Vedclass · Answer

(C) The given equation represents the extraction of gold $(Au)$ or silver $(Ag)$ from their native ores using cyanide solution,a process known as Mac-Arthur-Forrest cyanide process.The balanced chemical equation for the extraction of gold is:$4Au + 8CN^- + 2H_2O + O_2 \xrightarrow{} 4[Au(CN)_2]^- + 4OH^-$Here,the metal $M$ is $Au$ (Gold).

In the equation,the metal $M$ is:
$4M + 8CN^- + 2H_2O + O_2 \xrightarrow{} 4[M(CN)_2]^- + 4OH^-$
