Thaum ua tiav cov pa roj carbon monoxide thiab hydrogen ua ke nrog oxygen (O2) los tsim carbon dioxide (CO2) thiab dej (H2O). Thaum lub sij hawm tsis tiav combustion ib feem ntawm cov pa roj carbon monoxide yog tsis tiav oxidized ua kua los yog carbon monoxide (CO).
Yuav ua li cas thaum lub sij hawm combustion tiav?
Kev tawg tag tshwm sim thaum muaj cua zoo. Carbon thiab hydrogen atoms nyob rau hauv hydrocarbon roj react nrog oxygen nyob rau hauv ib tug exothermic cov tshuaj tiv thaiv: carbon dioxide thiab dej yog tsim.
Yuav ua li cas los ntawm combustion ntawm fuels?
Tshav Kub Ua Los Ntawm Cov Roj Hluav Taws Xob
Roj tso tawm cov cua sov ntawm kev kub hnyiab: Thaum tshav kub kub combustion yog tag nrho cov cua sov tso tawm thaum cov roj hlawv thaum muaj cov pa ua tiav nrog oxygen. Nws yog tshuaj lom neeg cov tshuaj tiv thaiv uas hydrocarbon hlawv thiab nws tsim carbon dioxide, cua sov thiab dej
Thaum ua kom tiav cov roj combustion?
Combustion tiav thaum 100% ntawm lub zog hauv cov roj tau muab rho tawm Nws yog ib qho tseem ceeb uas yuav tsum siv zog ua kom tiav combustion kom khaws roj thiab txhim kho tus nqi ntawm cov txheej txheem combustion. Yuav tsum muaj cua txaus nyob rau hauv lub combustion chamber kom tiav combustion tshwm sim.
Dab tsi yog qhov tseem ceeb rau kev ua kom tiav cov roj?
Daim duab peb sab hluav taws. Peb yam yuav tsum muaj nyob rau hauv kev sib xyaw kom haum ua ntej ignition thiab combustion tuaj yeem tshwm sim - -- Kub, Oxygen thiab roj. Yuav tsum muaj roj hlawv. … Yuav tsum muaj cua sov (qhov kub ntawm qhov hluav taws xob) pib thiab txuas ntxiv cov txheej txheem combustion.

Puas yog tag nrho cov clad ua nyob rau hauv Suav teb?
Kwv yees li 90% ntawm cov khoom nqa tag nrho-Clad hom yog tsim nyob rau hauv Teb Chaws Asmeskas, hauv Pennsylvania. Qhov seem 10% tsis ua nyob rau hauv Teb Chaws Asmeskas, yog ua hauv Suav teb, Fabkis, thiab Ltalis . Puas yog tag nrho-clad ua nyob rau hauv Tuam Tshoj los yog USA?
Qhov twg yog tag nrho lossis tag nrho?
Koj yuav tsum siv tag nrho nrog cov neeg Asmeskas feem ntau, thiab tag nrho nrog cov neeg tuaj saib Askiv feem ntau. … Ib yam li cov nroog no muaj ob npaug L thiab yog Askiv, tag nrho muaj ob npaug L thiab yog Askiv . txhais tau tias tag nrho?
Vim li cas tag nrho cov txiv hmab txiv ntoo rot nyob rau hauv Lavxias teb sab menyuam roj hmab?
Ua tsaug, muaj ib qho yooj yim to taub piav qhia ntawm no. Cov txiv hmab txiv ntoo lwj yog a "qhov tshwm sim" ntawm "lub ntiaj teb zoo li yaj ntawm nws tus kheej," raws li tus tsim-lub hnub qub Natasha Lyonne qhia Refinery29, thiab tseem muaj kev vam meej thaum kawg .
Nyob rau hauv qhov sib npaug sib npaug rau combustion ntawm butane?
Kev sib xyaw ntawm butane hauv oxygen tsim cov pa roj carbon dioxide thiab dej. C4H10 + O2 → CO2 + H2O . Yuav ua li cas yog qhov sib npaug rau kev ua tiav ntawm propane? Kev sib npaug tshuaj sib npaug rau kev sib txuas ntawm propane yog:
Nyob rau hauv teb rau qhov tuaj txog ntawm acidic chyme nyob rau hauv lub duodenum?
Pab plab hnyuv . theem plab hnyuvtshwm sim hauv duodenum raws li cov lus teb rau cov chyme tuaj txog, thiab nws txo qis kev ua pa ntawm plab los ntawm cov tshuaj hormones thiab lub paj hlwb reflexes . Yuav ua li cas teb rau qhov tuaj txog ntawm acidic chyme hauv duodenum?
