Acetylene (lub npe systematic: ethyl) yog tus tshuaj compound nrog cov qauv C2H2 . Nws yog hydrocarbon thiab qhov yooj yim alkyne. Cov roj uas tsis muaj xim no yog dav siv los ua roj thiab a tshuaj tsev thaiv. Nws tsis ruaj khov nyob rau hauv nws daim ntawv ntshiab thiab yog li feem ntau yog daws raws li kev daws teeb meem.
Ib yam li ntawd, nws tau nug, lub npe tshuaj rau c2h2 yog dab tsi?
Ethyne
Kuj Paub, yog c2h2 gas? Acetylene yog cov tshuaj sib xyaw nrog cov mis C2H2 . Nws yog ahydrocarbon thiab qhov yooj yim alkyne. Qhov no tsis muaj xim gas yog dav siv los ua afuel thiab tshuaj lom neeg lub tsev thaiv. Nws yog unstable nyob rau hauv nws daim ntawv ntshiab thiab yog li isusually tuav raws li ib tug tov.
Qhov thib ob, c2h2 sawv cev rau dab tsi?
Ib qho tsis muaj xim, kub heev los yog tawg, C2H2, siv rau hlau vuam thiab txiav thiab ua ib qho illuminant. Kuj hu ua ethin.
C2h2 tsim li cas?
Hauv tsim ntawm C2H2 , carbon atom xav tau electrons ntxiv rau daim ntawv 4 bonds nrog hydrogen thiab lwm yam carbon atoms. Raws li qhov tshwm sim, ib qho 2s2 khub tsiv mus rau qhov khoob 2pz orbital. Lub 2s orbital nyob rau hauv txhua carbon hybridizes nrog ib qho ntawm 2p orbitals thiab tsim ob sp hybrid orbitals.

Dab tsi yog PV hauv Chemistry?
Robert Boyle pom PV = qhov tsis tu ncua. Ntawd yog, cov khoom ntawm lub siab ntawm cov roj lub sij hawm lub ntim ntawm cov pa roj yog acconstant rau ib qho piv txwv ntawm cov roj. Hauv Boyle qhov kev sim ntsuas kub (T) tsis hloov, thiab tsis muaj pes tsawg tus moles (n) ofgas tam sim no
Dab tsi yog qhov txawv ntawm cov chemistry thiab organic chemistry?
Organic chemistry yog suav tias yog ib qho kev qhia ntawm chemistry. Thaum lub sij hawm lub kaus dav dav 'chemistry' yog kev txhawj xeeb nrog kev sib xyaw thiab kev hloov pauv ntawm txhua yam teeb meem, cov khoom siv tshuaj lom neeg tsuas yog txwv rau kev kawm ntawm cov organic tebchaw xwb
John Dalton qhov kev ua tiav tseem ceeb hauv chemistry yog dab tsi?
John Dalton FRS (/ˈd?ːlt?n/; 6 Cuaj hlis 1766 – 27 Lub Xya hli ntuj 1844) yog ib tug Askiv chemist, physicist, thiab meteorologist. Nws paub zoo tshaj plaws rau kev qhia txog atomic txoj kev xav rau hauv chemistry, thiab rau nws txoj kev tshawb fawb rau hauv qhov muag tsis pom xim, qee zaum hu ua Daltonism hauv nws txoj kev hwm
Hooke's Law hauv chemistry yog dab tsi?
CHEMISTRY GLOSSARY Hooke txoj cai hais tias lub cev deformation yog proportional rau qhov loj ntawm deforming quab yuam, muab hais tias lub cev elasticity (saib elasticity) tsis tshaj. Yog tias qhov txwv tsis pub ncav cuag, lub cev yuav rov qab mus rau nws qhov qub qub thaum lub zog raug tshem tawm
Dab tsi yog txoj cai cais tawm hauv chemistry?
Pauli Exclusion Principle hais tias, hauv anatom lossis molecule, tsis muaj ob lub tshuab hluav taws xob tuaj yeem muaj tib tus lej plaub hauv quantum. Raws li lub orbital tuaj yeem muaj qhov siab tshaj plaws ntawm ob lub electrons, ob lub electrons yuav tsum muaj opposingspins
