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.
