Cov ntsiab lus ntawm carbon yog cais raws li cov organic thaum cov pa roj carbon khi rau hydrogen. Carbon compounds xws li carbides (piv txwv li, silicon carbide [SiC2]), qee cov carbonates (piv txwv li, calcium carbonate [CaCO3]), qee qhov cyanides (piv txwv li, sodium cyanide [NaCN]), graphite, carbon dioxide, thiab carbon monoxide raug cais raws li inorganic.
Yuav ua li cas cov organic compound muaj?
Ntau cov organic tebchaw muaj carbon thiab hydrogen, tab sis lawv kuj tseem muaj lwm cov ntsiab lus (xws li nitrogen, oxygen, halogens, phosphorus, silicon, sulfur).
Yuav ua li cas cov organic tebchaw tsis muaj?
inorganic compounds yog cov organic tebchaw ib txwm muaj cov pa roj carbon thaum feem ntau cov tshuaj inorganic tsis muaj carbon. Tsis tas li ntawd, yuav luag tag nrho cov organic tebchaw muaj carbon-hydrogen lossis C-H bonds. Nco ntsoov tias muaj cov pa roj carbon tsis txaus rau qhov sib xyaw kom suav tias yog cov organic. Nrhiav ob qho tib si carbon thiab hydrogen.
Cov tshuaj dab tsi yog tsim los ntawm calcium?
Lwm cov ntsiab lus ntawm calcium suav nrog: calcium sulfate (CaSO 4), tseem hu ua gypsum, uas yog siv los ua kom qhuav. phab ntsa thiab plaster ntawm Paris, calcium nitrate (Ca(NO3)2), ib txwm muaj chiv thiab calcium phosphate (Ca 3(PO4)2), cov khoom tseem ceeb muaj nyob hauv cov pob txha thiab cov hniav.
Yuav ua li cas yog cov organic compounds feem ntau ua los ntawm?
Cov tebchaw organic feem ntau muaj pawg carbon atoms covalently bonded rau hydrogen, feem ntau yog oxygen, thiab feem ntau lwm yam zoo li. Tsim los ntawm cov khoom muaj sia, lawv pom thoob plaws ntiaj teb, hauv av thiab hiav txwv, cov khoom lag luam, thiab txhua lub cell ntawm tib neeg lub cev.

Puas tampons organic muaj cov khoom siv yas?
Organic tampons yog tsim los ntawm cov paj rwb organic, uas yog cog tsis siv tshuaj tua kab lossis chiv. Cov qauv uas tsis yog-organic feem ntau yog siv cov paj rwb thiab rayon sib xyaw. Ob txoj kev xaiv yog muaj cov ntawv thov yas, daim ntawv thov daim ntawv, lossis tsis muaj.
Puas cov ntsiav tshuaj calcium puas muaj kev phiv?
Calcium supplements ua rau ob peb, yog tias muaj, kev phiv. Tab sis qee zaum kev phiv tuaj yeem tshwm sim, suav nrog roj, cem quav thiab tsam plab. Feem ntau, calcium carbonate yog feem ntau cem quav. Tej zaum koj yuav tau sim ob peb lub npe sib txawv lossis hom tshuaj calcium kom pom ib qho uas koj zam qhov zoo tshaj plaws.
Puas fermentation yuav tsum muaj cov organic electron txais?
Fermentation siv ib qho organic molecule ua tus txais hluav taws xob zaum kawg los tsim NAD + los ntawm NADH kom glycolysis tuaj yeem txuas ntxiv. Fermentation tsis koom nrog kev thauj khoom hluav taws xob, thiab tsis muaj ATP yog tsim los ntawm cov txheej txheem fermentation ncaj qha.
Puas yog cov organic tebchaw volatile txaus ntshai?
Volatile organic compounds, lossis VOCs, yog cov pa roj uas tawm mus rau hauv huab cua los ntawm cov khoom lossis cov txheej txheem. Ib txhia ua mob rau lawv tus kheej, suav nrog qee yam ua rau mob qog noj ntshav. Tsis tas li ntawd, lawv tuaj yeem cuam tshuam nrog lwm cov pa roj thiab tsim lwm cov pa phem tom qab lawv nyob hauv huab cua.
Qhov twg ntawm cov tebchaw hauv qab no khaws cia hauv pyrenoids?
Starch, ib daim ntawv khaws cov piam thaj, feem ntau pom nyob ib ncig ntawm pyrenoids. Dab tsi yog khaws cia hauv pyrenoids? Feem ntau ntawm cov tswvcuab muaj ib lossis ntau lub cev cia hu ua pyrenoids nyob hauv chloroplasts. Pyrenoids muaj protein ntxiv rau cov hmoov txhuv nplej siab.
