Muaj zog matrix - cov thawv grey sawv cev rau pab pawg ua haujlwm. Tus thawj tswj haujlwm puv sijhawm (Bill) uas yog lub luag haujlwm rau txoj haujlwm ua tiav thiab leej twg muaj txoj cai los txiav txim siab thawj coj ua tus yam ntxwv muaj zog matrix.
Yog li ntawd, dab tsi yog qhov tsis muaj zog matrix?
Thaum lawv piav txog a matrix raws li qaug zog ” nws txhais tau hais tias qhov project manger yog qaug zog (cov thawj coj ua haujlwm yuav pom tias nws muaj zog heev matrix los ntawm lawv qhov kev xav, yog li daim ntawv no feem ntau hu ua kev ua haujlwm matrix ib yam nkaus)
Tsis tas li ntawd, dab tsi yog ib qho chaw matrixed heev? A matrix Lub koom haum qauv yog ib lub tuam txhab qauv uas qhia kev sib raug zoo raug teeb tsa raws li daim phiaj, los yog matrix , es tsis yog nyob rau hauv ib txwm hierarchy. Hauv lwm lo lus, cov neeg ua haujlwm muaj ob qhov kev tshaj tawm kev sib raug zoo - feem ntau rau ob tus neeg saib xyuas kev ua haujlwm thiab tus saib xyuas khoom.
Tsuas yog li ntawd, qhov sib npaug matrix yog dab tsi?
balanced matrix koom haum. Ib tug ob-dimensional tswj qauv ( matrix ) nyob rau hauv uas cov neeg ua hauj lwm raug muab rau ob lub koom haum pab pawg; pab pawg ua haujlwm raws li cov txheej txheem kev txawj uas muaj tus thawj tswj haujlwm ua haujlwm (ntsug) thiab ib pab pawg tshwj xeeb uas cov neeg ua haujlwm tshaj tawm rau tus thawj tswj khoom (kab rov tav).
Peb hom matrix koom haum yog dab tsi?
Muaj peb hom matrix koom haum :ib zog matrix , ib balanced matrix thiab muaj zog matrix . Ib qho tsis muaj zog matrix qauv feem ntau zoo ib yam li kev ua haujlwm koom haum , nrog rau feem ntau ntawm txoj cai nyob rau hauv txhais tes ntawm ib tug functional manager.

Dab tsi yog qhov muaj zog thiab qaug zog acid piav nrog piv txwv?
Cov kua qaub muaj zog sib cais (sib cais) tag nrho hauv dej). Piv txwv li, HCl, cov kua qaub muaj zog yuav tawg mus rau H + thiab Cl-ions. Cov acids tsis muaj zog dissociate ib nrab hauv dej. Piv txwv li, HF, cov kua qaub tsis muaj zog, tsuas yog yuav muaj qee yam ntawm HF cov molecules sib cais thaum twg los tau
Dab tsi yog qhov qaug zog acid thiab muaj zog puag tsim?
Cov ntsev ntawm cov kua qaub tsis muaj zog thiab lub hauv paus muaj zog ua rau hydrolysis hauv dej los tsim OH-ions ntxiv. Txij li thaum acetic acid yog ib qho tsis muaj zog acid, nws tseem unionized nyob rau hauv kev daws thiab cov OH-ions ua rau cov tshuaj yooj yim los yog alkaline. Ib yam li ntawd, ntsev ntawm lub zog acid thiab tsis muaj zog hauv paus yog acidic nyob rau hauv aqueous tov
Txoj cai twg yog txhawm rau muab lub zog saib xyuas muaj zog ntxiv dag zog rau kev ua txhaum cai lij choj tiv thaiv kev ua phem thiab tiv thaiv kev lag luam nyiaj txiag?
COV PHOOJ YWG ACT TEEV NTUJ TEEB MEEM NTAWM TXOJ CAI TXOJ CAI TSHIAB
Piv txwv li, muaj zog acid thiab qaug zog acid yog dab tsi?
Piv txwv ntawm cov acids muaj zog yog hydrochloric acid (HCl), perchloric acid (HClO4), nitric acid (HNO3) thiab sulfuric acid (H2SO4). Cov kua qaub tsis muaj zog tsuas yog qee qhov sib cais, nrog rau ob qho tib si undissociated acid thiab nws cov khoom dissociation tam sim no, nyob rau hauv kev daws, nyob rau hauv equilibrium nrog ib leeg
Vim li cas cov duab ntawm titration nkhaus txawv rau titration ntawm muaj zog acid vs muaj zog puag thiab qaug zog acid vs muaj zog puag?
Cov duab dav dav ntawm titration nkhaus yog tib yam, tab sis pH ntawm qhov sib npaug sib txawv. Hauv qhov tsis muaj zog acid-muaj zog titration, pH yog ntau dua 7 ntawm qhov sib npaug. Hauv qhov muaj zog acid-tsis muaj zog titration, pH tsawg dua 7 ntawm qhov sib npaug
