Dab tsi ntawm pawg pob zeb hauv qab no, yog tias muaj cov silicon: carbonates, halides, lossis sulfides? tsis muaj. Carbonates, halides thiab sulfides yog tag nrho cov nonsilicates.
YPuas carbonates muaj silicon?
Silicates muaj silicon atom ncig los ntawm plaub lub atoms oxygen. Quartz (silicon dioxide, SiO2) yog ib hom silicate. Carbonates muaj cov pa roj carbon atom ncig los ntawm peb cov pa oxygen. Calcite (calcium carbonate, CaCO3) yog ib qho carbonate uas muaj nyob hauv limestones.
Yuav ua li cas cov zaub mov muaj silicon?
Silicon yeej tsis pom nyob hauv nws lub xeev ntuj, tab sis theej ua ke nrog oxygen raws li silicate ion SiO44 - hauv cov pob zeb uas muaj silica xws li obsidian, granite, diorite, thiab sandstone Feldspar thiab quartz yog cov ntxhia silicate tseem ceeb tshaj plaws.
Yog halides minerals?
Halide minerals yog s alts. Lawv tsim thaum dej ntsev evaporates. Cov chav kawm ntxhia no suav nrog ntau dua li cov lus ntsev xwb. Halide minerals yuav muaj cov ntsiab lus fluorine, chlorine, bromine, los yog iodine.
Qhov twg ntawm ob pawg tseem ceeb ntawm cov zaub mov muaj ntau dua hauv lub ntiaj teb crust?
Qhov kwv yees li 1,000 silicate minerals ua ntau dua 90% ntawm lub ntiaj teb crust. Silicates yog nyob deb ntawm pawg pob zeb loj tshaj plaws. Feldspar thiab quartz yog ob qho tib si silicate minerals. Ob qho tib si yog cov pob zeb ua pob zeb ntau heev.

Puas yog halides ua kom ua haujlwm lossis tsis ua haujlwm?
Halogens yog electronegative heev. Qhov no txhais tau hais tias inductively lawv yog electron rho tawmTxawm li cas los xij, vim lawv muaj peev xwm pub dawb ib leeg ntawm electrons hauv cov ntawv resonance, lawv yog activators thiab ortho / para directing.
Puas yog alkyl halides soluble hauv dej?
Alkyl halides muaj me ntsis kom tsis muaj solubility hauv dej txawm tias muaj cov pa roj carbon-halogen daim ntawv cog lus. Lub attraction ntawm alkyl halide molecules muaj zog tshaj qhov attraction ntawm alkyl halide thiab dej. Alkyl halides muaj me ntsis tsis muaj solubility hauv dej, tab sis yuav tsum paub txog qhov ntom ntom .
Puas yog alkyl halides dej soluble?
Alkyl halides muaj me ntsis rau tsis muaj solubility nyob rau hauv dej txawm tias muaj polar carbon-halogen daim ntawv cog lus. Lub attraction ntawm alkyl halide molecules muaj zog tshaj qhov attraction ntawm alkyl halide thiab dej. Alkyl halides muaj me ntsis tsis muaj solubility hauv dej, tab sis yuav tsum paub txog qhov ntom ntom .
Puas yog cov neeg saib xyuas muaj koob muaj npe muaj ntawv hla tebchaws?
Diplomatic passport thiab tus neeg sawv cev ntawm tus neeg sawv cev Lub peev xwm kom tau txais daim ntawv hla tebchaws diplomatic lossis teem caij ua tus neeg sawv cev ntawm tus neeg sawv cev yog qhov kev hwm uas tau tshwj tseg rau ob peb xaiv.
Puas muaj silicon raws li lub neej?
Yog li, cov lus teb, tsawg kawg rau tam sim no, tsis yog - txawm hais tias silicon qee zaum siv tau los ua cov txheej txheem kev txhawb nqa (thiab muaj qee qhov piv txwv thov silicon ua ib qho tseem ceeb hauv kab) rau carbon-based life - silicon- raws li lub neej nws tus kheej tsis muaj nyob, raws li peb paub, vim muaj tshuaj thiab … Lub neej ua silicon puas muaj nyob hauv lub qab ntuj khwb?
