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?
Ib tus qauv molecular yog tus sawv cev ntawm cov molecule uas siv cov cim tshuaj los qhia cov hom atoms ua raws li cov ntawv sau npe qhia cov naj npawb ntawm atoms ntawm txhua hom hauv cov molecule(Ib tug subscript tsuas yog siv thaum muaj ntau tshaj ib tug atom ntawm ib hom muab.)
Qhov twg yuav tsum sau cov ntawv sau rau hauv kev sib npaug tshuaj?
Notation for a Chemical Equation
Lub xeev ntawm teeb meem ntawm txhua qhov sib xyaw lossis molecule yog qhia nyob rau hauv subscript tom ntej ntawm cov compound los ntawm cov ntawv luv hauv kab lus Piv txwv li, ib tug compound nyob rau hauv lub gas xeev yuav qhia los ntawm (g), khoom (s), kua (l), thiab aqueous (aq).
Dab tsi yog subscript thiab nws siv li cas hauv chemistry?
A subscript is a cim, feem ntau yog ib tsab ntawv lossis tus lej, uas tau luam tawm me ntsis hauv qab thiab rau sab ntawm lwm tus cimCov ntawv sau feem ntau yog siv rau hauv cov qauv tshuaj. Ib tug kws tshawb fawb yuav sau cov mis rau dej, H2O, kom lub 2 tshwm qis dua thiab me dua cov ntawv ntawm ob sab ntawm nws.
2 lub hom phiaj ntawm kev sau npe yog dab tsi?
Cov qauv tshuaj siv cov tsiaj ntawv thiab cov lej los sawv cev rau hom tshuaj (piv txwv li, cov tebchaw, ions). Cov lej tshwm sim raws li cov ntawv sau npe hauv cov qauv tshuaj qhia tias tus lej ntawm atoms ntawm lub caij tam sim ua ntej subscript. Yog tias tsis muaj subscript tshwm sim, ib qho atom ntawm lub ntsiab yog tam sim no.

Kev nyeem ntawv thiab qauv dab tsi tshwm sim thaum sau tsab ntawv?
Readability yog ntsuas qhov yooj yim npaum li cas ntawm cov ntawv nyeem yog nyeemNws tuaj yeem suav nrog cov ntsiab lus ntawm kev nyuaj, kev paub, kev paub, thiab kev sau ntawv. Cov qauv kev nyeem ntawv feem ntau saib cov yam xws li kab lus ntev, lub suab nrawm thiab cov lus paub zoo raws li ib feem ntawm lawv cov kev suav .
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 .
Cov ntawv sau npe nyob qhov twg hauv cov qauv tshuaj?
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 .
Puas yog cov ntawv sau thiab cov ntawv sau?
Cov ntawv sau yog ib tug sau los yog ib tug manually typewritten document, whereas inscription is the writes on the hard surfaces such as pob zeb los yog hlau . Cov ntawv sau thiab cov ntawv sau npe yog dab tsi? Ans.: Cov ntawv sau yog sau los ntawm tes uas feem ntau tau sau rau ntawm nplooj xibtes, lossis ntawm cov ntoo npaj tshwj xeeb ntawm tsob ntoo thaum cov ntawv sau tau kos rau ntawm cov tawv tawv xws li pob zeb thiab hlau .
Vim li cas cov ntawv sau npe hauv cov qauv tshuaj?
Cov qauv tshuaj siv cov tsiaj ntawv thiab cov lej los sawv cev rau hom tshuaj (piv txwv li, cov tebchaw, ions). … Cov lej tshwm sim raws li cov ntawv sau npe hauv cov tshuaj formula qhia cov lej ntawm cov atoms ntawm lub caij tam sim ua ntej subscriptYog tias tsis muaj cov ntawv sau tshwm, ib lub atom ntawm lub ntsiab lus tam sim no .
