Thaum twg dilute sulfuric acid yog poured ntawm a zincplate , Zinc Sulphate yog tsim nrog rau cov roj hydrogen. Peb tuaj yeem kuaj cov roj hydrogen los ntawm kev noj cov khoom siv hluav taws xob nyob ze, thiab cov roj yuav ignite nrog lub suab nrov.
Ib yam li ntawd, nws tau nug, yuav ua li cas thaum dilute sulfuric acid yog nchuav rau ntawm phaj tooj liab?
Teb: tooj liab ua tsis hnov mob nrog dilute sulfuric acid . Yog li, tsis muaj qhov tshwm sim tshwm sim thaum twg dilutesulfuric acid yog nchuav ntawm a tooj liab phaj . Tab sis thaum tseem ceeb sulfuric acid yog poured dhau tooj liab , effervescence yog pom. Qhov no tshwm sim vim yog tsim cov roj hydrogen.
Ib sab saum toj, yuav ua li cas thaum dilute sulfuric acid ntxiv rau granulated zinc? Tsis muaj lub sijhawm tshwj xeeb rau ntxiv dilute suhuric kua qaub rau granulated zinc . Tab sis, yog, qhov tshwm sim ntawm cov tshuaj tiv thaiv tau lees paub. Zinc yuav tau dissolved rau form zinc sulphate thiab hydrogen roj yuav raug tso tawm. thaum diluted h2so4 ua ntxiv rau zn cov tshuaj tiv thaiv hauv qab no tshwm sim.
Tsuas yog li ntawd, yuav ua li cas thaum dilute Sulfuric acid yog nchuav rau ntawm Aluminium piece Vim li cas?
Dilute sulfuric acid reacts nrog aluminium hmoov los tsim aluminium sulphate nrog evolution ntawm hydrogen gas.
Puas yog tooj liab reacts nrog sulfuric acid?
tooj liab ua tsis yog teb nrog dilute sulfuric acid raws li nws cov peev xwm txo tau siab dua li ntawm hydrogen. tooj liab ua tsis hloov hydrogen los ntawm non-oxidizing kua qaub zoo li HCl los yog dilute H2SO4 . Yog li, thaum tooj liab yog rhuab nrog conc. H2SO4 , ib redox tshuaj tiv thaiv tshwm sim thiab cov kua qaub Nws raug txo kom sulfurdioxide.

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 tshwm sim thaum boric acid yog rhuab nrog ethanol thiab lub Vapor yog burnt?
Orthoboric acid reacts nrog ethyl cawv nyob rau hauv lub xub ntiag ntawm tsim conc H2SO4 los ua triethylborate. Cov vapors ntawm triethyl borate thaum ignited burns nrog ib tug ntsuab edged nplaim. Qhov no tsim lub hauv paus rau kev tshawb nrhiav borates thiab boric acid hauv kev tshuaj xyuas zoo
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 rau lub parallel phaj capacitor thaum lub dielectric muab tso rau ntawm daim hlau?
Thaum cov khoom siv dielectric tau qhia nruab nrab ntawm daim hlau Thiab thaum cov khoom siv dielectric muab tso rau nruab nrab ntawm daim hlau ntawm cov paib sib npaug ntawm cov phaj capacitor ces vim polarization ntawm cov nqi ntawm ob sab ntawm dielectric, nws tsim hluav taws xob teb ntawm nws tus kheej uas ua nyob rau hauv ib qho kev taw qhia opposite. rau lub teb vim
Yuav ua li cas tshwm sim thaum dilute sulfuric acid ntxiv rau hlau sulfide?
A. Thaum twg ?dilute sulfuric acid ntxiv rau kev sib xyaw ntawm cov hlau txhaws thiab cov hmoov sulfur, cov tshuaj tiv thaiv occusrs ntawm dilute sulfuric acid thiab hlau filings uas tsim ferrous sulphate thiab evolution ntawm hydrogen. FeS tsim reacts nrog sulfuric acid los tsim ferrous sulphate thiab tso tawm hydrogendisulphide gas
