Ceramic square : Siv kom tsis txhob hlawv qhov chaw ntawm koj lub chaw kuaj sim thiab ua rau koj chemistry xib hwb npau taws. Clamps: Siv tuav ntau yam khoom nyob rau hauv qhov chaw, tshwj xeeb tshaj yog cov hlab ntsha. Av nplaum daim duab peb sab: Siv tuav lub crucible thaum nws yog rhuab.
Ntawm no, dab tsi cov cuab yeej siv hauv chemistry?
Beakers . Erlenmeyer khob , AKA conical flasks. Florence flasks, AKA boiling flasks. Test tubes, ntiv tes, thiab racks.
Tsis tas li ntawd, cov cuab yeej twg yog qhov zoo tshaj plaws rau cua sov cov kua dej tsis haum? Bunsen burner yog cov pa thiab txhais tau tias yooj yim rau cua sov ntawm kua nyob rau hauv cov hlab ntsha thiab cov beakers me me. Txawm li cas los xij, cov nplaim liab qab tuaj yeem ua rau hluav taws kub thiab tawg yog tias muaj li ntawd cua sov yog nqa tawm nyob rau hauv ze ze ntawm flammable kua los yog cov khoom tawg.
Hauv qhov no, dab tsi yog Scoopula siv rau hauv chemistry?
Scoopula yog ib lub npe ntawm cov khoom siv spatula zoo li rab diav siv feem ntau hauv chemistry Cov chaw kuaj mob kom hloov cov khib nyiab: mus rau ib daim ntawv hnyav rau qhov hnyav, mus rau lub hau npog los ntsuas qhov melting point, los yog ib lub tog raj kheej kawm tiav, los yog mus rau lub iav saib los ntawm lub hwj los yog beaker los ntawm scraping.
Laboratory apparatus yog dab tsi?
Laboratory apparatus yog cov cuab yeej siv thiab cov khoom siv ntau tshaj plaws uas koj xav tau thaum ua haujlwm ntawm tes hauv a chav kuaj . Cov Laboratory apparatus nyob ntawm hom chav kuaj koj nyob hauv thiab qhov kev sim koj yuav ua.

Dab tsi yog qhov txawv ntawm cov chemistry thiab organic chemistry?
Organic chemistry yog suav tias yog ib qho kev qhia ntawm chemistry. Thaum lub sij hawm lub kaus dav dav 'chemistry' yog kev txhawj xeeb nrog kev sib xyaw thiab kev hloov pauv ntawm txhua yam teeb meem, cov khoom siv tshuaj lom neeg tsuas yog txwv rau kev kawm ntawm cov organic tebchaw xwb
Puas yog cement yog cov khoom siv ceramic?
Cov tsoos ceramics suav nrog cov khoom siv av nplaum, silicate iav thiab cement; Thaum cov ceramics siab heev muaj carbides (SiC), ntshiab oxides (Al2O3), nitrides (Si3N4), non-silicate iav thiab ntau lwm yam. Cov ntaub ntawv ceramic tso saib ntau yam khoom uas pab txhawb lawv siv hauv ntau qhov chaw sib txawv
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog carbon nyob rau hauv chemistry?
Organic molecules muaj ob qho tib si carbon thiab hydrogen. Txawm hais tias ntau cov tshuaj organic kuj muaj lwm cov ntsiab lus, nws yog carbon-hydrogen daim ntawv cog lus uas txhais tau tias lawv yog cov organic. Organic chemistry txhais lub neej. Kev sib txawv ntawm cov tshuaj organic yog vim muaj ntau yam ntawm carbon atom
