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.
