2Al(OH)₃ → Al₂O₃ + 3H₂O

Answer 2

Chemical Reactions for Decomposition Upon Heating:

When certain chemical compounds are heated, they undergo decomposition reactions. Let's formulate the chemical equations for the decomposition of the following hydroxides upon heating:

a) Magnesium Hydroxide (Mg(OH)2): The decomposition of magnesium hydroxide upon heating can be represented by the following chemical equation: ``` Mg(OH)2(s) -> MgO(s) + H2O(g) ``` This equation shows that magnesium hydroxide decomposes into magnesium oxide and water vapor.

b) Iron(II) Hydroxide (Fe(OH)2): The decomposition of iron(II) hydroxide upon heating can be represented by the following chemical equation: ``` 2Fe(OH)2(s) -> 2FeO(s) + 2H2O(g) ``` This equation demonstrates that iron(II) hydroxide decomposes into iron(II) oxide and water vapor.

c) Aluminum Hydroxide (Al(OH)3): The decomposition of aluminum hydroxide upon heating can be represented by the following chemical equation: ``` Al(OH)3(s) -> Al2O3(s) + 3H2O(g) ``` This equation illustrates that aluminum hydroxide decomposes into aluminum oxide and water vapor.

These equations depict the decomposition reactions of the specified hydroxides when heated.
