Reactants thiab cov khoom nyob rau hauv Tshuaj Reactions. Ina tshuaj tiv thaiv, tshuaj (cov ntsiab lus thiab/los yog cov tebchaw) hu ua reactants hloov mus rau lwm yam khoom (compoundsand/los yog cov khoom) hu ua cov khoom . Koj tsis tuaj yeem hloov ib qho mus rau lwm qhov hauv cov tshuaj tiv thaiv tshuaj - uas tshwm sim innuclear cov tshuaj tiv thaiv.
Tsuas yog li ntawd, lub ntsiab lus ntawm reactant thiab khoom yog dab tsi?
Los ntawm Reactants rau Khoom Reactants yog cov khoom uas pib chemicalreaction. Cov khoom yog cov khoom uas tsim nyob rau hauv qhov kev ua.
Ib sab saum toj no, cov piv txwv ntawm reactants thiab cov khoom yog dab tsi? Los ntawm Reactants rau Cov khoom Thaum lub tswm ciab hlawv, lub reactants yog roj (thecandlewick thiab wax) thiab oxygen (hauv huab cua). Cov cov khoom yog carbon dioxide gas thiab dej vapor.
Ntxiv mus, dab tsi yog cov khoom hauv science?
Hauv chemistry, a khoom yog ib yam khoom uas yog tsim los ntawm cov tshuaj tiv thaiv tshuaj. Hauv cov tshuaj tiv thaiv, cov khoom pib hu ua reactants cuam tshuam nrog ib leeg.
Ib qho piv txwv ntawm reactant yog dab tsi?
Nyob rau hauv cov xwm txheej zoo, xws li qhov kub thiab txias, lub sijhawm, los yog siab, cov khoom siv tshuaj lom neeg ntawm lub reactants tawg, thiab cov atoms tsim tshiab bonds uas muab sib txawv ua ke. Cov khoom uas tshwm sim los ntawm qhov kev sib txuas ntawm cov atoms no hu ua cov khoom ntawm cov tshuaj tiv thaiv. Piv txwv - NH3 + HCL → NH4Cl.

Dab tsi yog cov khoom thiab reactant hauv kev sib npaug tshuaj?
Tag nrho cov tshuaj tiv thaiv muaj xws li cov reactants thiab cov khoom. Reactants yog cov tshuaj uas pib ua cov tshuaj tiv thaiv tshuaj, thiab cov khoom yog cov tshuaj uas tsim tawm hauv cov tshuaj tiv thaiv
Dab tsi yog qhov txawv ntawm ib qho ultramafic ib qho mafic nruab nrab thiab felsic pob zeb?
Hauv cov txheej txheem kev faib tawm silica-cov ntsiab lus dav dav, pob zeb nrog ntau dua 65 feem pua silica hu ua felsic; cov uas muaj li ntawm 55 thiab 65 feem pua silica yog nruab nrab; cov uas muaj li ntawm 45 thiab 55 feem pua silica yog mafic; thiab cov uas tsawg dua 45 feem pua yog ultramafic
Dab tsi yog 4 yam khoom ntawm ib qho khoom?
Muaj plaub hom crystalline solids: molecular solids, network solids, ionic solids, thiab metallic solids. Ib qho khoom ntawm cov qauv atomic-theem thiab muaj pes tsawg leeg txiav txim siab ntau yam ntawm nws cov khoom macroscopic, xws li, piv txwv li, hluav taws xob thiab hluav taws xob conductivity, ntom, thiab solubility
Yam khoom twg ua rau hluav taws xob hauv ob qho tib si khoom thiab molten?
Cov delocalized electrons no muaj nyob rau hauv ob qho tib si ib qho khoom thiab molten, yog li sodium tuaj yeem ua hluav taws xob hauv ob lub xeev. Sodium iodide yog heteroatomic, thiab electronegativity sib txawv ntawm sodium thiab iodide ua rau lawv cov nyiaj ionic. Ionic compounds tsim qhov hu ua crystal lattice qauv
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
