Kev sib npaug tshuaj yog qhov kev xav lossis sau ntawv sawv cev ntawm yam tshwm sim thaum tshuaj lom tshuaj tshwm sim. Txoj cai lij choj ntawm kev txuag huab hwm coj hais tias tsis muaj cov atoms tuaj yeem tsim lossis rhuav tshem hauv cov tshuaj lom neeg, yog li tus naj npawb ntawm atoms hauv cov tshuaj tiv thaiv yuav tsum sib npaug ntawm cov atoms hauv cov khoom. Ua raws phau ntawv qhia no kom paub yuav ua li cas kom sib npaug sib npaug tshuaj.
Kauj ruam
Kauj Ruam 1. Sau qhov sib npaug uas tau muab rau koj
Rau qhov piv txwv no, koj yuav siv:
C3H8 + O2 H2O + COJ2
Kauj Ruam 2. Sau tus naj npawb ntawm cov atoms uas koj muaj ntawm txhua sab ntawm qhov sib npaug
Saib ntawm qhov ntsuas hauv qab no ib sab ntawm txhua lub atom kom pom tus naj npawb ntawm atoms hauv kab zauv.
- Sab laug: 3 carbons, 8 hydrogens, thiab 2 oxygens.
- Sab xis: 1 carbon, 2 hydrogen, thiab 3 oxygen.
Kauj Ruam 3. Ib txwm tso cov tshuaj hydrogen thiab cov pa kom txog thaum qhov kawg ntawm kev suav
Qhov no txhais tau tias koj yuav tsum sib npaug cov pa roj carbon atoms ua ntej.
Kauj Ruam 4. Ntxiv qhov sib npaug ntawm cov pa roj carbon atom ntawm sab xis ntawm qhov sib npaug kom sib npaug nrog 3 carbon atoms ntawm sab laug
C3H8 + O2 H2O + 3CO2
- Cov coefficient 3 nyob rau pem hauv ntej ntawm cov pa roj carbon ntawm sab xis qhia 3 carbon atoms raws li qhov ntsuas qis 3 ntawm sab laug qhia 3 carbon atoms.
- Hauv kev sib npaug tshuaj, koj tuaj yeem hloov qhov sib npaug, tab sis tsis txhob hloov qhov ntsuas qis.
Kauj ruam 5.
Tom ntej no, sib npaug hydrogen atoms.
Koj muaj 8 ntawm sab laug. Yog li koj xav tau 8 ntawm sab xis.
C3H8 + O2 4H2O + 3CO2
- Ntawm sab xis, tam sim no koj tau ntxiv 4 ua qhov sib piv vim tias qhov ntsuas qis hauv qab qhia tias koj twb muaj 2 hydrogen atoms.
- Yog tias koj muab qhov sib npaug ntawm 4 los ntawm qhov ntsuas qis dua 2, koj tau txais 8.
Ua kom tiav los ntawm kev ntsuas cov pa oxygen.
- Txij li thaum koj tau ntxiv cov coefficients rau cov molecules ntawm sab laug ntawm qhov sib npaug, tus lej ntawm cov pa oxygen hloov pauv. Tam sim no koj muaj 4 cov pa oxygen hauv cov dej molecule thiab 6 cov pa oxygen hauv cov pa roj carbon dioxide. Yog tias ntxiv, tag nrho dhau 10 oxygen atoms.
-
Ntxiv qhov coefficient 5 rau cov pa oxygen molecule ntawm sab laug ntawm kab zauv. Tam sim no koj muaj 10 cov pa oxygen molecules ntawm txhua sab.
C3H8 + 5O Nws2 4H2O + 3CO2.
-
Cov pa roj carbon, hydrogen thiab cov pa oxygen sib npaug. Koj qhov sib npaug ua tiav.
Lub tswv yim
Yog tias koj muaj teeb meem, koj tuaj yeem ntaus cov tshuaj sib npaug rau hauv online sib npaug kom sib npaug. Nco ntsoov tias koj yuav tsis muaj kev nkag mus rau tus lej online thaum xeem, yog li tsis txhob vam khom nws
Ceeb toom
Tsis txhob siv cov zauv ua qhov sib koom ua ke hauv kev sib xyaw tshuaj - vim tias koj tsis tuaj yeem ua ib nrab ntawm cov molecule lossis ib nrab ntawm atom hauv cov tshuaj lom neeg tshuaj. Txhawm rau tshem tawm ib feem, muab tag nrho cov kev ua zauv (ob sab laug thiab sab xis) los ntawm tus lej hauv cov lej ntawm koj feem
