Ethene yog ib qho tsis muaj xim tsis muaj roj nrog lub teeb sweetish tsw. Nws muaj melting point -169oC. Nws muaj kub point -104oC. Nws yog insoluble hauv dej tab sis soluble hauv cawv thiab ether.
Ntxiv mus, dab tsi yog cov yam ntxwv ntawm ethene?
Cov khoom ntawm Ethene (ethylene)
- Cov roj tsis muaj xim ntawm chav sov thiab siab ⚛ Melting point = -169 ° C. ⚛ Kub taw tes = -104 ° C.
- me ntsis qab zib.
- nplaim taws.
- non-polar molecule ⚛ soluble hauv non-polar solvents.
- reactive: qhov chaw nquag yog ob daim ntawv cog lus Piv txwv li, ethene tau nkag mus rau qhov kev sib txuas ntxiv.
Dhau li saum toj no, dab tsi yog kev siv ntawm ethene? Ethene yog siv hauv kev tsim cov ethylene glycol (1, 2-ethanediol) uas yog siv raws li ib tug automotive antifreeze neeg sawv cev thiab ua ib tug precursor rau polymers. Siv hauv kev tsim cov polymers xws li polyethylene (Polythene), polyvinyl chloride (PVC), polyester, thiab polystyrene.
Yog li ntawd, dab tsi yog cov khoom ntawm ethane?
Cov khoom. Ntawm tus qauv kub thiab siab , ethane yog xim tsis muaj xim, tsis muaj ntxhiab tsw. Nws muaj ib kub taw tes ntawm -88.5 ° C (-127.3 ° F) thiab melting point ntawm -182.8 ° C (-297.0 ° F).
ethene qauv yog dab tsi?
C2H4

Dab tsi ntawm cov hauv qab no piav qhia txog qhov sib txawv ntawm ib qho khoom muag tas mus li thiab cov khoom muag raws sij hawm?
Lub sij hawm lub sij hawm tso siab rau ib lub sij hawm lub cev suav ntawm cov khoom muag los txiav txim qhov kawg ntawm cov khoom muag thiab tus nqi ntawm cov khoom muag, thaum lub sij hawm perpetual system ua kom tsis tu ncua ntawm cov khoom seem tshuav
Cov nqe lus ntawm tus nqi ntawm cov khoom tsim khoom yog dab tsi?
Tus Nqi ntawm Cov Khoom Tsim, tseem hu ua COGM, yog lo lus siv hauv kev tswj hwm nyiaj txiag uas hais txog lub sijhawm lossis nqe lus uas qhia tag nrho cov nqi tsim khoom. Nws tsis tsuas yog suav nrog tus nqi ntawm cov ntaub ntawv thiab kev ua haujlwm, tab sis kuj tseem muaj qhov sib txawv thiab txhim kho kev tsim cov nqi ua haujlwm
Dab tsi yog cov khoom noj khoom haus thiab cov khoom noj web piav qhia nrog piv txwv?
Lub saw zaub mov tsuas yog ua raws li ib txoj hauv kev thaum tsiaj nrhiav zaub mov. Piv txwv li: Ib tug hawk noj ib tug nab, uas tau noj ib tug qav, uas tau noj ib tug nas tsuag, uas tau noj nyom. Lub vev xaib zaub mov qhia ntau txoj hauv kev sib txawv ntawm cov nroj tsuag thiab tsiaj sib txuas. Piv txwv li: Ib tug hawk kuj yuav noj nas, squirrel, qav lossis lwm yam tsiaj
Dab tsi yog qhov txawv ntawm cov khoom noj khoom haus thiab cov khoom noj web?
Ob lub vev xaib khoom noj thiab cov khoom noj khoom haus muaj ntau cov kab mob xws li cov neeg tsim khoom thiab cov neeg siv khoom (nrog rau cov decomposers). Qhov txawv: Cov khoom noj khoom haus yog qhov yooj yim heev, thaum lub vev xaib zaub mov yog qhov nyuaj heev thiab muaj ntau cov khoom noj khoom haus. Hauv cov khoom noj khoom haus, txhua lub cev muaj tib tus neeg siv khoom lossis tus tsim khoom
Dab tsi yog qhov txawv ntawm cov neeg siv khoom thiab cov khoom tsim khoom?
Teb: Cov khoom siv yog cov khoom kawg rau kev noj cov neeg siv khoom kawg thaum cov khoom tsim khoom yog cov khoom siv raw rau lwm cov khoom lag luam. Teb: Cov neeg tsim khoom zoo yog ib qho siv los ntawm cov neeg tsim khoom: lub Hoobkas machinery, lub rooj ua haujlwm, cov ntaub ntawv raw thiab lwm yam
