Azide yog lub anion nrog cov qauv N − 3. Nws yog lub hauv paus conjugate ntawm hydrazoic acid (HN3). N − 3 yog ib tug linear anion uas yog isoelectronic nrog CO2, NCO−, N2O, NO +
Kuj paub yog, dab tsi yog azide siv rau?
Sodium azide ua yog qhov zoo tshaj plaws lub npe hu ua tshuaj muaj nyob rau hauv tsheb airbags. Tus nqi hluav taws xob ua rau lub tsheb cuam tshuam ua rau sodium azide ua txhawm rau tawg thiab hloov mus rau cov pa roj nitrogen hauv lub hnab airbag. Sodium azide ua yog siv li ib qho tshuaj preservative hauv tsev kho mob thiab chaw kuaj mob.
Tsis tas li ntawd, vim li cas azide tawg? Azidoazide azide ua yog feem ntau tawg chemical compound puas tau tsim. Nws yog ib feem ntawm cov chav kawm ntawm cov tshuaj hu ua high-nitrogen energetic cov ntaub ntawv, thiab nws tau txais nws "bang" los ntawm 14 nitrogen atoms uas tsim nws nyob rau hauv ib tug xoob khi lub xeev. Cov khoom no yog ob qho tib si reactive thiab heev tawg.
Ua kom pom qhov no, puas yog azide lub hauv paus muaj zog?
Yog li, sodium azide ua yog ib qho nyuaj vim nws yog ib qho ntawm ob peb muaj zog nucleophiles uas tsis muaj zog puag (cov halides kuj ua raws li txoj cai no). Nws yog ib muaj zog nucleophile vim nws muaj cov nqi tsis zoo.
Puas yog azide yog ib pab pawg tawm zoo?
Cov azide ua function yog a zoo tawm pawg zoo ib yam li N-hydroxysuccinimide pab pawg ntawm NHS ester compounds. Kev sib txuas lus nrog ib qho amine pab pawg tshwm sim los ntawm kev tawm tsam ntawm nucleophile ntawm electron-deficient carbonyl pab pawg (Reaction 3.3).

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
