Piv txwv li, nrog ceev faj tswj cov pa, lub oxide M2O (qhov M sawv cev rau cov hlau alkali) tuaj yeem tsim tau nrog ib qho ntawm cov hlau alkali. Thaum rhuab, lithium, sodium, potassium, rubidium, thiab cesium ignite los ntawm combustion tshua nrog oxygen.
Yuav ua li cas hlau reacts nrog oxygen rau oxides?
Xeb cov ntaub ntawv ntawm qhov chaw hlau lossis cov khoom hlau, thaum qhov chaw ntawd nkag mus rau hauv cov pa. Cov pa oxygen molecules sib tsoo nrog cov hlau atoms ntawm qhov chaw ntawm cov khoom, thiab lawv hnov mob tsim hlau oxide.
Puas yog hlau oxides tsim thaum hlau hnov mob nrog oxygen?
Metals, thaum raug hlawv hauv huab cua, hnov mob nrog cov pa kom tsim metal oxides.
Cov hlau ua oxides nrog oxygen li cas?
Vim nws cov electronegativity, oxygen cov ntaub ntawv ruaj khov chemical bonds nrog yuav luag txhua lub ntsiab lus los muab cov oxides sib xws. Noble hlau (xws li kub lossis platinum) tau txais txiaj ntsig vim lawv tiv thaiv cov tshuaj lom neeg ncaj qha nrog oxygen, thiab cov khoom xws li kub (III) oxide yuav tsum tau tsim los ntawm kev tsis ncaj ncees.
hom hlau twg ua oxide?
Metals nyiam tsim basic oxides, cov hlau tsis zoo yuav tsim cov kua qaub oxides, thiab amphoteric oxides yog tsim los ntawm cov khoom nyob ze ntawm thaj tsam ntawm cov hlau thiab cov hlau tsis muaj hlau (metalloids).

Thaum carbonic acid reacts nrog potassium feldspar?
Cov tshuaj tiv thaiv ntawm carbonic acid nrog potassium feldspar ua rau feldspar rau chemically decompose. Huab cua ntawm cov poov tshuaj feldspar tsim cov av nplaum, soluble ntsev (potassium bicarbonate), thiab silica hauv kev daws. Thaum feldspar raug tawm tsam los ntawm carbonic acid Nws tsim dab tsi?
Vim li cas hlau tsis tsim nyog raws li cov tub ntxhais ntawm cov hlau nplaum?
Yog cov hlau siv los ua cov tub ntxhais ntawm cov hlau nplaum, cov hlau tsis plam tag nrho nws cov hlau nplaum thaum tam sim no nres thiab nws dhau los ua cov hlau nplaum ruaj khov. Yog li cov hlau tsis siv los ua lub hauv paus ntawm electromagnet.
Yuav ua li cas thaum chlorobenzene reacts nrog naoh?
Chlorobenzene rau Phenol | C 6 H 5 -Cl + NaOH Reaction. Thaum kho chlorobenzene thiab rhuab nrog concentrated NaOH,phenol yog muab ua khoom. Diphenyl ether thiab NaCl kuj yog tsim los ua cov khoom lag luam. Puas chlorobenzene react nrog NaOH?
Thaum acetaldehyde reacts nrog fehling tov?
Nws kuj yog siv los ua qhov ntsuas kom txo qis thiab tsis txo cov suab thaj. Lub precipitate tsim yog xim liab thiab tsuas yog muab thaum Fehling qhov kev sim ua tiav rau aldehyde. Yog li, cov nag lossis daus liab tsim thaum Fehling cov tshuaj reacts nrog aldehyde yog\[
Lub sijhawm txo cov amination ammonium ion reacts nrog?
Hauv kev txo qis, nrog kev pab ntawm glutamate dehydrogenase enzymes, ammonium Ion cuam tshuam nrog the α-ketoglutaric acid rau daim glutamic acid. rau qhov tshuaj tiv thaiv no yuav tsum tau txo coenzyme. Yuav ua li cas txo qis amination?
