Corrosive yog hais txog ib yam khoom uas muaj hwj chim los ua kom tsis muaj kev puas tsuaj los yog rhuav tshem lwm yam khoom los ntawm kev sib cuag. Kuj Paub Raws li: Corrosive chemicals kuj tseem hu ua " caustic ", txawm tias lub sij hawm caustic feem ntau siv rau cov hauv paus muaj zog thiab tsis yog acids lossis oxidizers.
Tsis tas li ntawd, qhov txawv ntawm caustic thiab corrosive yog dab tsi?
A caustic yuav ua rau cov ntaub so ntswg puas ntsoog, tab sis tsis tas yuav ua rau cov ntaub ntawv inorganic xws li hlau lossis iav. A corrosive tuaj yeem ua rau cov khoom tsis zoo thiab cov organic.
Ib yam li ntawd, dab tsi yog caustic heev? caustic . Siv lub adjective caustic los piav txog tej yam tshuaj uas muaj peev xwm hlawv cov nqaij mos los yog lwm yam tshuaj, los yog, piv txwv li, ib nqe lus uas muaj qhov zoo sib xws. Caustic hauv qhov kev nkag siab no txhais tau tias hnyav heev. Hauv kev nkag siab tshuaj lom neeg, qhov ze ntawm lub ntsiab lus yog corrosive.
Kuj paub yog, dab tsi yog corrosive txhais li cas hauv chemistry?
A corrosive cov khoom yog ib yam khoom uas muaj reactive heev uas ua rau pom kev puas tsuaj rau cov ntaub so ntswg nyob. Corrosives ua ncaj qha, los ntawm chemically rhuav tshem ib feem (oxidation), los yog tsis ncaj los ntawm kev ua o. Cov kua qaub thiab cov hauv paus yog feem ntau corrosive cov ntaub ntawv.

Cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas thiab lawv cuam tshuam li cas?
Hydrophobic txhais tau hais tias cov molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic, txhais tau tias lawv nyob hauv daim nyias nyias. Hydrophilic txhais tau hais tias cov molecule muaj affinity rau dej
Vim li cas A thiab T thiab G thiab C ua khub hauv DNA ob lub helix?
Qhov no txhais tau hais tias txhua ntawm ob strandsindouble-stranded DNA ua raws li ib tug templatetoproduce ob strands tshiab. Replication relies oncomplementary basepairing, uas yog lub hauv paus ntsiab lus piav qhia los ntawmChargaff cov cai: adenine (A) ib txwm khi nrog thymine (T) thiab cytosine (C) ib txwm khi nrog guanine (G)
Qhov nqus thiab tso tawm ntawm lub zog cuam tshuam li cas rau qhov kub thiab txias thaum lub sij hawm muaj tshuaj tiv thaiv?
Nyob rau hauv endothermic cov tshuaj tiv thaiv cov enthalpy ntawm cov khoom yog ntau dua cov enthalpy ntawm cov reactants. Vim tias cov tshuaj tiv thaiv tso tawm lossis nqus lub zog, lawv cuam tshuam rau qhov kub ntawm lawv ib puag ncig. Exothermic cov tshuaj tiv thaiv cua sov ua rau lawv ib puag ncig thaum cov tshuaj tiv thaiv endothermic txias rau lawv
Dab tsi yog qhov txawv ntawm Arrhenius txhais thiab brønsted Lowry txhais ntawm acids thiab bases?
Qhov txawv ntawm peb txoj kev xav yog qhov kev xav Arrhenius hais tias cov kua qaub ib txwm muaj H + thiab cov hauv paus ib txwm muaj OH-. Thaum tus qauv Bronsted-Lowry thov tias cov kua qaub yog cov neeg pub dawb proton thiab cov neeg txais kev lees paub yog li cov hauv paus tsis tas yuav muaj OH- yog li cov kua qaub pub ib qho proton rau dej tsim H3O +
Vim li cas thiaj muaj qhov kub thiab txias thaum lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg?
Thaum lub sab qaum teb ib nrab ntawm lub ntiaj teb yog tilted mus rau lub hnub, lub sab qab teb hemisphere yog tilted. Cov neeg nyob rau yav qab teb hemisphere tau ntsib lub hnub luv luv thiab txias dua ntawm lub caij ntuj no. Thaum lub caij nplooj zeeg thiab caij nplooj ntoos hlav, qee qhov chaw hauv ntiaj teb muaj kev zoo sib xws, me me, muaj xwm txheej
