Txog qhov no, puas yog carbon disulfide soluble hauv dej?
Carbon disulfide yog cov kua tsis muaj xim, nrog rau ib qho chloroform zoo li tsw thaum ntshiab. Tsis muaj CS2 muaj ib tug yellowish xim thiab muaj ib tug putrid tsw. Nws yog insoluble hauv dej, tab sis soluble nyob rau hauv ntau cov organic solvents, xws li benzene, ethanol, diethyl ether, carbon tetrachloride, chloroform . Nws tsis zoo soluble hauv formic acid.
Yuav ua li cas carbon disulfide tsim los ntawm carbon thiab Sulphur? Cov pa roj carbon disulfide yog tsim los ntawm cov tshuaj tiv thaiv ntawm carbon thiab sulfur . Cov pa roj carbon disulfide yog denser dua dej thiab tsuas yog me ntsis soluble hauv nws. Nws cov ntsiab lus kub yog 46.3 ° C (115.3 ° F) thiab nws qhov chaw khov -110.8 ° C (-169.2 ° F); nws vapour, uas hnyav dua huab cua, yog ignited nrog txawv txawv yooj yim.
Ib yam li ntawd, nws raug nug, hom ntawv cog lus twg yog carbon disulfide?
CS2 yog linear molecule nrog cov qauv uas muaj ob ob daim ntawv cog lus predominating tshaj cov uas muaj ib tug thiab ib tug triple daim ntawv cog lus.
Puas yog carbon disulfide ionic lossis covalent?
Cov pa roj carbon disulfide , kuj hu ua carbon bisulfide, yog ib qho tshuaj lom neeg. Nws muaj carbon thiab sulfide ions . Nws muaj carbon nyob rau hauv nws +4 oxidation xeev thiab sulfur nyob rau hauv nws -2 oxidation xeev.

Puas yog metallic bonds yaj hauv dej?
Cov hlau nplaum tsis soluble hauv dej vim tias: Lawv tau tuav ua ke los ntawm cov hlau nplaum muaj zog thiab yog li tsis muaj cov kuab tshuaj rau cov kuab tshuaj lom neeg tuaj yeem muaj zog dua li cov no, yog li cov tshuaj no tsis muaj dej txaus thiab lawv tsis muaj qhov tsim nyog intermolecular rog (xws li hydrogen bonds) uas muaj nyob hauv dej
Yuav ua li cas yog tag nrho yaj yaj nyob rau hauv lub pas dej ua ke?
Koj cov khoom tawg tag nrho, lossis TDS, tus nqi yog qhov ntsuas ntawm tag nrho cov khoom uas yaj hauv koj lub pas dej. Cov pas dej da dej yuav tsum muaj qhov siab tshaj TDS tus nqi ntawm ib ncig ntawm 1,500 txog 2,000 ppm. Piv txwv li, cov dej haus tuaj yeem muaj qhov siab tshaj TDS tus nqi ntawm 500 ppm raws li EPA
Puas yog ntsev yaj hauv dej spontaneous?
Kev daws ntawm NaCl hauv dej muaj ntau qhov kev txiav txim tsawg dua li cov dej ntshiab thiab cov ntsev crystalline. Entropy nce txhua lub sij hawm ib tug solute dissolves nyob rau hauv ib tug hnyav. Txawm hais tias qhov hloov pauv enthalpy yog tus lej zoo, qhov kev sib cais yog tshwm sim vim hais tias Gibbs tsis muaj zog hloov pauv, G, yog qhov tsis zoo vim lub sij hawm entropy
Puas yog cov kua qaub tsim hydronium ions thaum lawv yaj hauv dej?
Cov kua qaub yog ib qho sib xyaw uas yaj hauv dej los ua ib hom kev daws teeb meem. Chemically, cov kua qaub yog ib yam khoom uas tsim hydronium ions (H3O +) thaum yaj hauv dej. Thaum hydrochloric acid (HCl) yaj nyob rau hauv dej, nws ionizes, splitting mus rau hauv hydrogen (H +) thiab chlorine (Cl-) ions
Puas yog aragonite yaj hauv dej?
Cov kws tshawb fawb tshwj xeeb tshaj yog nyiam nyob rau hauv aragonite, uas yog tsim los ntawm ntau tropical corals, txias-dej coral, pteropods thiab ib co molluscs. Nws yog soluble ntau dua li calcite. Cov plhaub tsis muaj kev tiv thaiv thiab cov pob txha pob txha yaj thaum cov carbonate ions hauv dej tsis tshua muaj - nws tsis txaus los yog corrosive
