Muaj kwv yees li 10 txawv allotropic daim ntawv ntawm phosphorus . Cov peb feem ntau daim ntawv suav nrog dawb, liab, thiab dub phosphorus . Lub cev muaj zog yog heev txawv los ntawm ib leeg.
Ib yam li ntawd, tib neeg nug, dab tsi yog phosphorus pom nyob rau hauv?
Phosphorus tsis yog pom hauv nws ntshiab elemental daim ntawv ntawm lub ntiaj teb, tab sis nws yog pom hauv ntau cov zaub mov hu ua phosphates. Kev lag luam feem ntau phosphorus yog tsim los ntawm mining thiab cua sov calcium phosphate. Phosphorus yog lub thib kaum ib feem ntau tshaj nyob rau hauv lub ntiaj teb lub crust.
Tsis tas li ntawd, lub xeev ntawm phosphorus yog dab tsi? Phosphorus yog ib yam tshuaj muaj cim P thiab atomic naj npawb 15. Classified as nonmetal, Phosphorus yog ib qho khoom ntawm chav tsev kub.
Ua li no, ob hom allotropic ntawm phosphorus yog dab tsi?
Phosphorus muaj nyob rau hauv ntau hom (allotropes) uas nthuav tawm cov khoom sib txawv
- Ob qho allotropes feem ntau yog dawb phosphorus thiab liab phosphorus.
- Lwm daim ntawv, scarlet phosphorus, yog tau los ntawm kev tso cai rau kev daws ntawm phosphorus dawb hauv carbon disulfide kom evaporate nyob rau hauv tshav ntuj.
Dab tsi yog qhov txawv ntawm liab phosphorus thiab dawb phosphorus?
Dawb phosphorus muaj P4 molecules, whereas tus qauv siv lead ua liab phosphorus muaj ib tug nyuaj network ntawm kev sib raug zoo. Dawb phosphorus yuav tsum tau muab khaws cia rau hauv dej kom tsis txhob muaj kev sib tsoo, tab sis liab phosphorus yog ruaj khov nyob rau hauv huab cua. Daim duab 2: Plaub hom allotropes ntawm phosphorus.

Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?

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
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
