Solution

Aluminum Oxide( $A l_{2} O_{3}$ ) or Alumina is obtained by heating Aluminum hydroxide( $A l {(O H)}_{3}$ ).
The temperature given for this reaction is $1100 ° C$ .
The equation for this reaction is,
$\underset{A l u m i n u m h y d r o x i d e}{2 A l {(O H)}_{3} (a q)} \overset{∆}{\to} \underset{A l u m i n a}{A l_{2} O_{3} (s)} + 3 H_{2} O (l)$ .
