pH txhais: ib daim duab qhia txog cov acidity los yog alkalinity ntawm cov tshuaj ntawm ib tug logarithmic scale uas 7 yog nruab nrab, qis tus nqi yog ntau cov kua qaub thiab cov nqi siab dua alkaline. Cov pH yog sib npaug rau −log10 c, qhov c yog cov hydrogen ion concentration hauv moles ib liter. Yog li pH 2 yog 1000 npaug zog dua pH 5.
Ib yam li ntawd, tib neeg nug, pes tsawg zaus acidic yog pH ntawm 2 tshaj 4?
Txij li thaum 10 -2 = ( 100 ) 10 -4, qhov concentration ntawm [H3O+] yog 100 lub sij hawm zoo ntawm pH = 2 tshaj ntawm pH = 4, yog li cov kua qaub yog 100 lub sij hawm muaj zog ntawm pH = 2 tshaj ntawm pH = 4.
Ib yam li ntawd, pes tsawg zaus acidic yog pH ntawm 3 piv rau PH ntawm 5? Qhov pH nplai yog logarithmic, txhais tau hais tias qhov nce lossis txo qis ntawm tus nqi sib npaug hloov qhov concentration los ntawm kaum npaug. Piv txwv li, pH ntawm 3 yog kaum lub sij hawm ntau acidic tshaj pH ntawm 4. Ib yam li ntawd, pH ntawm 3 yog ib puas lub sij hawm ntau acidic tshaj pH ntawm 5.
Tom qab ntawd, ib tus tuaj yeem nug, pes tsawg zaus acidic yog pH ntawm 2 piv rau 6?
A pH ntau dua 7 yog qhov yooj yim. Cov pH scale yog logarithmic thiab yog li ntawd, txhua tag nrho pH tus nqi qis dua 7 yog kaum lub sij hawm ntau acidic tshaj tus nqi siab dua tom ntej. Piv txwv li, pH 4 yog ten lub sij hawm ntau acidic tshaj pH 5 thiab 100 sij hawm (10 sij hawm 10) ntau acidic tshaj pH 6.
Muaj pes tsawg zaus acidic yog pH ntawm 3 tshaj 6?
1 Teb. Cov tshuaj uas nws pH = 3 yog 1000 sij hawm raws li acidic raws li cov tshuaj uas nws pH = 6.

Dab tsi yog rau qhov sib txawv loj ntawm lub koom haum los ntawm qhov tsawg tshaj plaws mus rau loj tshaj plaws ecologists?
Lub koom haum loj yog dab tsi, los ntawm qhov tsawg tshaj plaws mus rau qhov loj, uas cov kws tshawb fawb feem ntau kawm? 6 theem sib txawv ntawm lub koom haum uas ecologists nquag kawm yog hom, pejxeem, zej zog, ecosystem, thiab biome
Muaj pes tsawg zaus nws lub cev ntev tuaj yeem dhia tau?
Cov nyom tuaj yeem dhia 200 npaug ntawm nws lub cev. Nws yog TRUE. Nrog lawv ob txhais ceg muaj zog, cov nyom tuaj yeem dhia ntawm 16 thiab 23 ft. (5 thiab 7 m) lossis 200 npaug ntawm lawv tus kheej
Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?
Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus
Qhov twg electromagnetic yoj muaj qhov luv tshaj wavelength thiab siab tshaj plaws zaus?
Gamma rays muaj lub zog siab tshaj plaws, qhov luv tshaj wavelengths, thiab cov zaus siab tshaj plaws. Cov xov tooj cua tsis muaj zog, ntawm qhov tod tes, muaj lub zog qis tshaj plaws, qhov ntev tshaj plaws wavelengths, thiab qis tshaj zaus ntawm txhua hom EM hluav taws xob
Muaj pes tsawg hom tshuaj lom neeg muaj pes tsawg leeg?
Hauv chaw ua haujlwm muaj ob hom kev phom sij: kev noj qab haus huv thiab kev phom sij ntawm lub cev
