Q. Thermite process is used in reduction of
A) $C{rl}_{2}O_{3}$
B) $Al_{2}O_{3}$
C) $pbo_{2}$
D) $CuO$
Explanation
(a)
Oxides of less electropositive metals such as $Cr_{2}O_{3},$Mn etc are reduced by using Al. This process is called them process
$Cr_{2}O_{3} + 2Al \rightarrow Al_{2}O_{3} + 2Cr + Head$
