Sodium cyanide ndi mankhwala omwe amagwiritsidwa ntchito m'mafakitale komanso otetezeka chifukwa cha poizoni wake wambiri. M'nkhaniyi, tiyankha mafunso omwe amafunsidwa kawirikawiri okhudza njira yake ya mankhwala ndi kulemera kwa mamolekyu.
Kodi Chemical Formula ya Sodium Cyanide ndi chiyani?
Fomula ya mankhwala ya sodium cyanide ndi NaCN . Fomula iyi imachokera ku kuphatikiza kwa sodium (Na⁺) ndi ion ya cyanide (CN⁻). Sodium, chitsulo cha alkali, imapereka mosavuta electron imodzi kuti ikwaniritse mawonekedwe okhazikika a electron, ndikupanga ion yokhala ndi positive charge. Komano, ion ya cyanide imakhala ndi atomu ya carbon katatu - yolumikizidwa ku atomu ya nayitrogeni ndipo imakhala ndi charge yoyipa. Pamene ma ayoni a sodium ndi cyanide aphatikizana, amapanga compound ya ionic, Sodium Cyanide , yokhala ndi fomula ya NaCN.
Kodi Molecular Weight ya Sodium Cyanide imawerengedwa bwanji?
Kuti tiwerenge kulemera kwa molekyulu (komwe kumatchedwanso molar mass ) ya Sodium cyanide , tiyenera kuganizira kulemera kwa atomiki kwa zinthu zomwe zimapanga chophatikizacho.
Kulemera kwa atomiki ya sodium (Na) ndi pafupifupi 22.99 g/mol.
Kulemera kwa atomiki ya carbon (C) ndi pafupifupi 12.01 g/mol.
Kulemera kwa atomiki kwa nayitrogeni (N) ndi pafupifupi 14.01 g/mol.
Kwa sodium cyanide (NaCN), popeza pali atomu imodzi ya sodium, atomu imodzi ya carbon, ndi atomu imodzi ya nayitrogeni mumtundu uliwonse wa formula, kulemera kwa maselo kumawerengedwa motere:
Kulemera kwa molekyulu ya NaCN = (Kulemera kwa Atomiki kwa Na) + (Kulemera kwa Atomiki C) + (Kulemera kwa Atomiki kwa N)
= 22.99 g/mol + 12.01 g/mol + 14.01 g/mol
= 49.01 g/mol
Choncho, kulemera kwa molekyulu ya sodium cyanide ndi pafupifupi 49.01 g/mol.
Sodium cyanide, yokhala ndi mawonekedwe ake enieni komanso kulemera kwake kwa mamolekyulu, imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, monga migodi ya golide pochotsa golide ku miyala yake kudzera munjira yotchedwa cyanidation. Komabe, chifukwa cha kawopsedwe kake, kugwiritsiridwa ntchito koyenera ndi ndondomeko zotetezedwa zimafunikira pochita ndi mankhwalawa. Kumvetsetsa za mankhwala ake, kuphatikizapo chilinganizo ndi kulemera kwa maselo, n'kofunika kwambiri pa ntchito za mafakitale ndi kasamalidwe ka chitetezo.
