Ntawm txhua NFPA Label , yuav tsum muaj tus lej ntawm xoom mus rau plaub hauv thaj chaw xiav, liab thiab daj. Cov lej qhia txog qib ntawm ib qho tshwj xeeb phom sij . Cov yam khoom yog qhov mob hnyav heev yog tias tus yam khoom yog tsis tuav yam xyuam xim.
Ntxiv rau qhov no, cov ntaub ntawv dab tsi ua rau cov tshuaj lom neeg muaj kev phom sij thiab MSDS muaj sib xws?
Hauv MSDS muaj ntau lub ntsiab lus tseem ceeb suav nrog:
- tus kheej ntawm cov khoom siv thiab lub tuam txhab muab khoom.
- Kev txheeb xyuas cov kev phom sij los ntawm cov khoom muaj xws li: kev faib tawm (irritant, corrosive, thiab lwm yam),
- muaj pes tsawg leeg ntawm cov ntaub ntawv (cov khoom siv tshuaj: muaj zog, corrosive thiab hygroscopic oxidizing agents.
Cov lej txhais li cas ntawm cov paib phom sij? Cov tus lej nyob rau hauv thawj peb qhov chaw nyob ntawm 0 mus rau 4, nrog 0 signifying no phom sij thiab 4 qhia tias mob hnyav phom sij . Piv txwv li, hauv cheeb tsam Reactivity: 0 = Stable. 1 = Tsis ruaj tsis khov yog tias cua sov. 2 = Cov tshuaj phem heev.
Ntawm no, cov xim dab tsi sawv cev rau ntawm daim ntawv cim tshuaj lom neeg?
Ntau tus neeg muag khoom siv a xim coding system rau tshuaj kev faib khoom cia. Txhua lub tuam txhab siv cov xim liab rau flammability, xiav rau kev noj qab haus huv, thiab daj rau reactivity raws li coj los ntawm National Fire Protection Association ( NFPA ) xim code system. Feem ntau tshuaj cov neeg muag khoom siv dawb rau kev sib cuag phom sij.
Lub Pob Zeb Diamond Label yog dab tsi?
The NFPA pob zeb diamond muab kev pom sai sai ntawm kev phom sij rau kev noj qab haus huv, flammability, reactivity, thiab kev phom sij tshwj xeeb uas tshuaj tuaj yeem tsim thaum lub sijhawm a hluav taws . The NFPA pob zeb diamond muaj plaub xim-coded teb: xiav, liab, daj, thiab dawb. Daim teb dawb yog siv los qhia cov xwm txheej tshwj xeeb.

Yuav ua li cas yog daim ntawv cog lus sib txawv ntawm daim ntawv cog lus ionic?
Qhov sib txawv ntawm cov ionic thiab covalent daim ntawv cog lus yog tias covalent daim ntawv cog lus yog tsim thaum ob lub atoms sib koom electrons. Ionic bonds yog lub zog uas tuav ua ke electrostatic zog ntawm kev nyiam ntawm cov ions oppositely them. Ionic bonds muaj qhov sib txawv electronegativity ntau dua lossis sib npaug li 2
Yuav ua li cas koj nyeem ib tsab ntawv tsa suab?
VIDEO Ib yam li ntawd, dab tsi yog qhov hloov pauv thiab lub sijhawm teeb tsa? Qhov chaw nruab nrab ntawm qhov nrawm- lub sijhawm ua haujlwm thiab cov ` sij hawm ' axis muab cov hloov chaw ntawm qhov khoom. Txoj kev nqes hav yog tib yam li ntawm A mus rau C, yog li tus neeg caij tsheb kauj vab qhov nrawm yog tas li ntawm tag nrho.
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Yuav ua li cas koj sau txoj kab nqes nqes intercept daim ntawv nyob rau hauv tus qauv daim ntawv?
Standard form yog lwm txoj hauv kev los sau daim ntawv nqes hav-intercept (as opposed to y=mx+b). Nws sau li Ax+By=C. Koj tuaj yeem hloov daim ntawv nqes hav-intercept rau cov qauv zoo li no: Y=-3/2x + 3. Tom ntej no, koj cais qhov y-intercept (qhov no nws yog 2) zoo li no: Ntxiv 3/2x rau txhua sab ntawm kab zauv kom tau qhov no: 3/2x + y = 3
Yuav ua li cas koj yuav tsum siv ib daim ntawv qhia txog lub npe tshuaj compound?
Yuav ua li cas koj yuav tsum siv ib daim ntawv qhia txog lub npe tshuaj compound? Txhawm rau sau npe los yog sau nws cov qauv, ua raws cov kab kos hauv cov duab 9.20 thiab 9.22 rau lub npe tiag tiag lossis qauv
