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.
