Cov pa oxygen yog yaj hauv lub dej , ib yam li ntsev tuaj yeem yaj. Nws ua tsis yog (rau ib qho kev kawm tiav) ua ke nrog dej molecules los tsim hydrogen peroxide . Yog vim li cas oxygenated dej yog tsis yog fizzy zoo li dej qab zib dej (CO2) yog solubility ntawm oxygen hauv dej yog li 2% ntawm CO2.
Yog li ntawd, vim li cas h2o txawv ntawm h2o2?
Dej thiab hydrogen peroxide yog tsim los ntawm tib lub ntsiab: oxygen thiab hydrogen. Txawm li cas los xij, hydrogen peroxide ( H2O2 ) muaj 1 ntau dua oxygen dej ( H2O ). txheej txheem: Dej muaj 2 hydrogens thiab 1 oxygen, thiab hydrogen peroxide muaj 2 hydrogens thiab 2 oxygens.
Tom qab, lo lus nug yog, yog h202 dej? Hydrogen Peroxide . Hydrogen Peroxide (H2O2) yog cov kua tsis muaj xim uas zoo ib yam dej nyob rau hauv ntau yam kev hwm. Nws lub cev muaj zog zoo ib yam li cov dej , tshwj tsis yog tias nws yog 40% denser. Qhov sib txawv tseem ceeb ntawm hydrogen peroxide thiab dej Txawm li cas los xij, nyob rau hauv nws tus cwj pwm chemical.
Kuj Paub, vim li cas h2o2 tsis ruaj khov dua h2o?
Oxygen yog feem ntau ruaj khov nrog tus lej oxidation ntawm -2. Yog li, nws xav kom txo qis (tau txais electrons) mus rau lub xeev oxidation ntawm -2 thiab nyob rau hauv tus txheej txheem nws yuav tsum tau oxidize (txiav tawm electrons) lwm yam kom ua tiav lub hom phiaj no. Yog li, H2O2 yog tus neeg sawv cev oxidizing vim O nyob rau hauv lub xeev tsis ruaj tsis khov oxidation.
Puas yog h2o thiab h2o2 tib qhov sib xyaw?
Tsis yog vim muaj 2 oxygen tsis yog 1 ces lawv txawv tshuaj sib xyaw . ob tug qauv rau tshuaj sib xyaw muaj hydrogen thiab oxygen H2O thiab H2O2.

Qhov laj thawj twg zoo tshaj plaws piav qhia vim li cas cov hlau tsis muaj ductile es tsis nkig?
Cov hlau yog ductile es tsis txhob nkig vim tias lawv muaj cov ntawv cog lus hloov tau. Ductility txhais tau hais tias muaj peev xwm ntawm cov hlau los kos rau hauv cov xov hlau. Cov hlau muaj cov khoom sib txuas yooj yim. Qhov kev hloov pauv no tso cai rau lawv ua cov khoom siv
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Vim li cas lub cube cag ntawm tus lej tsis zoo yog tus lej tsis zoo?
Tus lej tsis zoo lub voos xwmfab hauv paus yuav tsis zoo Txij li qhov ntsuas tus lej txhais tau tias tsa nws mus rau lub zog thib 3 - uas yog khib - lub voos xwmfab ntawm cov lej tsis zoo yuav tsum yog qhov tsis zoo. Thaum lub qhov hluav taws xob tawm (xiav), qhov tshwm sim tsis zoo. Thaum lub qhov hluav taws xob qhib (daj), qhov tshwm sim yog qhov zoo
Vim li cas koj tig lub cim tsis sib xws thaum koj sib npaug lossis faib los ntawm qhov tsis zoo?
Thaum koj muab ob sab los ntawm tus nqi tsis zoo koj ua rau sab uas ntau dua muaj 'loj' tus lej tsis zoo, uas txhais tau tias tam sim no tsawg dua lwm sab! Qhov no yog vim li cas koj yuav tsum tig lub cim thaum twg koj muab los ntawm tus lej tsis zoo
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
