Cov tshuaj tiv thaiv xav tau ib tug npaum li cas ntawm lub zog thiaj li yuav tshwm sim . Yog tias lawv tsis muaj, oh zoo, lub tshuaj tiv thaiv tej zaum ua tau 't tshwm sim . A catalyst txo tus nqi zog xav tau kom a tshuaj tiv thaiv tuaj yeem tshwm sim ntau dua yooj yim. Lub zog xav tau ua ib tshuaj tiv thaiv tshwm sim hu ua lub zog ua kom muaj zog.
Hauv qhov no, puas siv cov catalysts?
A catalyst tsis tau siv li nyob rau hauv cov tshuaj tiv thaiv, ho. Zoo li ib tug wingman, nws txhawb nqa lwm cov molecules los teb. Thaum lawv ua, nws nyo hau tawm. Enzymes yog biology's natural catalysts.
Tsis tas li ntawd, vim li cas peb thiaj xav tau catalysts? Catalysts ua kom muaj tshuaj lom neeg los ntawm kev txo qis zog ntawm koj xav tau kom tau ib mus. Catalysis yog lub caj qaum ntawm ntau cov txheej txheem kev lag luam, uas siv cov tshuaj lom neeg los hloov cov ntaub ntawv raw rau hauv cov khoom muaj txiaj ntsig. Catalysts yog ib qho tseem ceeb hauv kev ua cov yas thiab ntau lwm yam khoom tsim.
Tom qab ntawd, yuav ua li cas tshwm sim rau lub catalyst siv hauv cov tshuaj tiv thaiv?
A catalyst ua kom muaj tshuaj lom neeg tshuaj tiv thaiv , tsis tau noj los ntawm cov tshuaj tiv thaiv . Nws nce lub tshuaj tiv thaiv tus nqi los ntawm kev txo qis lub zog ua kom a tshuaj tiv thaiv.
Vim li cas Catalysts ua kom cov tshuaj tiv thaiv?
A catalyst nce tus nqi ntawm cov tshuaj tiv thaiv vim: Lawv muab lwm txoj hauv kev siv hluav taws xob uas muaj lub zog ua kom qis dua. Qhov no txhais tau hais tias ntau cov khoom muaj qhov ua kom lub zog xav tau rau lub tshuaj tiv thaiv coj qhov chaw (piv rau tsis muaj catalyst ) thiab lwm yam ceev ntawm tshuaj tiv thaiv nce.

Dab tsi yog qhov tseem ceeb ntawm kev tawm hauv cov crystal kev loj hlob tsis muaj kev cuam tshuam?
Nws yog ib qho tseem ceeb uas yuav tsum tau ua kom qhov kev sim npog kom tsis txhob muaj plua plav thiab lwm yam khoom siv tsis xav tau los ntawm kev cuam tshuam kev loj hlob siv lead ua. Saib xyuas kev tsim cov muaju ntawm cov hlua txhua hnub. Sab laug tsis muaj kev cuam tshuam, cov muaju yuav tsum loj dua txhua hnub kom txog thaum cov tshuaj qhuav qhuav
Puas muaj cov poov tshuaj ntau dua li neon muaj lossis tsis yog?
Potassium muaj pes tsawg tus electrons ntau dua Neon
Dab tsi yog qhov txawv ntawm kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam cuam tshuam?
Paub qhov txawv ntawm kev cuam tshuam kev tsim kho thiab kev cuam tshuam puas tsuaj. Kev tsim kev cuam tshuam tshwm sim thaum lub crests ntawm ob nthwv dej ntxiv ua ke. Kev cuam tshuam kev puas tsuaj tshwm sim thaum lub crest ntawm ib yoj raug txo los ntawm lub trough ntawm lwm tus
Puas yog cov kev cuam tshuam cuam tshuam ib txwm endothermic?
Cov txheej txheem ntawm dissolving yog endothermic thaum tsawg zog tawm thaum dej molecules "daim ntawv cog lus" rau cov kuab tshuaj dua yog siv los rub cov kua sib nrug. Vim tias lub zog tsawg dua yog tso tawm ntau dua li siv, cov molecules ntawm cov tshuaj txav qeeb dua, ua rau qhov kub thiab txias
Dab tsi yog qee qhov piv txwv ntawm kev cuam tshuam tsis zoo ntawm tib neeg ib puag ncig kev cuam tshuam?
Kev ua liaj ua teb tuaj yeem cuam tshuam tsis zoo rau peb ib puag ncig, suav nrog kev poob ntawm biodiversity, dej paug, kev hloov pauv huab cua, av yaig thiab muaj kuab paug
