Calcium cyanide kuj hu ua dub cyanide , yog ib qho inorganic compound nrog cov mis Ca (CN)₂. Nws yog cov khoom dawb, txawm tias nws tsis tshua pom nyob hauv daim ntawv ntshiab.

Calcium cyanide.

Cov npe
tsw	hydrogen cyanide
Qhov ntom	1.853 (20 ° C)
Melting point	640 ° C (1, 184 ° F; 913 K) (decomposes)
Solubility hauv dej	soluble

Ntawm no, yog calcium cyanide soluble hauv dej?

Cov ntsev ntawm sodium, poov tshuaj thiab calcium cyanide yog cov tshuaj lom heev, vim tias lawv yog cov soluble hauv dej, thiab yog li yooj yim yaj los ua dawb cyanide. Kev ua haujlwm feem ntau tau txais cyanide ua khoom lossis yaj NaCN lossis Ca(CN)₂.

cyanide puas tuaj yeem nyob hauv dej? Ib txhia cyanide hauv dej yuav hloov mus rau hauv cov tshuaj phem tsawg los ntawm cov kab mob (cov nroj tsuag thiab tsiaj me me), los yog yuav tsim ib tug complex nrog hlau, xws li hlau. Ib nrab-lub neej ntawm cyanide hauv dej tsis paub. Cyanide hauv dej ua tsis tsim nyob rau hauv lub cev ntawm ntses. Cyanides yog haum mobile hauv av.

Yog li, calcium cyanide siv rau dab tsi?

Calcium Cyanide yog cov hmoov dawb nrog cov ntxhiab tsw zoo li almond. Nws yog siv hauv stainless hlau manufacturing, leaching ores, raws li ib tug fumigant, tshuaj tua kab thiab ib koob tshuaj lom.

Puas yog cyanide acidic lossis yooj yim?

Hydrogen cyanide yog qaug zog acidic nrog pk_a ua 9.2. Nws ib nrab ionizes nyob rau hauv dej tov muab cov cyanide ib, CN⁻. Ib qho kev daws ntawm hydrogen cyanide Hauv dej, sawv cev ua HCN, hu ua hydrocyanic kua qaub . Cov ntsev ntawm cov cyanide anion yog hu ua cyanide.

Puas yog calcium cyanide yog cov kua qaub lossis lub hauv paus?

Calcium cyanide decomposes rau tsis tshua muaj tshuaj lom thiab flammable hydrogen cyanide thiab tshuaj lom thiab irritating nitrogen oxides thaum rhuab hauv hluav taws. QHOV 9. Lub cev thiab tshuaj lom neeg. Lub cev lub cev: Lub hauv paus ruaj khov: Reacts maj mam nrog dej los tsim calcium hydroxide, uas yog lub hauv paus muaj zog

Thaum koj kub calcium carbonate ib qho khoom dawb nrog cov mis CaCO3 nws tawg los ua cov khoom calcium oxide CaO thiab carbon dioxide gas co2?

Thaum tshav kub kub tshaj 840 ° C, calcium carbonate decomposes, tso cov pa roj carbon dioxide thiab tawm hauv qab calcium oxide - cov khoom dawb. Calcium oxide hu ua txiv qaub thiab yog ib qho ntawm 10 cov tshuaj uas tsim tawm txhua xyoo los ntawm thermal decomposition ntawm limestone

Cov tshuaj tiv thaiv dab tsi yog calcium carbonate calcium oxide carbon dioxide?

Calcium carbonate tau kub siab kom txog thaum nws dhau los ua thermal decomposition los tsim calcium oxide thiab carbon dioxide. Cov calcium oxide (unslaked txiv qaub) yog yaj hauv dej los tsim calcium hydroxide (limewater). Bubbling carbon dioxide los ntawm qhov no ua ib qho kev ncua ntawm calcium carbonate

Dab tsi yog qhov sib npaug ionic rau cov tshuaj tiv thaiv ntawm aqueous lead II nitrate nrog aqueous sodium bromide?

Cov tshuaj tiv thaiv ntawm aqueous sodium bromide thiab aqueous lead (II) nitrate yog sawv cev los ntawm qhov sib npaug net ionic equation. 2Br−(aq)+Pb2+(aq) →PbBr2(s) 2 B r − (a q) + P b 2 + (a q) → P b B r 2 (s)
