Cov molecules ntawm ib hom yog tag nrho tus ib yam . Piv txwv li, dej molecules yog tag nrho tus ib yam . Lawv tag nrho muaj ob lub hydrogen atoms thiab ib tug oxygen atom. Cov atoms yuav tsum tau koom nrog txoj kev no los ua ib qho dej molecule.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog dej molecule?
Cov dej molecule yog qhov yooj yim heev. A molecule yog ib qho teeb meem uas muaj ob lossis ntau lub atoms. Nws hu ua H2O vim nws muaj ob lub atom ntawm hydrogen (H) thiab ib lub atom ntawm oxygen (O). Muaj ntau lab ntawm cov no molecules hauv ib poob dej . Daim ntawv dej yuav siv sij hawm nyob ntawm lub zog ntawm lub dej molecules.
Tsis tas li ntawd, dab tsi yog dej molecules ua los ntawm? Txhua yam yog ua los ntawm atoms. Ib qho atom yog qhov tsawg tshaj plaws ntawm cov khoom, xws li oxygen lossis hydrogen. Atoms koom ua ke los tsim molecules . A dej molecule muaj peb atoms: ob hydrogen (H) atoms thiab ib tug oxygen (O) atom.
Dhau li ntawm no, peb puas tuaj yeem pom cov dej molecules?
Dej muaj cov khoom me me hu ua molecules . Koj ua tau 't saib lawv, tsis txawm nyob rau hauv lub microscope, lawv muaj ntau me dua li ntawd. Tab sis txawm txhua dej molecule muaj dua cov me me hu ua atoms.
Muaj pes tsawg hom dej muaj nyob rau hauv chemistry?
Muaj ob hom dej , thiab kev tshawb fawb tshiab pom tias lawv coj txawv txawv. Tsis yog poets xwb. Chemists kuj nyiam siv lyrical txog dej , vim tsis muaj dab tsi zoo li nws.

Puas yog tag nrho cov electromagnetic tsis muaj qhov ceev tib yam hauv lub tshuab nqus tsev?
Electromagnetic hluav taws xob yog ib hom hluav taws xob uas feem ntau hu ua lub teeb. Feem ntau hais lus, peb hais tias lub teeb mus rau hauv nthwv dej, thiab tag nrho cov hluav taws xob hluav taws xob hluav taws xob mus rau tib qhov ceev uas yog li 3.0 * 108 meters ib ob los ntawm lub tshuab nqus tsev
Vim li cas nws yog ib lub tswv yim zoo los cawm tag nrho cov txheej txheem ntawm koj cov extraction kom txog thaum kawg ntawm kev sim?
Kev ua yuam kev thaum lub sijhawm rho tawm (piv txwv li nqa nrog cov txheej txheem tsis raug), tuaj yeem daws tau yog tias cov kev daws tsis tau muab tso rau hauv lub thawv pov tseg! Cov khaubncaws sab nraud povtseg yuav tsum tau txais kev cawmdim kom txog thaum tom qab evaporation vim hais tias cov khoom xav tau yuav tsis soluble heev hauv cov kuab tshuaj siv
Tus naj npawb twg tsis zoo ib yam ntawm cov lej ntuj thiab cov lej tag nrho?
Zero tsis muaj qhov zoo lossis qhov tsis zoo. Txawm li cas los xij, xoom yog suav tias yog tus lej tag nrho, uas ua rau nws ua tus lej, tab sis tsis tas yuav yog tus lej ntuj
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Ntau npaum li cas ntawm cov pej xeem hauv ntiaj teb nyob ntawm cov kab ke roob rau tag nrho lossis qee qhov ntawm lawv cov dej?
Roob yog lub ntiaj teb "dej yees," muab 60-80% ntawm tag nrho cov dej tshiab rau peb ntiaj chaw. Tsawg kawg ib nrab ntawm lub ntiaj teb cov pej xeem nyob ntawm roob ecosystem kev pabcuam kom muaj sia nyob - tsis yog dej xwb, tab sis kuj muaj zaub mov thiab lub zog huv
