Thaum twg sau qauv , qhov zoo atom los yog ion los ua ntej los ntawm lub npe ntawm qhov tsis zoo ion. Cov tshuaj Lub npe rau cov lus ntsev yog sodium chloride. Lub sij hawm lub sij hawm qhia tau hais tias lub cim rau sodium yog Na thiab lub cim rau chlorine yog Cl. Cov tshuaj formula rau sodium chloride yog NaCl.
Tsis tas li ntawd, cov qauv tshuaj muaj pes tsawg leeg yog dab tsi?
Cov npe ntawm qee yam tshuaj lom neeg
| Lub Npe | Tshuaj npe | Tshuaj Formula |
|---|---|---|
| Blue Vitriol | Tooj sulfate pentahydrate | CuSO4.5 H2O |
| Borax | Sodium tetraborate decahydrate | Na2B4O7.10 H2O |
| Calomel | Cov tshuaj mercurous chloride | HgCl |
| Carbolic acid | Phenol | C6H5OH |
Ib sab saum toj no, cov cai ntawm kev sau cov tshuaj formula yog dab tsi? Peb txoj cai los sau cov qauv tshuaj
- Txheeb xyuas cov cation thiab anion tam sim no hauv cov tshuaj uas yuav tsum tau sau cov mis. Sau cov ions nrog lawv cov nqi them.
- Sib npaug cov nqi los ntawm criss-cross multiplication xws li cation tau txais tus nqi ntawm anion thiab vice-versa.
- Sau cov cation ua ntej ua raws li cov anions.
Ib yam li ntawd, nws yog nug, dab tsi yog ib qho piv txwv ntawm chemical formula?
A tshuaj formula los yog kev sib npaug qhia cov cim ntawm cov ntsiab lus hauv qhov sib xyaw thiab qhov piv ntawm cov ntsiab lus rau ib leeg. Rau piv txwv , cov tshuaj formula rau dej yog H2O uas qhia tias 2 atoms ntawm Hydrogen ua ke nrog 1 atom ntawm oxygen.
Qhov formula ntawm ib qho compound yog dab tsi?
Ib qho tshuaj qauv qhia peb tus lej ntawm atoms ntawm txhua lub ntsiab lus hauv a compound . Nws muaj cov cim ntawm cov atoms ntawm lub ntsiab tam sim no nyob rau hauv lub compound nrog rau ntau npaum li cas muaj rau txhua lub ntsiab lus hauv daim ntawv ntawm subscripts.
