Piv txwv ntawm inorganic carbonyl cov tshuaj yog carbon dioxide thiab carbonyl sulfide. Ib pawg tshwj xeeb ntawm carbonyl Cov tebchaw yog 1, 3-dicarbonyl compounds uas muaj acidic protons nyob rau hauv central methylene unit. Piv txwv yog Meldrum's acid, diethyl malonate thiab acetylacetone.
Tom qab ntawd, ib tug kuj yuav nug, carbonyl pom nyob rau hauv dab tsi?
Carbonyl Cov pab pawg muaj cov pa roj carbon atom ob npaug rau cov pa oxygen. Lawv tuaj yeem yog pom hauv ob peb pawg ua haujlwm sib txawv, xws li aldehydes, ketones, esters, thiab ntau ntxiv. A carbonyl pab pawg tuaj yeem ua rau kom lub melting los yog boiling point ntawm ib tug compound.
Ib tug kuj yuav nug, koj yuav txheeb xyuas cov pawg carbonyl li cas? A carbonyl pawg yog chemically organic ua haujlwm pab pawg tsim los ntawm cov pa roj carbon atom dual-bonded rau oxygen atom [C = O] Qhov yooj yim tshaj plaws carbonyl pawg yog aldehydes thiab ketones feem ntau txuas rau lwm cov pa roj carbon. Cov qauv no tuaj yeem pom nyob rau hauv ntau yam aromatic tshuaj sib xyaw contributing rau tsw thiab saj.
Tom qab ntawd, lo lus nug yog, cov tshuaj carbonyl yog dab tsi?
Lub ntsiab cov tshuaj tiv thaiv ntawm carbonyl pawg yog nucleophilic ntxiv rau carbon-oxygen ob daim ntawv cog lus. Raws li qhia hauv qab no, qhov sib ntxiv no suav nrog ntxiv cov nucleophile thiab hydrogen hla carbon-oxygen ob daim ntawv cog lus. Cov pa roj carbon atom muaj ib nrab nqi zoo, thiab cov pa oxygen atom muaj ib feem tsis zoo nqi.
Tus nqi ntawm carbonyl yog dab tsi?
Properties ntawm carbonyl pawg The carbonyl pawg yog me ntsis polar. Qhov ntawd txhais tau hais tias ib qho kawg ntawm nws (cov pa roj carbon atom) muaj hluav taws xob zoo me ntsis nqi , thiab ib qho kawg ntawm nws (cov pa atom) muaj qhov tsis zoo me ntsis nqi . Qhov no ua rau tag nrho cov molecular ib tug polar molecule.

Ib qho piv txwv ntawm ib qho alloy yog dab tsi?
Ib qho piv txwv ntawm cov hlau yog sib xyaw ntawm cov hlau thiab hlau. Ib qho piv txwv ntawm cov hlau yog cov tin hauv qhov sib xyaw ntawm tooj liab thiab tin uas ua rau tooj liab. Lub alloy yog ib qho fusion ntawm ob lossis ntau dua hlau lossis cov hlau uas tsis yog hlau. Ib qho piv txwv ntawm cov hlau yog tooj dag, uas yog tsim los ntawm tooj liab thiab zinc
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
