Cov tshuaj sib npaug yuav tsum tau sib npaug kom nws ua raws li txoj cai ntawm kev txuag ntawm huab hwm coj. A balanced tshuaj sib npaug tshwm sim thaum tus naj npawb ntawm cov atoms sib txawv ntawm cov khoom nyob rau hauv lub reactants sab yog sib npaug ntawm cov khoom sab. Sib npaug tshuaj sib npaug yog ib txoj kev sim thiab ua yuam kev.

Nyob rau hauv txoj kev no, qhov sib npaug ntawm cov tshuaj sib npaug yog dab tsi?

A kev sib npaug yog ib kev sib npaug rau a tshuaj tiv thaiv nyob rau hauv uas tus naj npawb ntawm atoms rau txhua lub hauv paus tshuaj tiv thaiv thiab tag nrho cov nqi yog tib yam rau ob qho tib si reactants thiab cov khoom. Kuj Paub Raws li: Sib npaug tus kev sib npaug , sib npaug tus tshuaj tiv thaiv , kev txuag nqi thiab huab hwm coj.

Ib sab saum toj no, yuav ua li cas yog tias qhov sib npaug ntawm cov tshuaj tsis sib npaug? Tshuaj cov tshuaj tiv thaiv yuav tsum yog sib npaug , los yog nyob rau hauv lwm yam lus, yuav tsum muaj tib tus naj npawb ntawm ntau yam atoms nyob rau hauv cov khoom xws li nyob rau hauv cov reactants. Yog tias cov tshuaj tiv thaiv tsis sib npaug , tsis muaj ntaub ntawv hais txog kev sib raug zoo ntawm cov khoom thiab cov reactants tuaj yeem muab tau.

Hais txog qhov no, dab tsi yog cov kauj ruam hauv kev ntsuas tshuaj sib npaug?

Cov kauj ruam

  • Sau koj qhov kev sib npaug. Rau qhov piv txwv no, koj yuav siv:
  • Sau tus naj npawb ntawm atoms rau ib lub caij.
  • Txuag hydrogen thiab oxygen rau qhov kawg, vim lawv feem ntau ntawm ob sab.
  • Pib nrog ib lub ntsiab lus.
  • Siv cov coefficient kom sib npaug ntawm ib qho carbon atom.
  • Ntsuas cov hydrogen atoms tom ntej.
  • Ntsuas cov pa oxygen atoms.

Vim li cas peb thiaj li yuav tsum sib npaug ntawm cov tshuaj sib npaug?

A chemical equation yuav tsum ua sib npaug vim txoj cai tswj kev ruaj ntseg yuav tsum tuav zoo thaum lub sij hawm ib tshuaj sib npaug . Sib npaug ntawm kev sib npaug yog tsim nyog vim atoms tsis yog tsim los yog puas thaum lub sij hawm ib tshuaj sib npaug.
