: 中国大陆电视剧《颜心记》的大结局是什么 ://en.wikipedia.org/wiki/Cyanide Cadmium cyanamide is a chemical compound with the formula Cd(NH2)₂. It was used in agriculture as fertilizer and for producing other cadmium compounds. It can be produced by reacting ammonia (NH3), hydrogen, or nitrogen gas under high pressure at elevated temperatures: CdO + 4 NH₃ → HCN(气态氰化钠)+ N_{}^{}_8+ CH₄(gas) or \[ \text{6}[\ce{{\mathrm{(s)}}]_{}}+\frac{\left(\right)}{{{1}}}N_\infty^{0}\rightarrow [\begin'text{textstyle C}}{{d({t}{e{x}_{x})}_{}\times }}[c]{n\times }[{h}]_(g)\] The reaction of solid sodium nitride (\chemNa³⁺\(a\)²¹))with water produces gaseous hydrocyanic acid which reacts further to produce liquid ammoniacal solution containing some dissolved carbon dioxide. This process has been commercialized on an industrial scale since it's more efficient than traditional methods such like using potassium ferrocynanid.
