Thaum twg npe molecular compounds prefixes yog siv los txiav txim tus naj npawb ntawm cov khoom muab tam sim no hauv cov compound. "mono-" qhia ib, "di-" qhia ob, "tri-" yog peb, "tetra-" yog plaub, "penta-" yog tsib, thiab "hexa-" yog rau, "hepta-" yog xya, "octo-" yog yim, "nona-" yog cuaj, thiab "deca" yog kaum.
Ib yam li ntawd, koj ua li cas lub npe atoms?
Thawj lo lus yog tus npe ntawm thawj lub ntsiab. Lo lus thib ob qhia koj lub ntsiab lus thib ob thiab pes tsawg atoms muaj nyob rau hauv lub compound. Lo lus thib ob feem ntau xaus rau hauv IDE. Qhov ntawd yog lub ntsiab lus.
Ib sab saum toj, yog vim li cas oxygen yog diatomic molecule? Oxygen feem ntau muaj raws li ib tug Diatom molecule nyob rau hauv cov huab cua thaum nws tsis ua ke nrog lwm yam. Nws forms molecule ua O2 vim hais tias nyob rau hauv lub configuration, nws muaj nws qis zog theem thaum uncombined. Txhua yam khoom zoo li mus rau qib qis tshaj plaws uas ua tau. Oxygen muaj 6 valence electrons.
Ib yam li ntawd, tib neeg nug, ua li cas koj lub npe tshuaj formulas thiab compounds?
Thawj lub hauv paus qauv tsuas yog sau npe siv cov npe ntawm lub ntsiab. Lub caij thib ob yog lub npe los ntawm kev noj cov qia ntawm lub caij npe thiab ntxiv cov suffix -ide. Ib tug txheej txheem ntawm cov zauv prefixes yog siv los qhia cov naj npawb ntawm atoms nyob rau hauv ib lub molecule.
Puas yog molecule?
Cov pa roj carbon monoxide molecule . Cov pa roj carbon monoxide yog ib qho tsis muaj xim, tsis muaj ntxhiab, tsis muaj roj. A molecule ntawm carbon monoxide ( CO ) muaj ib tug carbon atom thiab ib tug oxygen atom.

Vim li cas peb thiaj li kho cov coefficients thaum ntsuas cov tshuaj sib npaug thiab tsis yog cov ntawv sau npe?
Thaum koj hloov cov coefficients, koj tsuas yog hloov tus naj npawb ntawm cov molecules ntawm cov khoom tshwj xeeb. Txawm li cas los xij, thaum koj hloov cov ntawv sau npe, koj tab tom hloov cov tshuaj nws tus kheej, uas yuav ua rau koj qhov sib npaug tshuaj tsis raug
Lub npe rau ib yam khoom tsim nyob rau hauv cov tshuaj tiv thaiv tshuaj yog dab tsi?
Cov tshuaj tiv thaiv tshuaj yog cov txheej txheem uas cov atoms tam sim no nyob rau hauv cov tshuaj pib rov ua kom muab cov tshuaj sib xyaw tshiab tam sim no hauv cov tshuaj tsim los ntawm cov tshuaj tiv thaiv. Cov tshuaj pib ntawm cov tshuaj tiv thaiv tshuaj hu ua reactants, thiab cov tshuaj tshiab uas tshwm sim hu ua cov khoom
Yuav ua li cas koj yuav tsum siv ib daim ntawv qhia txog lub npe tshuaj compound?
Yuav ua li cas koj yuav tsum siv ib daim ntawv qhia txog lub npe tshuaj compound? Txhawm rau sau npe los yog sau nws cov qauv, ua raws cov kab kos hauv cov duab 9.20 thiab 9.22 rau lub npe tiag tiag lossis qauv
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
Koj sau cov npe tshuaj thiab cov qauv li cas?
Thaum sau cov mis, qhov zoo atom lossis ion los ua ntej los ntawm lub npe ntawm qhov tsis zoo ion. Lub npe tshuaj 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
