tau zoo li chloroform, uas cov kws kho mob tau siv yav dhau los los pab ua kev phais: Cov alkyl halide ua chloroform. Los yog lawv tuaj yeem ua tau nyuaj, zoo li cov tshuaj lom no uas tuaj yeem pom hauv mussels. Txij li thaum dej hiav txwv muaj ntau halogens nyob rau hauv nws, co toxins, xws li mussel toxin, feem ntau tsim.
Yog li, dab tsi yog kev siv halides?
Kev siv cov Halides
- Halides yog siv nyob rau hauv solder paste. Halogens tau muab tso rau hauv organohalides tebchaw hauv hluavtaws organic chemistry.
- Nws yog dav siv nyob rau hauv hlau halide teeb uas yog high-siv paug tawm teeb.
- Silver halides yog siv rau hauv cov ntaub ntawv thiab phosphoric films.
Dab tsi yog lub cev muaj zog ntawm alkyl halides?
Lub cev muaj zog ntawm alkyl halides
- 1) Ntau yam tsis muaj zog halogen muaj qab zib hauv tsw. 2) Cov tswv cuab qis dua yog cov pa roj & cov tswv cuab siab dua yog cov kua lossis cov khoom khib nyiab.
- 4) Raws li branching nyob rau hauv alkyl halide nce lub boiling point ntawm alkyl halide txo.
- 5) Alkyl halides tau yooj yim soluble hauv cov kuab tshuaj organic tab sis me ntsis soluble hauv dej.

Dab tsi yog lub tswv yim ntawm kev txhawb nqa ntawm kev sib cais ntawm kev sib deev?
Kev txhawb zog yog cov txheej txheem los ntawm kev xaiv ntuj tsim kom muaj kev sib cais ntawm kev sib deev. Kev txhawb zog tuaj yeem tshwm sim raws li hauv qab no: Thaum ob pawg neeg uas tau khaws cia sib nrug, rov qab los rau hauv kev sib cuag, qhov kev sib cais ntawm cov menyuam yaus yuav ua tiav lossis tsis tiav. Yog tias nws ua tiav, speciation tau tshwm sim
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog qhov kev sib raug zoo ntawm kev ua lej ntawm qhov kev nyuaj siab khov kho thiab Mollality?
Kev nyuaj siab qhov chaw khov kho yog cov cuab yeej sib koom ua ke pom hauv cov kev daws teeb meem uas tshwm sim los ntawm kev qhia txog cov kuab tshuaj molecules rau cov kuab tshuaj. Cov ntsiab lus khov ntawm cov kev daws yog tag nrho qis dua li cov kuab tshuaj ntshiab thiab yog ncaj qha proportional rau molality ntawm cov kuab tshuaj
Dab tsi yog qhov teeb meem loj tshaj plaws ntawm kev siv cov kev tshawb fawb txog kev sib raug zoo?
Tej yam tsis zoo los yog kev tshawb fawb txog kev sib raug zoo muaj xws li: a. Lawv tsis tuaj yeem siv los tsim kom muaj kev sib raug zoo-thiab-tshuaj los yog kev coj ntawm kev cuam tshuam
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
