Kev sib npaug ntawm cov tshuaj tiv thaiv combustion yog ib qho yooj yim
- Ua ntej, tshuav nyiaj li cas carbon thiab hydrogen atoms ntawm ob sab ntawm lub kev sib npaug .
- Ces, tshuav nyiaj li cas cov pa oxygen atoms.
- 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.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
