Dab tsi yog Chemical Formula thiab Molecular Luj ntawm Sodium Cyanide?

Sodium cyanide yog ib qho tshuaj uas muaj ob qho tib si rau kev siv hauv kev lag luam thiab kev nyab xeeb tseem ceeb vim nws muaj tshuaj lom heev. Hauv tsab xov xwm no, peb yuav teb cov lus nug feem ntau txog nws cov mis tshuaj thiab qhov hnyav molecular.

Dab tsi yog Chemical Formula ntawm Sodium Cyanide?

Cov mis tshuaj ntawm sodium cyanide yog NaCN . Cov mis no yog los ntawm kev sib xyaw ua ke ntawm sodium (Na⁺) thiab cyanide ion (CN⁻). Sodium, ib hom hlau alkali, yooj yim pub ib lub electron kom ua tiav qhov kev teeb tsa electron ruaj khov, tsim ib lub ion uas muaj nqi zoo. Lub cyanide ion, ntawm qhov tod tes, muaj ib lub carbon atom triple - bonded rau ib lub nitrogen atom thiab nqa ib lub nqi tsis zoo. Thaum sodium thiab cyanide ions sib xyaw ua ke, lawv tsim ib lub ionic compound, Sodium Cyanide , nrog rau cov mis NaCN.

Qhov Molecular Luj ntawm Sodium Cyanide suav li cas?

Yuav kom xam tau qhov hnyav molecular (tseem hu ua molar mass ) ntawm Sodium cyanide , peb yuav tsum xav txog qhov hnyav atomic ntawm cov ntsiab lus uas ua rau cov tshuaj sib xyaw.

• Qhov hnyav atomic ntawm sodium (Na) yog kwv yees li 22.99 g / mol.

• Qhov hnyav atomic ntawm carbon (C) yog hais txog 12.01 g / mol.

• Qhov hnyav atomic ntawm nitrogen (N) yog nyob ib ncig ntawm 14.01 g / mol.

Rau sodium cyanide (NaCN), vim tias muaj ib qho sodium atom, ib qho carbon atom, thiab ib nitrogen atom hauv txhua chav tsev, qhov hnyav molecular yog xam raws li hauv qab no:

Molecular Luj ntawm NaCN = (Atomic hnyav ntawm Na) + (Atomic hnyav ntawm C) + (Atomic hnyav ntawm N)

22.99 g / mol + 12.01 g / mol + 14.01 g / mol

= 49.01 g/mol

Yog li, qhov hnyav molecular ntawm sodium cyanide yog kwv yees li 49.01 g / mol.

Sodium cyanide, nrog rau nws cov qauv tshuaj tshwj xeeb thiab qhov hnyav molecular, yog siv dav hauv ntau qhov kev lag luam, xws li kub mining rau rho tawm kub los ntawm nws cov ore los ntawm cov txheej txheem hu ua cyanidation. Txawm li cas los xij, vim nws cov tshuaj lom heev, kev tuav kom zoo thiab cov txheej txheem kev nyab xeeb nruj yuav tsum tau ua thaum cuam tshuam nrog qhov sib xyaw no. Nkag siab txog nws cov khoom siv tshuaj, suav nrog cov qauv thiab qhov hnyav molecular, yog qhov tseem ceeb rau ob qho tib si kev lag luam thiab kev tswj hwm kev nyab xeeb.
