Ntxiv dej rau acid los yog puag yuav hloov nws cov pH. Dej feem ntau yog dej molecules yog li ntawd ntxiv dej rau acid los yog puag txo cov concentration ntawm ions hauv cov tshuaj. Ib yam li ntawd, thaum alkali yog diluted nrog dej qhov concentration ntawm OH - ions txo qis.
Ntawm no, yuav ua li cas tshwm sim thaum lub hauv paus muab tso rau hauv dej?
Bases yog cov tshuaj sib txuas uas nyiam hydrogen atoms thaum lawv nyob muab tso rau hauv dej . Ib qho piv txwv ntawm a puag yog sodium hydroxide (NaOH). Thaum cov khoom no yog muab tso rau hauv dej , nws nyiam hydrogen ions, thiab ib qho yooj yim (los yog alkaline) daws tau raws li hydroxyl (–OH) ions ions accumulates.
Tom qab ntawd, lo lus nug yog, yuav ua li cas tshwm sim thaum cov kua qaub thiab lub hauv paus ntxiv rau dej? Acid - Puag Cov tshuaj tiv thaiv. Thaum ib acid thiab base muab tso ua ke, lawv hnov qab neutralize lub kua qaub thiab puag khoom, ua ib tug ntsev. Lub H(+) cation ntawm lub kua qaub ua ke nrog OH(-) anion ntawm lub puag ua form dej . Lub compound tsim los ntawm cation ntawm lub puag thiab anion ntawm lub kua qaub hu ua ntsev.
Kuj nug, ua li cas thaum lub hauv paus tsis muaj zog ntxiv rau dej?
Ib qho piv txwv ntawm a tsis muaj zog puag yog ammonia. Nws tsis muaj hydroxide ions, tab sis nws reacts nrog dej los tsim ammonium ions thiab hydroxide ions. Txoj hauj lwm ntawm equilibrium txawv ntawm puag rau puag thaum a tsis muaj zog puag reacts nrog dej . Qhov ntxiv mus rau sab laug nws yog, lub weaker lub puag.
Yuav ua li cas thaum acid ntxiv rau dej?
Cov cua kub ntau yog tso tawm thaum muaj zog kua qaub yog tov nrog dej . Ntxiv ntau kua qaub tso cua sov ntau. Yog koj ntxiv dej rau kua qaub , koj tsim ib tug heev concentrated tov ntawm kua qaub pib. Thaum tshav kub kub tso tawm ntau npaum li cas cov tshuaj yuav boil heev hnyav, splashing concentrated kua qaub tawm ntawm lub thawv!

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
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
Dab tsi ua rau DNA tshiab strand los ntawm kev ntxiv cov hauv paus ntxiv?
Glossary DNA ligase: cov enzyme uas catalyzes koom nrog DNA tawg ua ke. DNA polymerase: ib qho enzyme uas tsim cov strand tshiab ntawm DNA ntxiv rau cov qauv strand. helicase: ib qho enzyme uas pab qhib DNA helix thaum DNA replication los ntawm kev rhuav tshem cov hydrogen bonds
Yuav ua li cas depositional feature thaum ib tug kwj nkag mus rau hauv lub pas dej los yog dej hiav txwv?
Nqe lus piav qhia: Lub delta yog cov av uas tsim los ntawm cov txheej txheem ntawm kev tso cov sediments uas nqa los ntawm cov dej ntws dawb los ntawm cov av
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
