Question

Identify $M$ and $N$ in the following reaction.
$Copperglance\stackrel{controlledheatinginpresenceofair}{\to }M+S{O}_2\uparrow$
$M\stackrel{N}{\to }Cu+S{O}_2\uparrow$
$M\stackrel{N}{\to }Cu+S{O}_2\uparrow$

• A. $M=C{u}_{2}O$; $N=$ self reduction
• B. $M=C{u}_{2}O+C{u}_{2}S$; $N=$ self reduction
• C. $M=C{u}_{2}O$; $N=$ carbon reduction
• D. $M=C{u}_{2}O$; $N=$ electrolytic reduction

Answer 1

The correct option is B $M=C{u}_{2}O+C{u}_{2}S$; $N=$ self reduction

$C{u}_{2}S+O_2\to \stackrel{c{u}_{2}O+c{u}_{2}S}{\leftarrow }+S{O}_2$

controlled m

$C{u}_{2}O\stackrel{C{u}_{2}S}{\to }cu+S{O}_2$

N

$M=C{u}_{2}O+C{u}_{2}S$

$N=$ self reduction
