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.
Vim li cas cov ntawv sau npe siv hauv cov qauv tshuaj?
Peb siv cov ntawv sau npe hauv cov qauv tshuaj rau qhia cov lej ntawm cov atoms ntawm ib lub caij tam sim no hauv am molecule lossis formula unit… oxygen. Hais txog cov atoms, dej ib txwm muaj 2: 1 piv ntawm hydrogen rau oxygen.
Tus subscript txhais li cas hauv kev sib npaug tshuaj?
Subscripts yog cov lej tom qab lub cim thiab hauv qab no. Subscripts qhia koj tus lej ntawm atoms ntawm lub caij ntawd Yog tias lub ntsiab tsis muaj subscript, ces nws nkag siab tias tus lej yog 1. Li2Cl3 muaj ob lub lithium atoms thiab peb chlorine atoms.
Lub hom phiaj ntawm cov ntawv sau thiab cov coefficients hauv cov qauv tshuaj yog dab tsi?
Tus coefficient qhia koj tias pes tsawg molecules ntawm cov khoom ntawd muaj. Lub subscript qhia koj tias nws yog dab tsi. Nws qhia koj tus nqi ntawm txhua lub ntsiab lus muaj nyob hauv molecule. Hloov nws yuav hloov cov khoom nws tus kheej.
Subscript nyob rau hauv cov tshuaj mis nyob qhov twg?
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 nyob.
