Kuaj Qauv
Cov AP Chemistry Exam muaj ob ntu. Hauv Tshooj I, koj muaj 90 feeb los teb 60 cov lus nug ntau yam uas muaj plaub qhov lus teb xaiv. Seeb II of the kev xeem muaj xya cov lus teb dawb (peb qhov ntev thiab plaub luv luv) uas muaj nqis 50 feem pua ntawm koj cov qhab nia.
Ua li no, pes tsawg feem pua yog 5 ntawm kev xeem AP chemistry?
10%
Ib sab saum toj no, puas yog organic chemistry ntawm AP chemistry test? Tsis muaj direct organic chemistry cov lus nug ntawm AP Chemistry Exam . Tab sis tsis tas yuav tsom mus rau nomenclature lossis tshwj xeeb txog organic chemistry . Tag nrho cov lus nug txog organic Cov tebchaw tuaj yeem teb tau los ntawm kev sib txuas lus, kev sib txuas lus, lossis lwm yam ntsiab lus hauv cov ntaub ntawv kawm.
Tsis tas li ntawd, AP chemistry xeem nyuaj?
Feem ntau cov chav kawm science muaj lub koob npe nrov rau kev ua nyuaj , thiab AP ® Chemistry yog tsis muaj kev zam. Qhov tseeb yooj yim yog qhov ntawd AP ® Chemistry yog a nyuaj chav kawm, tab sis yog tias koj paub tias koj tau txais koj tus kheej li cas thiab npaj raws li, nws muaj peev xwm dhau qhov AP ® Chemistry xeem nrog tus qhab nia siab.
Dab tsi yog chav kawm AP nyuaj tshaj plaws?
Tebchaws Asmeskas Keeb Kwm, Biology, Lus Askiv, Calculus BC, Physics C, thiab Chemistry feem ntau hu ua cov chav kawm nyuaj tshaj plaws AP thiab xeem.

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
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
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
