Balancing Chemical Equations and Determining Reaction Types

To balance the given chemical equations and determine the types of reactions, let's analyze each equation one by one.

1. Al(OH)3 = Al2O3 + H2O

This equation represents the decomposition of aluminum hydroxide into aluminum oxide and water. To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides.

The balanced equation is:

2 Al(OH)3 = Al2O3 + 3 H2O

This is a decomposition reaction.

2. Fe2O3 + HCl = FeCl3 + H2O

This equation represents the reaction between iron(III) oxide and hydrochloric acid to form iron(III) chloride and water. Again, we need to balance the equation by adjusting the coefficients.

The balanced equation is:

Fe2O3 + 6 HCl = 2 FeCl3 + 3 H2O

This is a double displacement reaction.

3. N2 + H2 = NH3

This equation represents the reaction between nitrogen gas and hydrogen gas to form ammonia. Let's balance the equation:

N2 + 3 H2 = 2 NH3

This is a synthesis reaction.

4. Fe + Al2O3 = Al + Fe2O3

This equation represents the reaction between iron and aluminum oxide to form aluminum and iron(III) oxide. Balancing the equation:

2 Fe + Al2O3 = 2 Al + Fe2O3

This is a single displacement reaction.

In summary, the balanced equations and types of reactions are as follows:

1. Decomposition reaction: - Al(OH)3 = 2 Al2O3 + 3 H2O

2. Double displacement reaction: - Fe2O3 + 6 HCl = 2 FeCl3 + 3 H2O

3. Synthesis reaction: - N2 + 3 H2 = 2 NH3

4. Single displacement reaction: - 2 Fe + Al2O3 = 2 Al + Fe2O3
