Kev rho tawm (Tsis yog Kev sib txuas lus )
Tsis tas li ntawd, kev faib, kev sib xyaw ntawm cov dej num thiab matrix kev sib npaug yog ob tug paub zoo piv txwv uas tsis yog kev sib txuas lus ..
Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog qhov piv txwv ntawm cov khoom sib txuas ntawm kev sib npaug?
Cov commutative khoom ntawm multiplication hais tias koj tuaj yeem muab tus lej sib npaug hauv txhua qhov kev txiav txim. Hauv lus Askiv rau kev mus los txhais tau tias mus ncig lossis hloov chaw. Hauv lej, cov commutative khoom ntawm multiplication tso cai rau peb hloov qhov chaw ntawm yam khoom hauv ib yam khoom. Rau piv txwv 2 x 3 = 6.
Ib yam li ntawd, piv txwv ntawm cov cuab yeej cuab tam yog dab tsi? Raws li cov associative khoom ntawm qhov ntxiv, cov lej ntawm peb lossis ntau dua tus lej tseem zoo ib yam txawm hais tias cov lej tau muab faib li cas. Ntawm no yog ib qho piv txwv ntawm yuav ua li cas cov sum tsis hloov txawm hais tias yuav ua li cas cov addends yog grouped. Nov yog lwm qhov piv txwv . (75 + 81) + 34. = 166 + 34.
Nyob rau hauv txoj kev no, dab tsi yog cov khoom sib txuas rau cov menyuam yaus?
Cov commutative khoom ntawm kev sib faib hais tias koj tuaj yeem muab cov lej sib npaug hauv ib qho kev txiav txim thiab cov lus teb yuav ib txwm zoo ib yam.
Dab tsi yog qhov khoom tsis sib xws?
Kev ua haujlwm binary ntawm lub teeb S hu ua kev sib txuas lus yog tias: Ib qho haujlwm uas tsis txaus siab rau saum toj no vaj tse hu ua tsis yog - kev sib txuas lus.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi ntawm cov khoom sib txuas sib txuas muaj nyob ntawm cov dej molecules?
Piv txwv li, dej molecules yog tuav ua ke los ntawm hydrogen bonds ntawm hydrogen atom ntawm ib lub molecule thiab cov pa atom ntawm lwm tus (daim duab: hydrogen bonds). Hydrogen bonds yog ib qho muaj zog intermolecular quab yuam thiab muaj zog dua lwm cov dipole-dipole rog
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
