The left side of the equation contains \(2\text{Al}(\text{OH})_3\) and \(3\text{H}_2\text{SO}_4\). Each aluminum hydroxide has 3 oxygen atoms and there are 2 molecules, so that makes 6 oxygen atoms. Each sulfuric acid has 4 oxygens and there are 3 molecules, so that makes 12 oxygen atoms. Therefore, in total, there are 18 oxygen atoms on the left side of the equation.
How many oxygen atoms are on the left side of the equation below?
\(2\text{Al(OH)}_3 + 3\text{H}_2\text{SO}_4 \rightarrow \text{Al}_2(\text{SO}_4)_3 + 6\text{H}_2\text{O}\)
