Tag nrho tshuaj tiv thaiv koom ob leeg reactants thiab cov khoom . Reactants yog cov khoom uas pib a tshuaj tiv thaiv , thiab cov khoom yog cov khoom uas tsim nyob rau hauv lub tshuaj tiv thaiv.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog ib tug reactant nyob rau hauv ib tug tshuaj sib npaug?

Cov khoom (s) rau sab laug ntawm xub hauv a tshuaj sib npaug hu ua reactants . A reactant yog ib yam khoom uas muaj nyob rau ntawm qhov pib ntawm ib tshuaj tshuaj tiv thaiv. Cov khoom (s) rau sab xis ntawm lub xub yog hu ua cov khoom. Ib yam khoom yog ib yam khoom uas muaj nyob rau tom kawg ntawm ib tshuaj tshuaj tiv thaiv.

Qhov thib ob, hom tshuaj tiv thaiv kab mob yog dab tsi? Lub ntsiab plaub hom ntawm cov tshuaj tiv thaiv yog kev sib txuas ncaj qha, tsom xam tshuaj tiv thaiv , ib qho kev hloov pauv, thiab kev hloov pauv ob zaug. Yog koj raug nug tsib lub ntsiab hom ntawm cov tshuaj tiv thaiv , nws yog plaub thiab ces yog acid-base los yog redox (nyob ntawm seb leej twg koj nug).

Hais txog qhov no, cov piv txwv ntawm kev sib npaug tshuaj lom neeg yog dab tsi?

A balanced tshuaj sib npaug tshwm sim thaum tus naj npawb ntawm cov atoms koom nrog rau sab reactants yog sib npaug ntawm cov atoms hauv cov khoom sab. Hauv no tshuaj tiv thaiv , nitrogen (N2) reacts nrog hydrogen (H) los tsim ammonia (NH3). Cov reactants yog nitrogen thiab hydrogen, thiab cov khoom yog ammonia.

Ib qho piv txwv ntawm reactant yog dab tsi?

Reactants yog cov khoom pib muaj nyob rau hauv cov tshuaj tiv thaiv uas tau noj thaum lub sij hawm cov tshuaj tiv thaiv los ua cov khoom. Qee cov tshuaj tiv thaiv mus ua kom tiav, ua rau tag nrho cov reactants ua cov khoom. Cov tshuaj tiv thaiv no tau hais tias yog irreversible. Rau piv txwv , hlawv methane hauv oxygen yog irreversible.
