Al2O3
Tsis tas li ntawd, Al o2 yog dab tsi?
Ib qho kev sib npaug ntawm cov tshuaj qhia tau hais tias cov tshuaj tiv thaiv (cov reactants) ua raws li cov xub ua raws li cov tshuaj uas tsim los ntawm cov tshuaj tiv thaiv (cov khoom). Peb yuav muab qhov sib npaug: Al + O2 Al2O3.
Dab tsi yog cov khoom ntawm Al2O3? Aluminium oxide
Yog li ntawd, yuav ua li cas thaum Aluminium reacts nrog oxygen?
Kev tshwm sim ntawm aluminium nrog huab cua Qhov saum npoo ntawm aluminium hlau yog them nrog ib txheej nyias ntawm oxide uas pab tiv thaiv cov hlau los ntawm kev tawm tsam los ntawm huab cua. Aluminium yuav hlawv hauv oxygen nrog cov nplaim dawb ci ntsa iab los tsim cov trioxide alumnium (III) oxide, Al2O3.
Cov mis rau txhuas thiab oxygen yog dab tsi?
Aluminium oxide (IUPAC lub npe) los yog aluminium oxide (American English) yog ib qho tshuaj sib xyaw ntawm txhuas thiab oxygen nrog cov tshuaj formula Al2O3. Nws yog qhov tshwm sim feem ntau ntawm ob peb aluminium oxides , thiab tshwj xeeb yog aluminium (III) oxide.

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%
Dab tsi yog qhov zoo sib xws ntawm cov khoom thiab cov khoom sib txuas?
Cov ntsiab lus thiab cov tebchaw yog cov tshuaj homogeneous nkaus xwb thiab lawv muaj qhov sib xyaw tas li thoob plaws. Cov ntsiab lus thiab cov tebchaw tsis tuaj yeem sib cais rau hauv lawv cov khoom sib xws los ntawm kev siv lub cev. Cov tshuaj thiab cov khoom sib tov yog tsim los ntawm cov khoom sib txawv lossis cov atom sib txawv
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
