Pawg 15: Cov Nitrogen Tsev Neeg . Cov tsev neeg nitrogen suav nrog cov tshuaj hauv qab no: nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), thiab bismuth (Bi). AllGroup 15 cov ntsiab lus muaj cov khoom siv hluav taws xob2np3 nyob rau hauv lawv lub plhaub sab nrauv, qhov twg n yog tus lej quantum.
Kuj paub yog, dab tsi yog tsev neeg lossis pab pawg ntawm nitrogen?
Qhov no pab pawg tseem hu ua tsev neeg nitrogen . Nws muaj cov ntsiab lus nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), thiab tej zaum cov tshuaj tsis muaj tshuaj lom neeg cov khoom siv moscovium (Mc). Nyob rau hauv niaj hnub IUPAC cim, nws yog hu ua Pab pawg 15.
Ib sab saum toj no, lub hauv paus ntsiab lus ntawm nitrogen yog dab tsi? Nitrogen tau tshawb pom los ntawm Daniel Rutherford (GB) hauv 1772. Lub keeb kwm ntawm npe los ntawm Greekwords nitron noob lub ntsiab lus nitre thiab sib sau thiab Latin lus nitrum (nitre yog ib hom npe rau potassiumnitrate, KNO3). Nws yog xim tsis muaj xim, tsis muaj ntxhiab, feem ntau inert gas, minimally reactive nyob rau hauv chav tsev kub.
Tsuas yog li ntawd, yog vim li cas nitrogen nyob rau hauv pab pawg 15?
Pawg 15 (VA) muaj nitrogen , phosphorous, arsenic, antimony, thiab bismuth. Cov ntsiab lus hauv Pawg 15 muaj tsib valence electrons. Vim hais tias cov ntsiab lus tuaj yeem tau txais peb lub tshuab hluav taws xob lossis poob tsib kom tau txais kev teeb tsa ruaj khov, lawv feem ntau tsim covalent tebchaw tshwj tsis yog kev sib koom ua ke rau ib qho activemetal.
Leej twg nrhiav tau lub tsev neeg nitrogen?
Keeb kwm thiab kev siv: Nitrogen yog nrhiav pom los ntawm tus kws kho mob Scottish Daniel Rutherford hauv xyoo 1772. Nws yog qhov thib tsib tshaj plaws hauv ntiaj teb thiab tsim txog li 78% ntawm lub ntiaj teb satmosphere, uas muaj kwv yees li 4,000 trillion tons ntawm thegas.

Dab tsi yog qhov tseem ceeb tshaj plaws hauv tsev neeg ntawm kev ua haujlwm?
Niam txiv txoj haujlwm yog qhov tseem ceeb tshaj plaws hauv ib tsev neeg ntawm kev ua haujlwm los ntawm tag nrho lwm yam haujlwm hauv tsev neeg tuaj yeem muab tau. Qee qhov piv txwv ntawm cov tsev neeg ntawm cov dej num muaj xws li quadratic functions, linear functions, exponential functions, logarithmic functions, radical functions, los yog rational functions
Dab tsi yog cov ntsiab lus hauv tsev neeg nitrogen?
Nitrogen tsev neeg muaj tsib lub ntsiab lus, uas pib nrog nitrogen ntawm lub sij hawm lub rooj thiab txav mus rau hauv pawg los yog kem: nitrogen. phosphorus. arsenic. antimony. bismuth
Ib qho piv txwv ntawm tsev neeg gene yog dab tsi?
Gene tsev neeg: Ib pawg ntawm cov noob uas muaj feem xyuam nrog cov qauv thiab feem ntau ua haujlwm. Cov noob nyob rau hauv ib tsev neeg gene yog nqis los ntawm cov noob caj noob ces. Piv txwv li, cov noob hemoglobin muaj nyob hauv ib tsev neeg cov noob uas tau tsim los ntawm cov noob duplication thiab sib txawv
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
Cov piv txwv ntawm tsev neeg cov kua qaub thiab cov hauv paus yog dab tsi?
Daim ntawv teev cov tsev Bases & Acids Baking Soda. Baking soda yog lub npe nrov rau sodium bicarbonate, paub tshuaj raws li NaHCO3. Diluted Soaps. Tsev neeg Ammonia. Tsev Neeg Vinegar. Citric Acid
