Kev txhais ntawm Cov Tshuaj Molecular
Nws yog ib tshuaj molecular ,qus a yam khoom nrog ob lossis ntau lub atoms, qhov tsawg tshaj plaws ntawm cov teeb meem, koom ua ke los ntawm covalent daim ntawv cog lus. Covalent daim ntawv cog lus yog qhov txuas tsim los ntawm kev sib koom ntawm cov hluav taws xob uas tuav cov atoms ua ke.
Hauv qhov no, dab tsi yog qhov yooj yim molecular khoom?
Cov tshuaj molecular yooj yim suav nrog molecules nyob rau hauv uas cov atoms tau koom nrog muaj zog covalent bonds. Txawm li cas los xij, lub molecules tau tuav ua ke los ntawm qaug zog li no tshuaj muaj tsawg melting thiab boiling ntsiab lus. Lawv tsis ua hluav taws xob.
3 piv txwv ntawm molecules yog dab tsi? Piv txwv ntawm Molecules:
- Cov pa roj carbon dioxide - CO2
- Dej - H2O.
- Oxygen peb ua pa rau hauv peb lub ntsws - O2
- Qab Zib - C12H22O11
- Glucose - C6H12O6
- Nitrous oxide - "Laughing gas" - N2O.
- Acetic acid - ib feem ntawm vinegar - CH3COOH. Txuas Txuas: Piv txwv. Piv txwv science.
Ib yam li ntawd, nws yog nug, dab tsi yog molecule thiab piv txwv?
A molecule yog qhov tsawg tshaj plaws nyob rau hauv cov khoom siv tshuaj lossis cov khoom sib xyaw uas muaj cov khoom siv tshuaj lom neeg ntawm cov khoom lossis cov khoom sib xyaw. Piv txwv Ntawm cov ntsiab lus no yog oxygen thiab chlorine. Cov atoms ntawm qee lub ntsiab lus tsis yooj yim sib txuas nrog lwm cov atoms. Piv txwv yog neon thiab argon.
Dab tsi yog cov yam ntxwv ntawm cov khoom yooj yim molecular?
Cov khoom ntawm cov khoom yooj yim molecular
- Tej yam yooj yim molecular tshuaj feem ntau muaj cov ntsiab lus melting tsawg thiab boiling point thiab feem ntau yog kua los yog gases ntawm chav tsev kub.
- Lub zog yog pauv mus rau ib yam khoom kom yaj los yog boil nws.
- Muaj cov rog intermolecular ntawm cov molecules yooj yim.

Dab tsi yog cov khoom lag luam hauv kev sib npaug molecular rau kev ua tiav cov tshuaj tiv thaiv ntawm aqueous barium hydroxide thiab nitric acid?
Ba(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O. Barium hydroxide react nrog nitric acid los tsim barium nitrate thiab dej
Dab tsi yog cov nyhuv tshuaj ntawm hluav taws xob muab qee qhov piv txwv ntawm cov nyhuv tshuaj?
Ib qho piv txwv ntawm cov tshuaj muaj zog hauv cov hluav taws xob tam sim no yog electroplating. Hauv cov txheej txheem no, muaj cov kua dej uas muaj hluav taws xob dhau mus. qhov no yog ib qho piv txwv ntawm kev siv tshuaj lom neeg hauv hluav taws xob tam sim no
Cov cim tshuaj thiab cov qauv tshuaj yog dab tsi?
Cov cim tshuaj lom neeg yog ib qho-lossis ob-txoj kev tsim qauv ntawm ib lub caij. Compounds yog kev sib txuas ntawm ob lub ntsiab lus. Cov tshuaj formula yog ib qho kev qhia uas qhia cov ntsiab lus hauv ib qho kev sib txuas thiab cov txheeb ze ntawm cov ntsiab lus. Ntau lub ntsiab lus muaj cov cim uas tau los ntawm Latin lub npe rau lub caij
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
