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.

Dab tsi yog cov khoom lag luam hauv kev sib npaug molecular rau kev ua tiav cov tshuaj tiv thaiv ntawm aqueous barium hydroxide thiab nitric acid?
Ba(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O. Barium hydroxide react nrog nitric acid los tsim barium nitrate thiab dej
Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Cov coefficients hauv kev sib npaug tshuaj sib npaug qhia koj li cas txog cov reactants thiab cov khoom?
Cov coefficients ntawm kev sib npaug chemicalequation qhia peb cov txheeb ze ntawm moles ntawm reactants thiab cov khoom. Hauv kev daws teeb meem stoichiometric, kev hloov pauv ntawm moles ntawm reactants rau moles ntawm cov khoom raug siv. Hauv kev suav loj, cov molar loj yog xav tau los hloov cov huab hwm coj mus rau moles
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
