Solid aluminum hydroxide decomposes to produce solid aluminum oxide and water.

Question

how do i write this into a balanced chemical equation

Answer 1

Aluminum ions always exist in the +3 state in ionic compounds.

Al(OH)₃ breaks down into Al₂O₃ and water.

Al(OH)₃ → Al₂O₃ + H₂O

2Al(OH)₃ → Al₂O₃ + H₂O (balance aluminum)

2Al(OH)₃ → Al₂O₃ + 3H₂O (balance hydrogen and check equation is balanced)

Answer 2

These are the types of questions that provide opportunities for students to practice writing out balanced chemical equations vs. being given them

aluminum hydroxide ----------> aluminum oxide + water

First, write the chemical formulas

aluminum hydroxide __________

aluminum oxide __________

water __________

Then, replace the text in the chemical equation with the formulas

Then, balance ....
