Rau atoms uas muaj ob lossis ntau dua ntawm ib hom atom tam sim no, ib qho kev sau npe yog sau tom qab lub cim rau lub atom ntawdPolyatomic ions hauv cov qauv tshuaj muaj nyob rau hauv kab lus ua raws los ntawm subscript yog tias muaj ntau tshaj ib yam ntawm tib hom polyatomic ion muaj.
Yuav ua li cas yog subscript hauv cov tshuaj formula?
Tshuaj xyuas: Cov qauv tshuaj yog siv los piav txog hom atoms thiab lawv cov lej hauv cov molecule lossis cov khoom sib xyaw. Lub atoms ntawm txhua lub caij yog sawv cev los ntawm ib lossis ob tsab ntawv sib txawv. Thaum ntau tshaj ib lub atom ntawm ib lub ntsiab lus pom nyob rau hauv ib lub molecule, ib tug subscript yog siv los qhia qhov no nyob rau hauv cov tshuaj formula.
Subscripts nyob qhov twg?
A subscript lossis superscript yog tus cim (xws li tus lej lossis tsab ntawv) uas tau teeb tsa me ntsis hauv qab lossis siab dua kab ntawm hom ib txwm, raws li. Nws feem ntau yog me dua li ntawm cov ntawv nyeem. Subscripts tshwm ntawm lossis hauv qab kab ntawv, thaum cov ntawv sau saum toj no.
subscripts qhia koj li cas?
A subscript qhia rau koj pes tsawg atoms ntawm txhua lub ntsiab muaj nyob rau hauv ib tug compound los yog molecule.
piv txwv subscript yog dab tsi?
Subscript yog cov ntawv uas ib tsab ntawv me me / tus lej sau tom qab ntawv tshwj xeeb / tus lej. Nws dai hauv qab nws tsab ntawv lossis tus lej. Nws yog siv thaum sau cov tshuaj sib xyaw. Ib qho piv txwv ntawm subscript yog N2.

Cov qauv thiab cov qauv rau cov kws qhia ntawv yog dab tsi?
Cov Qauv thiab Cov Qauv rau Cov Kws Qhia Ntawv (NSE) siv ib qho txiaj ntsig raws li txoj hauv kev rau cov kws qhia ntawvthiab muab cov lus piav qhia ntxaws txog qhov uas tus kws qhia ntawv muaj peev xwm ua tau. Qhov tseem ceeb ntawm txoj cai yog kev ua tau zoo hauv cov tsev kawm ntawv, chav kawm, kev tswj hwm thiab kev txhawb nqa ntawm lub tsev kawm ntawv .
Thaum twg thiab qhov twg siv cov ntawv sau npe thaum sau cov qauv tshuaj?
Ib qho 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. Yog tias tsuas yog ib qho atom ntawm ib hom tshwj xeeb yog tam sim no, tsis muaj subscript siv. Rau atoms uas muaj ob lossis ntau dua ntawm ib hom tshwj xeeb ntawm atom tam sim no, ib daim ntawv sau npe sau tom qab lub cim rau lub atom Dab tsi yog cov ntawv sau npe siv rau hauv cov qauv tshuaj?
Qhov twg yog cov lus qhia nyob rau hauv kab ntawv sau npe?
Cov lus sau hauv ntawv yuav tsum tshwm sim hauv kab lus uas cov khoom siv tau raug siv: Signal kab lus siv (tus sau lub npe) tshwm nyob rau hauv kab lus nrog nplooj ntawv tus lej hauv kab lus tom kawg ntawm kab lus. Cov ntaub ntawv qhia tag nrho (tus sau lub xeem thiab tus lej nplooj ntawv) tshwm rau tom kawg ntawm kab lus.
