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)
