Alkane hlawv nrog xiav los yog huv nplaim taws vim tsis tiav combustion ntawm saturated hydrocarbon hauv huab cua..
Hais txog qhov no, vim li cas alkanes hlawv nrog xiav lossis nplaim taws?
Alkanes feem ntau kub hnyiab nrog qhov tseeb nplaim taws . Lawv hlawv hauv av a xiav thiab tsis-sooty nplaim taws raws li qhov feem pua ntawm cov pa roj carbon alkane yog qhov tsawg thiab nws tau oxidized tag nrho hauv huab cua thiab yog vim li cas nws kub hnyiab nrog qhov tseeb nplaim taws.
Vim li cas alkenes hlawv nrog hluav taws kub? Unsaturated hydrocarbons zoo li ethyl, tseem hu ua acetylene, hlawv ua kom daj, nplaim taws vim tsis tiav combustion nyob rau hauv cov huab cua. Cov nplaim taws yog sooty vim qhov feem pua ntawm cov pa roj carbon yog sib piv siab dua li ntawm alkanes thiab thiaj li ua tsis tau oxidized kiag li hauv huab cua.
Ib yam li ntawd, tib neeg nug, vim li cas cov saturated compounds hlawv nrog cov nplaim xiav?
Ans. Saturated hydrocarbons muaj cov ntsiab lus tsawg dua cov pa roj carbon monoxide, yog li muaj kev sib xyaw ua tiav ntawm cov no tshuaj sib xyaw thiab yog li ntawd, cov no compounds hlawv nrog a nplaim taws xiav . Yog li cas tsis saturated hydrocarbons, vim lawv cov ntsiab lus carbon siab thiab cov ntsiab lus tsis tshua muaj hydrogen, muaj cov combustion tsis tiav.
Vim li cas peb hlawv alkanes?
Yooj yim hydrocarbon organic molecules, alkanes , yog chains thiab rings ntawm carbon atoms saturated nrog hydrogens. Hydrocarbons tuaj yeem hlawv tag nrho kom muab carbon dioxide thiab dej. Cov tshuaj tiv thaiv no yog heev exothermic.

Vim li cas cov hluav taws xob sab nraud tsuas yog suav nrog hauv daim duab kos duab hluav taws xob?
Atoms nrog 5 los yog ntau tshaj valence electrons tau electrons tsim ib tug tsis zoo ion, los yog anion. Vim li cas thiaj li cov hluav taws xob sab nraud tsuas yog cov uas suav nrog hauv daim duab orbital filling? lawv tsuas yog cov uas koom nrog cov tshuaj tiv thaiv thiab kev sib raug zoo. 2s orbital nyob deb ntawm lub nucleus txhais tau tias nws muaj zog ntau dua
Vim li cas nws nyuaj rau txheeb xyuas cov hlau ions los ntawm Xim ntawm nplaim taws?
Lub zog no raug tso tawm raws li lub teeb, nrog cov yam ntxwv nplaim xim ntawm cov hlau ions sib txawv vim qhov sib txawv ntawm cov hluav taws xob hloov pauv. Raws li tau hais, cov kev sim no ua haujlwm zoo dua rau qee cov hlau ions dua li lwm yam; tshwj xeeb, cov ions pom nyob rau hauv kab hauv qab ntawm cov infographic feem ntau yog faus thiab nyuaj rau qhov txawv
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Vim li cas saturated hydrocarbons hlawv nrog nplaim taws?
Tam sim no kaw lub qhov cua kom tiav. Unsaturated hydrocarbons zoo li ethyne, tseem hu ua acetylene, hlawv kom tsim daj, sooty nplaim vim tsis tiav combustion hauv huab cua. Cov nplaim yog sooty vim tias feem pua ntawm cov pa roj carbon sib piv siab dua li ntawm alkanes thiab yog li tsis tau oxidized tag nrho hauv huab cua
Lub ntuj puas xiav vim dej hiav txwv los yog dej hiav txwv xiav vim lub ntuj?
'Lub hiav txwv zoo li xiav vim liab, txiv kab ntxwv thiab daj (ntev wavelength teeb) yog absorbed ntau zog los ntawm dej tshaj yog xiav (luv wavelength light). Yog li thaum lub teeb dawb ntawm lub hnub nkag mus rau hauv dej hiav txwv, nws feem ntau yog xiav uas tau rov qab los. Ib yam li ntawd, lub ntuj xiav.'
