Methane thiab oxygen (oxygen yog diatomic - ob-atomic - lub ntsiab) yog cov reactants Txawm li cas los xij, carbon dioxide thiab dej yog qhov cov khoom . Tag nrho cov reactants thiab cov khoom yog gases (qhia los ntawm g's hauv kab lus). Hauv cov tshuaj tiv thaiv no, tag nrho reactants thiab cov khoom yog pom tsis tau.

Tib neeg kuj nug, dab tsi yog reactants thiab cov khoom?

Tag nrho cov tshuaj tiv thaiv muaj xws li ob qho tib si reactants thiab cov khoom . Reactants yog cov tshuaj uas pib tshuaj lom neeg, thiab cov khoom yog cov khoom uas tsim tawm hauv cov tshuaj tiv thaiv.

Ib tug kuj yuav nug, dab tsi yog piv txwv ntawm reactants? Piv txwv ntawm Reactants H2 ( hydrogen gas) thiab O2 (oxygen gas) yog reactants nyob rau hauv cov tshuaj tiv thaiv uas ua kua dej: 2 H2(g) + O2(g) → 2 H2O(l). Daim ntawv ceeb toom huab hwm coj tau khaws cia hauv qhov sib npaug no. Muaj plaub atoms ntawm hydrogen nyob rau hauv ob qho tib si reactant thiab khoom sab ntawm qhov sib npaug thiab ob lub atoms ntawm oxygen.

Yog li, dab tsi yog qhov txawv ntawm reactants thiab cov khoom?

Cov tshuaj tiv thaiv feem ntau tshwm sim nruab nrab cov tshuaj uas raug xa mus ua tshuaj reactants . Thaum kawg ntawm cov tshuaj tiv thaiv, reactants feem ntau yog noj thiab hloov mus ua ib yam khoom tshiab. Ntawm qhov tod tes, cov khoom yog cov ntsiab lus kawg ntawm cov tshuaj tiv thaiv, thiab lawv tau tsim thaum kawg ntawm cov txheej txheem.

Cov khoom yog dab tsi?

Cov khoom yog hom tsim los ntawm cov tshuaj tiv thaiv. Thaum lub sij hawm ib tug tshuaj tiv thaiv reactants hloov mus rau hauv cov khoom tom qab dhau los ntawm kev hloov pauv lub zog siab. Cov txheej txheem no ua rau kev noj cov reactants. Cov ntaub ntawv yog reactive thiab reactants yog rearranging thaum muaj tshuaj tiv thaiv.
