Explanation:
Detailed explanation-1: -This is a decomposition reaction.
Detailed explanation-2: -2Al(OH)₃→Al₂O₃+3H₂O The above reaction is an Endothermic reaction, which involves breaking down of aluminium hydroxide into its oxide and give out water as by-product.
Detailed explanation-3: -In the given reaction, 2Al2O3(s)→4Al(s)+3O2(g)H=+3352kJ/mol. 2 A l 2 O 3 ( s ) → 4 A l ( s ) + 3 O 2 ( g ) H = + 3352 k J / m o l . This indicates that the decomposition of Al2O3 A l 2 O 3 is endothermic.
Detailed explanation-4: -Here, there are two reactants (Al and O2) combining to form one product, Al2O3, so this is a synthesis reaction.
