The reaction between aluminum hydroxide (AI(OH)3) and sulfur trioxide (SO3) produces aluminum sulfate \((Al_2(SO_4)_3)\) and water. The balanced chemical equation for this reaction is:
\[ 2 Al(OH)_3 + 3 SO_3 \rightarrow Al_2(SO_4)_3 + 6 H_2O \]
In this reaction, two moles of aluminum hydroxide react with three moles of sulfur trioxide to produce one mole of aluminum sulfate and six moles of water.
