Answer

Al2O3\mathrm { Al } _ { 2 } \mathrm { O } _ { 3 }

Explanation

Solution

CH3CH2OH→350∘C⟶Al2CO3CH2=CH2+H2O\mathrm { CH } _ { 3 } \mathrm { CH } _ { 2 } \mathrm { OH } \xrightarrow [ 350 ^ { \circ } \mathrm { C } ] { \stackrel { \mathrm { Al } _ { 2 } \mathrm { CO } _ { 3 } } { \longrightarrow } } \mathrm { CH } _ { 2 } = \mathrm { CH } _ { 2 } + \mathrm { H } _ { 2 } \mathrm { O }
