Ib qho kev sib npaug yog sib npaug thaum tib tus lej ntawm txhua lub ntsiab lus tau sawv cev ntawm cov khoom siv rov ua dua thiab cov khoom lag luam.
Kuv yuav ua li cas sib npaug ntawm cov tshuaj sib npaug?
Yuav kom sib npaug ntawm cov tshuaj sib npaug, koj yuav tsum tau kom paub tseeb tias tus naj npawb ntawm cov atoms ntawm txhua lub ntsiab ntawm cov reactant sab yog sib npaug rau cov atoms ntawm txhua lub ntsiab ntawm cov khoom sab. Txhawm rau ua kom ob sab sib npaug, koj yuav tsum muab cov lej ntawm cov atoms hauv txhua lub caij kom txog thaum ob sab sib npaug.
Yuav ua li cas thaum ntsuas qhov sib npaug?
Thaum koj sib npaug ntawm cov tshuaj sib npaug, koj hloov coefficients. Koj yeej tsis hloov subscripts. Lub coefficient yog tag nrho cov lej sib npaug. Txhawm rau sib npaug ntawm kev sib npaug tshuaj, koj ntxiv tag nrho cov lej sib npaug (coefficients) kom paub tseeb tias muaj tib tus lej ntawm cov atoms ntawm txhua sab ntawm tus xub.
3 txoj cai rau kev sib npaug yog dab tsi?
Summary
- Yuav kom muaj txiaj ntsig, kev sib npaug tshuaj yuav tsum muaj qhov sib npaug. Kev sib npaug tshuaj sib npaug muaj tib tus lej thiab hom ntawm txhua lub atom ntawm ob sab ntawm kab zauv.
- Cov coefficients hauv qhov sib npaug sib npaug yuav tsum yog qhov yooj yim tshaj plaws tus lej piv. Mass yeej ib txwm khaws cia rau hauv cov tshuaj tiv thaiv.
Yuav ua li cas yog shortcut rau balancing equations?
Yog tias tsis muaj qhov tsis sib xws, cov tshuaj sib npaug tau hais kom sib npaug. Hauv qhov piv txwv no, txhua lub ntsiab lus tam sim no muaj tus lej sib npaugatoms nyob rau hauv reactant thiab khoom sab. Yog li, qhov sib npaug tshuaj sib npaug yog C 3 H 8+ 5O2→ 3CO 2 + 4H2O.
