Yuav ua li cas mus nrhiav tau tawm lub zoo thiab ntau pes tsawg leeg ntawm lub substance

Xav txog cov zoo thiab ntau pes tsawg leeg ntawm tshuaj. Txhais nws tus yam ntxwv rau tebchaw ntawm cov organic thiab inorganic keeb kwm.

Qhov ntawd qhia tau hais tias qhov zoo ntawm cov tshuaj yeeb dej caw

Nws qhia tau hais tias cov kev atoms, uas yog analyzed nyob rau hauv lub molecule. Piv txwv li, dej yog tsim los ntawm hydrogen thiab oxygen.

Molecule sodium oxide muaj xws li sodium thiab cov pa atoms. Lub sulfuric acid uas muaj hydrogen, oxygen, sulfur.

Qhov ntawd qhia tau hais tias muaj pes tsawg leeg ntawm lub quantitative

Nws qha cov quantitative cov ntsiab lus ntawm txhua lub caij tsis pub dhau lub complex substance.

Piv txwv li, dej yog ob hydrogen atoms thiab ib tug ntawm cov pa. Sulfuric acid muaj ob tug hydrogens, ib leej faj atom, plaub oxygens.

Muaj pes tsawg leeg ntawm orthophosphoric acid peb hydrogen atoms, ib tug phosphorus plaub oxygen atoms.

Zoo thiab ntau pes tsawg leeg ntawm tshuaj kuj muaj organic tshuaj. Piv txwv li, methane muaj ib cov thiab plaub hydrogen.

Txoj kev rau kev txiav txim nyob tus yeees ntawm cov tshuaj yeeb dej caw

Zoo thiab ntau pes tsawg leeg ntawm tshuaj yuav tsum tau txiav txim los ntawm tshuaj txhais tau tias. Piv txwv li, decomposition ntawm lub complex compound molecule ob peb molecules tsim nrog ib tug yooj yim qauv. Yog li, thaum lub sij hawm ua cua sov rau hauv lub calcium carbonate muaj calcium uas, carbon, thiab oxygen plaub atoms, nws yog ua tau kom tau ob oxide: calcium thiab cov pa roj carbon.

Complex tshuaj thiab tsim nyob rau hauv lub chav kawm ntawm lub decomposition ntawm cov tshuaj compound tej zaum yuav sib txawv ntawm cov zoo thiab ntau pes tsawg leeg ntawm tshuaj.

Tej yam yooj yim thiab complex tebchaw yuav ua tau molecular thiab uas tsis yog-molecular qauv.

Cov thawj pab pawg neeg yog nyob rau hauv tej lub xeev ntawm aggregation. Piv txwv li, lub qab zib yog ib yam khoom, dej - kua oxygen - roj.

Tebchaw uas tsis yog-molecular qauv ntawm standard tej yam kev mob yog nyob rau hauv cov khoom daim ntawv. Cov no muaj xws ntsev. Thaum lub sij hawm ua cua sov lawv yaj, kis los ntawm ib tug khoom daim ntawv mus rau ib tug kua hauv lub xeev.

Piv txwv ntawm kev txiav txim muaj pes tsawg leeg

"Piav qhia txog qhov zoo thiab ntau pes tsawg leeg cov nram qab no yam: leej faj oxide (4), sulfur oxide (6) '. Cov hauj lwm yog ib tug qauv nyob rau hauv lub tsev kawm ntawv chav kawm ntawm inorganic Science News for KIDS. Yuav kom tiv nrog nws, koj thawj zaug yuav tsum los tsim ib lub mis ntawm lub tebchaw siv valences los yog oxidation lub xeev.

Nyob rau hauv ob qho tib si lub tswv yim oxides tuaj ib yam tshuaj hais, thiaj li, tib zoo pes tsawg leeg. Cov no muaj xws oxygen thiab leej faj atoms. Tab sis nyob rau hauv ib tug kev faib ua feem ntawm cov kev tshwm sim yuav tsum sib txawv.

Tus thawj compound muaj ob oxygen atoms, thiab lub thib ob muaj rau.

Ua raws li nram no ua hauj lwm: "Piav qhia txog qhov zoo thiab ntau pes tsawg leeg ntawm H2S tshuaj."

Lub molecule muaj hydrogen sulphide los ntawm cov leej faj atom thiab ob hydrogens. Zoo thiab ntau pes tsawg leeg ntawm cov ntaub ntawv uas tso cai rau lub H2S twv seb nws tshuaj zog. Txij li thaum hydrogen yog tam sim no nyob rau hauv nyob tus yeees ntawm ib tug ntawv, hydrogen sulfide yuav muaj oxidizing zog. Piv txwv li, uas zoo sib xws yam ntxwv muaj qhia nyob rau hauv nrog ib tug active hlau.

Ntaub ntawv hais txog cov zoo thiab ntau pes tsawg leeg ntawm lub substance yog yam rau organic tebchaw. Piv txwv li, kev paub txog lub ntau cov ntsiab lus ntawm Cheebtsam nyob rau hauv lub hydrocarbon molecule, ib tug yuav txiav txim nws teej tug mus rau ib tug hauv chav kawm ntawv ntawm tshuaj.

Cov ntaub ntawv no tso cai rau koj mus twv seb lub cev thiab tshuaj cov yam ntxwv ntawm lub analyte hydrocarbon qhia nws tej khoom.

Piv txwv li, paub txog tias muaj pes tsawg leeg muaj plaub carbon atoms thiab kaum hydrogens yuav xaus no substance teej tug mus rau cov chav kawm ntawv txwv (nyeem) hydrocarbon muaj cov kev mis SpN2p + 2. Rau tag nrho cov neeg ntawm lub homologous series ntawm cov yam ntxwv hloov cov tshuaj tiv thaiv los ntawm ib tug radical mechanism, raws li zoo raws li huab cua oxidation.

xaus

Tej inorganic thiab organic tshuaj muaj ib tug tej yam zoo thiab ntau pes tsawg leeg. Cov ntaub ntawv tsim nyog los tsim kom muaj lub cev thiab tshuaj thaj chaw ntawm lub analyte inorganic tebchaw thiab organic tebchaw mus rau lub muaj pes tsawg leeg tso cai rau kom muab teej tug mus rau ib chav kawm ntawv paub yam ntxwv thiab tej tshuaj zog.
