m - nitroaniline Nws yog soluble nyob rau hauv ether, txawm tias lub aqueous txheej yooj yim ,vim a puag nyob puag hauv puag . Bases (eg., m - nitroaniline ,qus a puag vim hais tias nws yog ib tug proton txais) ua zoo them thaum reacted nrog ib tug acid, thiab no zoo them ion tam sim no yuav muab faib mus rau hauv lub aqueous txheej.
Hauv qhov no, dab tsi yog conjugate acid ntawm M nitroaniline?
Lub conjugate acid ntawm m-nitroaniline thiab cov conjugate puag ntawm sulfuric acid xav tias yuav nyob rau hauv lub aqueous tov. Qhov no yog xaus vim hais tias m-nitroaniline yog lub hauv paus, uas reacted nrog hydrosulfuric acid.
Tom qab ntawd, lo lus nug yog, vim li cas NaOH siv hauv kev rho tawm? Qhov tshwm sim no feem ntau yuav pom yog tias sodium bicarbonate yog siv rau cov rho tawm thiaj li yuav neutralize los yog tshem tawm acidic tebchaw. Cov tshuaj tiv thaiv them nyiaj carbon dioxide (CO2), uas yog ib qho roj ntawm ambient kub. Lub siab ua kom thawb qee cov roj thiab cov kua tawm.
Kuj Paub, yog Naphthalene yog lub hauv paus lossis kua qaub?
Cov hydrocarbon, ua nruab nrab, tsis yaj hauv lub hauv paus, nyob hauv qab hauv methylene chloride. Evaporation ntawm methylene chloride tawm ntawm naphthalene li crystals. Ces, koj ntxiv hydrogen chloride ua kom cov dej sodium benzoate hmoov kua qaub.
Puas yog benzoic acid soluble hauv 6m NaOH?
Benzoic acid tau pom tias yog soluble hauv dej thiab 1.0 M NaOH Txawm li cas los xij, thaum ntxiv 6.0 M HCl rau cov tshuaj no, benzoic acid ua insoluble.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Puas yog calcium cyanide yog cov kua qaub lossis lub hauv paus?
Calcium cyanide decomposes rau tsis tshua muaj tshuaj lom thiab flammable hydrogen cyanide thiab tshuaj lom thiab irritating nitrogen oxides thaum rhuab hauv hluav taws. QHOV 9. Lub cev thiab tshuaj lom neeg. Lub cev lub cev: Lub hauv paus ruaj khov: Reacts maj mam nrog dej los tsim calcium hydroxide, uas yog lub hauv paus muaj zog
Puas yog lub hauv paus square ntawm 9 31 yog tus lej irrational?
Teb: Tsis yog, 9/31 tsis yog tus lej irrational. Qhov twg, ob qho tib si p thiab q yog integers thiab q ≠ 0, Txwv tsis pub, nws yog hu ua irrational tooj
Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?
Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus
Koj puas tuaj yeem muab lub voos xwmfab hauv paus los ntawm lub hauv paus square?
Cov Khoom Muag tau nce mus rau Txoj Cai Fais Fab yog qhov tseem ceeb vim tias koj tuaj yeem siv nws los faib cov lus qhia radical. Nco ntsoov tias cov hauv paus hniav zoo ib yam - koj tuaj yeem muab cov hauv paus plaub hau nrog cov hauv paus plaub hau, lossis cov hauv paus hniav nrog lub voos xwmfab, piv txwv li. Tab sis koj tsis tuaj yeem muab lub hauv paus square thiab lub voos xwmfab hauv paus siv txoj cai no
