Lub hauv paus muaj zog zoo li sodium hydroxide ( NaOH ) tseem yuav sib ncaim kiag li rau hauv dej ; yog tias koj muab tso rau hauv 1 mole ntawm NaOH rau hauv dej , koj yuav tau txais 1 mole ntawm hydroxide ions. Qhov muaj zog acid yog, qhov qis dua pH nws yuav tsim nyob rau hauv kev daws.
Kuj paub yog, puas NaOH ionize hauv dej?
NaOH yog Arrhenius puag vim nws dissociates nyob rau hauv dej muab cov hydroxide (OH-thiab sodium (Na+) cov. Yog li Arrhenius acid yog ib yam khoom uas ionizes thaum nws dissolves nyob rau hauv dej muab H+los yog hydrogen, ion.
Ib yam li ntawd, puas yog lub hauv paus ionize hauv dej? Ib tug muaj zog puag yog a puag , qho ionizes tag nrho nyob rau hauv ib tug aqueous tov. Feem ntau muaj zog hauv paus yog cov hlau hydroxide soluble xws li potassium hydroxide. Calcium hydroxide tsuas yog me ntsis soluble hauv dej , tab sis qhov feem ntawd ua yaj kuj dissociates rau hauv ions.
Yog li ntawd, dab tsi tsis zoo ion raug tsim thaum sodium hydroxide yaj hauv dej?
Thaum twg sodium hydroxide ( NaOH ) dissolves nyob rau hauv dej , nws cais mus rau hauv qhov zoo - them sodium ions (cations) thiab tsis zoo - them hydroxide ions (anions).
Puas muaj cov electrolytes uas muaj zog ionize hauv dej?
Electrolytes yog cov khoom uas, thaum yaj hauv dej , tawg mus rau hauv cations (ntxiv-them ions) thiab anions (rho tawm ions). Peb hais lawv ua ionize . Muaj zog electrolytes ionize tag nrho (100%), thaum tsis muaj zog electrolytes ionize tsuas yog ib feem (feem ntau yog nyob rau hauv qhov kev txiav txim ntawm 1-10%).

Yog vim li cas combustion tiav yog zoo dua li tsis tiav combustion?
Tsis tiav combustion tshwm sim thaum cov khoom cua lossis oxygen tsis zoo. Dej tseem tsim, tab sis carbon monoxide thiab carbon yog tsim los ntawm carbon dioxide. Cov pa roj carbon yog tso tawm raws li cov kua qaub. Cov pa roj carbon monoxide yog cov pa tshuaj lom, uas yog ib qho laj thawj vim li cas kev sib xyaw ua tiav yog nyiam rau kev ua tsis tiav
Dab tsi yog ua tiav dominance tsis tiav dominance thiab Codominance?
Nyob rau hauv tag nrho dominance, tsuas yog ib tug allele nyob rau hauv lub genotype yog pom nyob rau hauv lub phenotype. Nyob rau hauv codominance, ob alleles nyob rau hauv lub genotype yog pom nyob rau hauv lub phenotype. Nyob rau hauv tsis tiav dominance, ib tug sib tov ntawm alleles nyob rau hauv lub genotype yog pom nyob rau hauv lub phenotype
Yuav ua li cas koj pom qhov ntim ntawm cov dej hauv ib lub tog raj kheej kawm tiav?
Ncuav dej txaus los ntawm koj lub khob rau hauv lub tog raj kheej kawm tiav kom ncav cuag qhov siab uas yuav npog cov qauv. Nyeem thiab sau lub ntim. Tig me ntsis lub tog raj kheej tiav thiab ua tib zoo muab cov qauv tso rau hauv dej. Muab lub cylinder kawm tiav rau ntawm lub rooj thiab saib cov qib dej
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
Vim li cas cov acids muaj zog ionize tag nrho hauv dej?
Qhov no feem ntau txhais tau hais tias nyob rau hauv aqueous tov ntawm tus qauv kub thiab siab, lub concentration ntawm hydronium ions yog sib npaug zos rau cov concentration ntawm muaj zog acid qhia rau cov tshuaj. Ionization ntawm cov kua qaub thiab cov hauv paus hauv dej: Cov kua qaub muaj zog ionizes tag nrho hauv cov kua dej los ntawm kev poob ib qho proton (H +)
