Ib oxyanion ua , los yog oxoanion, yog ib qho ion nrog cov qauv A. xO z− y (qhov twg A sawv cev rau a tshuaj lub ntsiab thiab O sawv cev rau ib qho oxygen atom). Oxyanions yog tsim los ntawm ib tug loj feem ntau ntawm cov tshuaj cov ntsiab lus.
Ua kom pom qhov no, oxyanion yog dab tsi muab ob qho piv txwv?
Piv txwv Oxyanion Nitrate (NO3-), Nitrite (NO 2 -), sulfite (SO3 2 -thiab hypochlorite (ClO-) yog tag nrho oxyanions.
Tsis tas li ntawd, lub npe ntawm pb4+ yog dab tsi? Piv txwv li, Fe2+ yog hu ua ferrous ion, thiab Fe3 + yog hu ua ferric ion; Cu + yog cuprous ion, thiab Cu2 + yog cupric ion.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog oxyanion thiab nws lub npe li cas?
Qee lub ntsiab lus tuaj yeem tsim ntau dua ib qho oxyanion ua (polyatomic ions uas muaj cov pa oxygen), txhua tus muaj cov lej sib txawv ntawm cov pa oxygen. Lub anion nrog ib qho ntxiv oxygen atom tshaj li (hauv paus) noj anion yog npe los ntawm kev muab per- thaum pib ntawm lub hauv paus thiab - noj thaum kawg.
Oxoacids txhais li cas?
Ib oxoacid ua yog ib qho acid uas muaj oxygen. Yuav kom paub meej ntxiv, nws yog cov kua qaub uas: 1. muaj cov pa oxygen 2. muaj tsawg kawg yog ib qho lwm yam 3. muaj tsawg kawg yog ib qho hydrogen atom khi rau oxygen 4.

Dab tsi yog PV hauv Chemistry?
Robert Boyle pom PV = qhov tsis tu ncua. Ntawd yog, cov khoom ntawm lub siab ntawm cov roj lub sij hawm lub ntim ntawm cov pa roj yog acconstant rau ib qho piv txwv ntawm cov roj. Hauv Boyle qhov kev sim ntsuas kub (T) tsis hloov, thiab tsis muaj pes tsawg tus moles (n) ofgas tam sim no
Dab tsi yog qhov txawv ntawm cov chemistry thiab organic chemistry?
Organic chemistry yog suav tias yog ib qho kev qhia ntawm chemistry. Thaum lub sij hawm lub kaus dav dav 'chemistry' yog kev txhawj xeeb nrog kev sib xyaw thiab kev hloov pauv ntawm txhua yam teeb meem, cov khoom siv tshuaj lom neeg tsuas yog txwv rau kev kawm ntawm cov organic tebchaw xwb
John Dalton qhov kev ua tiav tseem ceeb hauv chemistry yog dab tsi?
John Dalton FRS (/ˈd?ːlt?n/; 6 Cuaj hlis 1766 – 27 Lub Xya hli ntuj 1844) yog ib tug Askiv chemist, physicist, thiab meteorologist. Nws paub zoo tshaj plaws rau kev qhia txog atomic txoj kev xav rau hauv chemistry, thiab rau nws txoj kev tshawb fawb rau hauv qhov muag tsis pom xim, qee zaum hu ua Daltonism hauv nws txoj kev hwm
Hooke's Law hauv chemistry yog dab tsi?
CHEMISTRY GLOSSARY Hooke txoj cai hais tias lub cev deformation yog proportional rau qhov loj ntawm deforming quab yuam, muab hais tias lub cev elasticity (saib elasticity) tsis tshaj. Yog tias qhov txwv tsis pub ncav cuag, lub cev yuav rov qab mus rau nws qhov qub qub thaum lub zog raug tshem tawm
Dab tsi yog txoj cai cais tawm hauv chemistry?
