Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug CaO + H2O = Ca(OH)2 thiab muab cov coefficients raug rau txhua qhov sib xyaw. Ua kom sib npaug CaO + H2O = Ca(OH)2 koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug.
Kuj nug, dab tsi yog cov khoom ntawm calcium oxide thiab dej?
Thaum twg calcium oxide (chemical formula: CaO ) reacts nrog dej (cov tshuaj formula: H2O), cov tshuaj tiv thaiv hauv qab no tshwm sim: Cov khoom ntawm no cov tshuaj tiv thaiv yog calcium hydroxide , tseem hu ua slaked txiv qaub. Yog li ntawd, thaum calcium oxide reacts nrog dej , slaked txiv qaub yog tsim.
Kuj Paub, hom tshuaj tiv thaiv yog CaO h2o caoh2? Cov tshuaj tiv thaiv ntawm calcium oxide (CaO) thiab dej (H2O) tsim calcium hydroxide Ca(OH)2 yog ib qho exothermic ua ke tshuaj tiv thaiv. Cov tshuaj tiv thaiv no ua rau muaj cua sov ntau nrog rau lub suab nrov thiab yog li tau hais tias yog exothermic.
Xav txog qhov no, yuav ua li cas thaum CaO ntxiv rau dej?
Thaum twg dej yog ntxiv mus rau calcium oxide (quicklime), nws yuav hloov mus rau calcium hydroxide (slaked txiv qaub) nrog rau kev ywj pheej ntawm cov cua sov loj heev. Nws yog ib qho tshuaj tiv thaiv exothermic. Calcium hydroxide yog alkali.
Qhov sib npaug ntawm CaO h2o Ca OH 2 h2 yog dab tsi?
Chemical Equation Balancer Ca + H2O = Ca ( OH ) 2 + H2.

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
