a. Thaum twg? dilute sulfuric acid ntxiv mus rau ib tug sib tov ntawm hlau filling thiab sulfur hmoov, tshuaj tiv thaiv occusrs ntawm dilute sulfuric acid thiab hlau Cov ntaub ntawv uas tsim ferrous sulphate thiab evolution ntawm hydrogen. FeS tsim reacts nrog sulfuric acid tsim ferrous sulphate thiab tso tawm hydrogendisulphide roj.
Kuj tseem paub yog, yuav ua li cas thaum hlau sulphide reacts nrog sulfuric acid?
Thaum twg hlau sulfide yog ntxiv rau dilute sulfuric acid , koj yuav tau hlau sulfate, dej thiab sulfur dioxide raws li cov khoom.
Kuj Paub, cov roj twg yog hloov zuj zus thaum hlau sulfide kho nrog dilute sulfuric acid? hydrogen sulfide gas
Qhov thib ob, yuav ua li cas thaum hlau ntxiv rau dilute sulfuric acid?
Cov tshuaj tiv thaiv ntawm hlau nrog acids Hlau hlau dissolves nkag rau hauv dilute sulfuric acid Thaum tsis muaj oxygen los tsim cov kev daws teeb meem uas muaj cov dej Fe (II) ion ua ke nrog hydrogen gas, H2. Yog tias muaj cov pa oxygen, qee qhov Fe (II) oxidizes rau Fe (III).
Yuav ua li cas tshwm sim thaum sib tov ntawm hlau thiab sulfur yog rhuab?
Thaum twg hlau thiab sulfur yog cua sov ib qho tshuaj tiv thaiv yuav tshwm sim I.e. Sulfur ua ke nrog cov hlau hauv sib tov nyob rau hauv lub xub ntiag ntawm kub ua form Hlau sulfide (FeS).

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Yuav ua li cas thaum hlau sulfide reacts nrog sulfuric acid?
Thaum cov hlau sulfide ntxiv rau dilute sulfuric acid, koj yuav tau txais hlau sulfate, dej thiab sulfur dioxide raws li cov khoom
Cov roj twg yog hloov zuj zus thaum hlau sulfide kho nrog dilute sulfuric acid?
Thaum hlau sulfide reacts nrog diluted sulfuric acid, hydrogen sulfide yog tsim uas yog sau nyob rau hauv lub hub gas los ntawm upward tsiv ntawm huab cua
Yuav ua li cas tshwm sim thaum dilute sulfuric acid yog nchuav rau ntawm zinc phaj?
Thaum dilute Sulfuric acid yog nchuav rau ntawm ib lub zincplate, Zinc Sulphate yog tsim nrog Hydrogen gas.Peb tuaj yeem kuaj cov roj hydrogen los ntawm kev noj cov khoom siv hluav taws xob ze ze, thiab cov roj yuav ignite nrog lub suab nrov
Yuav ua li cas tshwm sim thaum koj ntxiv ib tug qaug zog acid rau dej?
Thaum cov kua qaub uas tsis muaj zog ntxiv rau hauv dej, cov ntaub ntawv sib npaug sib npaug hauv cov kua qaub molecules, HA (aq), hnov mob nrog cov dej ua kua los tsim cov aqueous hydronium ions thiab aqueous anions, A-(aq). Cov tom kawg yog tsim thaum cov kua qaub molecules poob H + ions rau dej
