A tshuaj tiv thaiv -los yog tshuaj kev hloov pauv-yog cov txheej txheem uas qee yam tshuaj hloov mus rau lwm tus, hloov lawv tshuaj muaj pes tsawg leeg thiab lawv tshuaj daim ntawv cog lus.
Hais txog qhov no, lub hom phiaj ntawm cov tshuaj tiv thaiv kab mob yog dab tsi?
Lub Hom Phiaj : Cov lub hom phiaj ntawm no kev sim yog ua, sib npaug thiab faib tshuaj tiv thaiv raws li kev soj ntsuam. Cov tub ntxhais kawm yuav txiav txim siab txog kev txheeb ze ntawm ntau lub ntsiab lus hlau thiab tus kheej ntawm ib qho tsis paub ionic compound raws li nws tshuaj khoom.
Ib yam li ntawd, qhov tshuaj tiv thaiv txias tshaj plaws yog dab tsi? 3. Cesium thiab Dej . Cesium yog ib qho ntawm feem ntau reactive alkali hlau. Thaum nws los rau hauv kev sib cuag nrog dej , nws reacts tsim cesium hydroxide thiab hydrogen gas.
Ib yam li ntawd, ib qho piv txwv ntawm cov tshuaj tiv thaiv tshuaj yog dab tsi?
A tshuaj tiv thaiv tshwm sim thaum ib los yog ntau tshaj tshuaj hloov mus rau ib qho lossis ntau dua lwm tus tshuaj . Piv txwv : hlau thiab oxygen combining ua xeb. vinegar thiab ci dej qab zib combining ua sodium acetate, carbon dioxide thiab dej.
Peb tuaj yeem txheeb xyuas ntau hom tshuaj tiv thaiv kab mob li cas?
Hom tshuaj tiv thaiv
- Synthesis cov tshuaj tiv thaiv. Ob los yog ntau tshaj reactants ua ke los ua 1 yam khoom tshiab.
- Cov tshuaj tiv thaiv decomposition. Ib qho reactant tawg ua 2 lossis ntau dua cov khoom.
- Kev hloov pauv ib zaug.
- Kev hloov pauv ob zaug.
- Cov tshuaj tiv thaiv combustion.

Dab tsi yog qhov sib txawv ntawm cov xwm txheej tag nrho thiab qhov chaw coj mus kuaj?
Qhov chaw piv txwv ntawm kev sim yog cov txheej txheem ntawm txhua qhov ua tau. Yog tias qhov kev sim pov tseg tuag, qhov chaw piv txwv yog {1, 2, 3, 4, 5, 6}. Exhaustive Txheej xwm. Ib lossis ntau qhov xwm txheej tau hais kom tag nrho thaum lawv zoo li qhov tsawg kawg yog ib qho ntawm cov xwm txheej tau tshwm sim
Qhov chaw kuaj mob yog dab tsi?
Cov chaw kuaj mob yog txhua qhov chaw uas tus neeg kawm muaj peev xwm cuam tshuam nrog cov ntaub ntawv thiab / lossis cov qauv kom saib xyuas thiab nkag siab cov ntsiab lus ntawm tes (Myers, 2005)
Lub npe ntawm cov enzyme uas kuaj pom hauv qhov kev kuaj pom zoo catalase yog dab tsi?
Catalase Test- Ntsiab Cai, Siv, Txheej Txheem, Txhais Lus Txhais nrog ceev faj. Qhov kev sim no qhia pom tias muaj catalase, ib qho enzyme uas ua rau cov pa tawm ntawm cov pa oxygen los ntawm hydrogen peroxide (H2O2)
Dab tsi yog qhov subset ntawm qhov chaw coj mus kuaj?
Cov txheej txheem ntawm tag nrho cov txiaj ntsig tau raug hu ua qhov chaw piv txwv ntawm qhov kev sim thiab feem ntau yog qhia los ntawm S. Ib qho subset E ntawm qhov chaw qauv S yog hu ua ib qho kev tshwm sim. Nov yog qee qhov piv txwv. Piv txwv 1 Tossing ib npib
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
