Pure Substance: Cov tshuaj uas tsis muaj kev sib xyaw ua ke thiab tsuas muaj ib hom particle xwb yog cov tshuaj dawb huv. Piv txwv ntawm cov khoom ntshiab muaj xws li hlau, txhuas, nyiaj , thiab kub.
Yog li, puas yog txhuas yog cov khoom ntshiab?
e) Aluminium yog chemical element ces nws yog a cov khoom ntshiab.
Tsis tas li ntawd, yam khoom dab tsi yog aluminium? Aluminium . Aluminium (Al), kuj sau aluminium , tshuaj keeb , ib lub teeb yuag, silvery-dawb hlau ntawm lub ntsiab pawg 13 (IIIa, los yog boron pawg) ntawm lub sij hawm.
Ib sab saum toj no, qhov twg yog cov khoom ntshiab?
A cov khoom ntshiab los yog tshuaj yam khoom yog ib yam khoom uas muaj ib tug tas li muaj pes tsawg leeg (yog homogeneous) thiab muaj cov khoom zoo ib yam thoob plaws hauv cov qauv. Hauv chemistry, a cov khoom ntshiab tsuas muaj ib hom atom, molecule, los yog compound. Hauv lwm cov kev qhuab qhia, lub ntsiab lus txuas mus rau homogeneous sib tov.
Puas yog huab cua ntshiab huv?
Teb thiab piav qhia: Cua tsis yog a cov khoom ntshiab vim nws yog homogeneous sib tov sib txawv tshuaj . Cua yog homogeneous sib tov vim huab cua yog ib tug kom huv si
Pom zoo:
Dab tsi yog qhov me me ntawm cov khoom uas khaws cov khoom ntawm lub caij?
Ib qho atom yog qhov tsawg tshaj plaws ntawm txhua lub caij uas tseem khaws cov yam ntxwv ntawm lub caij ntawd. Ib daim ntawm ib lub caij uas peb tuaj yeem pom lossis kov yog ua los ntawm ntau, ntau atoms thiab tag nrho cov atoms yog tib yam lawv txhua tus muaj tib tus naj npawb ntawm protons
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Puas yog cov pa roj carbon dioxide yog cov khoom ntshiab?
Yog, carbon dioxide yog cov khoom ntshiab tsis yog sib tov. Piv txwv ntawm cov khoom ntshiab muaj xws li hlau, nyiaj, mercury thiab lwm yam. Thiab cov tebchaw xws li dej, carbon dioxide, methane, vinegar
Dab tsi yog cov khoom ntawm phosphorous acid Dab tsi yog nws cov mis?
Phosphorous acid (H3PO3) tsim cov ntsev hu ua phosphites, kuj siv los txo cov neeg ua haujlwm. Nws yog npaj los ntawm dissolving tetraphosphorus hexoxide (P4O6) los yog phosphorus trichloride (PCl3) hauv dej
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
