CHEMISTRY GLOSSARY
Volume ratio yog sib npaug ntim (VA) ntawm ib feem thiab ntim (VB) ntawm lwm yam kev faib ua feem
Ib yam li ntawd, nws tau nug, qhov ntim hauv stoichiometry yog dab tsi?
Cov tshuaj tiv thaiv tshuaj nquag feem ntau suav nrog ob qho khoom siv uas nws qhov loj tuaj yeem ntsuas tau thiab cov roj cua uas ntsuas qhov ntsuas. ntim yog tsim nyog. Stoichiometry teeb meem ntawm hom no hu ua Bothmass- ntim los yog ntim - cov teeb meem loj. loj ofgiven → moles ntawm muab → moles ntawm tsis paub → ntim ntawm tsis paub.
Ib yam li ntawd, vim li cas thaj chaw saum npoo rau qhov sib piv ntawm qhov tseem ceeb? Cov tseem ceeb point yog tias qhov thaj chaw saum npoo mus rau ntim ratio tau txais me me raws li lub cell tau loj dua. Yog li, yog tias lub cell loj hlob dhau ib qho kev txwv, cov khoom tsis txaus yuav tuaj yeem hla cov membrane sai txaus kom haum rau cov cellular ntxiv. ntim.
Tom qab ntawd, lo lus nug yog, ua li cas koj xam qhov chaw rau ntim piv?
Koj coj lub qauv rau nto cheeb tsam thiab koj faib nws los ntawm qauv rau ntim . Nov yog qhov koj tau txais: Koj siv qhov no piv ib yam li koj xav rau thecube. Yog tias koj muaj lub vojvoog ntawm 1 centimeter rau a ntim ntawm 4.187 cubic centimeters, ces koj nto - thaj tsam-rau- volumeratio yog 3/1 = 3.
Qhov zoo li cas muaj qhov ntim ntau tshaj?
Ntawm tag nrho cov tsis tu ncua polygons nrog vaj huam sib luag perimeter, qhov onewith the feem ntau sab muaj qhov loj tshaj cheeb tsam. Ib lub voj voog muaj ib cheeb tsam ntau dua li ib txwm polygon ntawm tib lub voj voog. Ib tug kheej kheej muaj ntau dua ntim tshaj solidfigures nrog tib qhov chaw.
