Tsis muaj tshuaj tiv thaiv , tsis muaj dab tsi yuav puas hloov. Atoms yuav nyob atoms. Tshiab molecules yuav tsis tsim. Tsis muaj kab mob ua tau nyob.
Yog li, yuav ua li cas yog tias tsis muaj chemistry?
Yog muaj yog tsis muaj chemistry ces peb ua tsis tau txais kev paub txog ntau yam tshuaj, cov khoom txawm tias nws yog hlau, tsis yog hlau lossis metalloids, atoms, molecules, nucleus. Chemistry yog ib ceg loj. Tshwj xeeb suav nrog peb ntu tseem ceeb-lub cev chemistry , inorganic chemistry thiab organic chemistry.
Tom qab ntawd, lo lus nug yog, lub neej puas tuaj yeem nyob tsis muaj kev sib txuas? Tsis muaj kev sib xyaw , lub neej raws li peb paub hauv ntiaj teb ua tau tsis yog muaj . 1. Cov tshuaj ib txwm muaj tib lub cev zoo li cov khoom uas lawv tau ua los ntawm.
cov tshuaj thiab tshuaj chemicals tseem ceeb rau lub neej Yog vim li cas los yog vim li cas ho tsis?
A tshuaj tiv thaiv rearrange cov atoms uas ua rau cov reactant los yog reactants. Piav li cas tshuaj thiab tshuaj tiv thaiv yog ib tseem ceeb ib feem ntawm koj lub neej . Vim nws yog ib qho tsim nyog kom muaj sia nyob kom loj hlob. Nws yog tseem ceeb kom peb zom zaub mov hauv peb.
Cov tshuaj lom neeg muaj feem cuam tshuam li cas rau lub neej niaj hnub?
Kev hloov tshuaj lom neeg
- Kev xeb ntawm hlau.
- combustion (kub) ntawm ntoo.
- Cov metabolism hauv cov zaub mov hauv lub cev.
- Sib tov cov kua qaub thiab lub hauv paus, xws li hydrochloric acid (HCl) thiab sodium hydroxide (NaOH)
- Ua noj qe.
- Digesting qab zib nrog amylase hauv qaub ncaug.
- Sib tov baking soda thiab vinegar los tsim cov pa roj carbon dioxide.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Yuav ua li cas koj thiaj paub yog tias cov tshuaj tiv thaiv redox yog ib nrab?
VIDEO Ib yam li ntawd, redox ib nrab cov tshuaj tiv thaiv yog dab tsi? A ib nrab cov tshuaj tiv thaiv yog tus oxidation los yog txo tshuaj tiv thaiv ib feem ntawm a tshuaj tiv thaiv redox . A ib nrab cov tshuaj tiv thaiv yog tau los ntawm kev xav txog kev hloov hauv oxidation lub xeev ntawm tus kheej cov khoom koom nrog hauv tshuaj tiv thaiv redox .
Puas yog dej tiv thaiv tsis muaj zog tiv thaiv?
Kev sib txhuam yog lub zog tshwm sim los ntawm ob yam khoom sib tsoo ua ke. Huab cua tsis kam thiab dej tsis kam yog hom kev sib txhuam. Lawv hu ua non- contact rog
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
