Kev sib npaug ntawm cov tshuaj tiv thaiv combustion yog ib qho yooj yim

  1. Ua ntej, tshuav nyiaj li cas carbon thiab hydrogen atoms ntawm ob sab ntawm lub kev sib npaug .
  2. Ces, tshuav nyiaj li cas cov pa oxygen atoms.
  3. Thaum kawg, tshuav nyiaj li cas txhua yam uas tau dhau los ua tsis sib npaug.

Tsis tas li cov lus nug yog, dab tsi yog cov khoom ntawm cov khoom tsis tiav combustion?

Tsis tiav combustion kuj yog ib qho tshuaj tiv thaiv ntawm oxygen thiab roj tab sis cov khoom yog carbon monoxide , dej thiab carbon. Tsis tiav combustion tshwm sim thaum cov tshuaj tiv thaiv combustion tshwm sim tsis muaj cov khoom txaus txaus oxygen.

Qhov thib ob, koj yuav piav qhia txog qhov tshwm sim combustion li cas? A combustion tshuaj tiv thaiv (feem ntau hu ua hlawv) yog exothermic tshuaj tiv thaiv nyob rau hauv uas ib yam dab tsi reacts nrog oxygen. Cov combustion ntawm cov organic tebchaw feem ntau siv cov organic compound + oxygen => dej + carbon dioxide.

Kuj tseem yuav paub yog, dab tsi yog qee qhov piv txwv ntawm lub neej tiag tiag ntawm cov tshuaj tiv thaiv combustion?

Qhov kub ntawm thee los yog ntoo kom sov koj lub tsev, foob pob hluav taws, propane hauv cov roj grills, roj av hauv tsheb, thiab hlawv hluav taws hauv qhov cub hluav taws.

Koj paub li cas cov tshuaj tiv thaiv combustion?

Cov tshuaj tiv thaiv combustion : Txheeb xyuas qhov sib tov los ntawm tshwj xeeb reactant / khoom nta. Ua ntej, nws muaj molecular oxygen (O2) raws li ib tug reactant, tab sis yeej tsis raws li cov khoom. Lwm cov reactant yog hydrocarbon xws li "C6H6" lossis "C8H10". Dej (H2O) thiab carbon dioxide (CO2) yog cov khoom ntawm a combustion tshuaj tiv thaiv.
