tshuaj muaj zog (acidity, basicity, combustibility, reactivity).
Puas yog tshuaj lom neeg lossis lub cev khoom?
Acids thiab Bases yog dab tsi? Cov kua qaub yog cov tshuaj lom neeg uas muaj cov qaub saj hauv qhov nruab nrab aqueous. Lawv muaj lub siab xav tig xiav litmus liab. Ntawm qhov tod tes, cov hauv paus yog tshuaj lom neeguas yog tus cwj pwm los ntawm kev iab saj thiab nplua rau qhov kov.
Puas yog acidity hloov lub cev lossis tshuaj lom neeg?
Kev hloov ntawm ib hom teeb meem mus rau lwm yam (lossis tsis muaj peev xwm hloov tau) yog tshuaj muaj tshuaj. Piv txwv ntawm cov khoom siv tshuaj muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion.
Puas buoyancy yog lub cev lossis tshuaj lom neeg?
Qee lub cev muaj zog suav nrog huab hwm coj, ntim, ntom, thiab buoyancy.
Puas yog kev hloov pauv lub cev lossis tshuaj lom neeg?
A lub cev hloov pauv tshwm sim thaum muaj teeb meem hloov qhov loj, duab, lossis daim ntawv. Koj tuaj yeem hloov lub cev rau cov av nplaum los ntawm molding nws mus rau hauv lub lauj kaub los yog flattening nws tawm. Cov khoom tseem yog av nplaum-nws cov duab tsuas yog txawv. Cov tshuaj kuj muaj qee yam khoom qub.

Yam thiols yog dab tsi? 1 BIOLOGICAL THIOLS Thiols xa mus rau chav kawm ntawm cov organic sulfur derivatives uas yog tus cwj pwm los ntawm qhov muaj sulfhydryl residues (–SH) ntawm lawv qhov chaw nquagTshuaj, thiols yog mercaptans (C-SH) thiab biological mercaptans feem ntau hu ua biological thiols lossis biothio
Lub sijhawm hloov pauv ntawm dna cov tshuaj lom neeg puas tawg?
Denaturation ntawm DNA tshwm sim thaum tsis muaj zog hydrogen bondsntawm ob lub strands raug cuam tshuam thiab cov molecule ua ib leeg tso tseg. Yog li tus nqi ntawm denaturation yog nyob ntawm qhov feem ntawm G + C piv rau A + T hauv paus.
Puas tawg yog tshuaj lom neeg lossis lub cev?
nruj me ntsis txheej txheem lub cev, as opposed to chemical or nuclear, e.g., qhov tawg ntawm lub thawv kaw lossis ib nrab ntim ntim hauv qab lub siab feem ntau hu ua kev tawg . Puas tawg lub cev? tawg yog lub cev tshwm sim uas ua rau lub zog tso tawm sai sai;
Puas yog tshuaj lom ib qho lus qhia lossis lub npe?
