I-sodium cyanide yikhompawundi enezicelo zoshishino kunye nemiphumo ebalulekileyo yokhuseleko ngenxa yobuthi bayo obuphezulu. Kweli nqaku, siza kuphendula imibuzo eqhelekileyo malunga nefomyula yayo yeekhemikhali kunye nobunzima bemolekyuli.
Yintoni iFomula yeMichiza yeSodium Cyanide?
Ifomula yekhemikhali ye - sodium cyanide yiNaCN . Le fomula ithathwe kudibaniso lwe-sodium (Na⁺) kunye ne-cyanide ion (CN⁻). I-Sodium, isinyithi se-alkali, inikela ngokulula nge-electron enye ukuze ifikelele kwisimo esizinzileyo se-electron, yenze i-ion etshajiweyo kakuhle. I-ion ye-cyanide, kwelinye icala, ine-atom yekhabhoni ephindwe kathathu - ebotshelelwe kwi-atom ye-nitrogen kwaye ithwala itshaja engalunganga. Xa ii-ion ze-sodium kunye ne-cyanide zidityanisiwe, zenza i-ionic compound, iSodium Cyanide , kunye ne-formula yeNaCN.
Bubalwa njani ubunzima beMolekyuli yeSodium Cyanide?
Ukuze sibale ubunzima bemolekyuli (ekwaziwa ngokuba yi -molar mass ) yeSodium cyanide , kufuneka siqwalasele ubunzima beathomu yezinto ezenza le compound.
Ubunzima be-athomu ye-sodium (Na) malunga ne-22.99 g / mol.
Ubunzima be-athomu yekhabhoni (C) bumalunga ne-12.01 g/mol.
Ubunzima beathom yenitrogen (N) bujikeleze i-14.01 g/mol.
Kwi-sodium cyanide (NaCN), ekubeni kukho i-athomu yesodium enye, i-athomu yekhabhoni enye, kunye ne-athomu enye yenitrogen kwiyunithi nganye yefomula, ubunzima bemolekyuli bubalwa ngolu hlobo lulandelayo:
Ubunzima be-Molecular of NaCN = (Ubunzima be-Atomic ye-Na) + (Ubunzima be-Atomic ye-C) + (Ubunzima be-Atomic ye-N)
= 22.99 g/mol + 12.01 g/mol + 14.01 g/mol
= 49.01 g/mol
Ngoko ke, ubunzima bemolekyuli yesodium cyanide bumalunga ne- 49.01 g/mol.
Isodium cyanide, kunye nefomula yayo ethile yeekhemikhali kunye nobunzima bemolekyuli, isetyenziswa kakhulu kumashishini ahlukeneyo, afana nokwembiwa kwegolide ukukhupha igolide kwiintsimbi zayo ngenkqubo ebizwa ngokuba yicyanidation. Nangona kunjalo, ngenxa yobutyhefu obugqithisileyo, ukuphathwa ngokufanelekileyo kunye neeprothokholi ezingqongqo zokhuseleko ziyafuneka xa ujongene nale khompawundi. Ukuqonda iimpawu zayo zeekhemikhali, kubandakanywa nefomula kunye nobunzima bemolekyuli, kubalulekile kuzo zombini izicelo zamashishini kunye nolawulo lokhuseleko.
