Magnesium oxide yog siv ua kom kub-resistant cib rau qhov cub thiab qhov cub. Magnesium hydroxide (mis nyuj ntawm magnesia), sulfate (Epsom ntsev), chloride thiab citrate yog tag nrho. siv hauv tshuaj. Grignard reagents yog cov organic magnesium compounds uas tseem ceeb rau cov tshuaj kev lag luam.
Xav txog qhov no, Magnesium puas tuaj yeem sib cais los ntawm kev siv tshuaj?
Lwm qhov kev xaiv yog cov khoom sib xyaw. Cov ntsiab lus ua tau ua tawg rau hauv cov khoom siv yooj yim. Magnesium Methanol yog qhov sib xyaw ua ke ntawm carbon, hydrogen, thiab oxygen. Cov tshuaj ua tau ua tawg nyob rau hauv lawv cov componenets los ntawm tshuaj txhais tau tias.
Tom qab, lo lus nug yog, dab tsi yog cov xim ntawm magnesium? Hauv cov xwm txheej txheem magnesium yog lub teeb hlau nrog a nyiaj - dawb xim. Thaum raug huab cua, magnesium yuav tarnish thiab tiv thaiv los ntawm ib tug nyias txheej ntawm oxide. Thaum nkag mus rau hauv dej, magnesium yuav hnov mob thiab tsim cov roj hydrogen. Yog tias submerged hauv dej, koj yuav pom cov pa roj npuas pib tsim.
Ntawm no, dab tsi yog ua los ntawm magnesium?
Lub koob yees duab, horseshoes, baseball catchers 'qhov ncauj qhov ntswg thiab snowshoes yog lwm yam khoom uas yog ua los ntawm magnesium alloys. Magnesium oxide (MgO), tseem hu ua magnesia, yog qhov thib ob ntau tshaj plaws nyob rau hauv lub ntiaj teb crust.
Dab tsi yog 3 yam tshuaj ntawm magnesium?
Cov khoom siv tshuaj ntawm Magnesium yog raws li hauv qab no:
- Cov tshuaj formula: Mg.
- Cov khoom xyaw: Oxide, hydroxide, chloride, carbonate thiab sulfate.
- Flammability: Hlawv hauv huab cua nrog lub teeb dawb ci.
- Reactivity: Thaum cua sov, magnesium reacts nrog halogens los tawm halides.
- Alloys: Magnesium alloys yog lub teeb, tab sis muaj zog heev.

Lub npe rau ib yam khoom tsim nyob rau hauv cov tshuaj tiv thaiv tshuaj yog dab tsi?
Cov tshuaj tiv thaiv tshuaj yog cov txheej txheem uas cov atoms tam sim no nyob rau hauv cov tshuaj pib rov ua kom muab cov tshuaj sib xyaw tshiab tam sim no hauv cov tshuaj tsim los ntawm cov tshuaj tiv thaiv. Cov tshuaj pib ntawm cov tshuaj tiv thaiv tshuaj hu ua reactants, thiab cov tshuaj tshiab uas tshwm sim hu ua cov khoom

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 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
