Investigation 7 Test Balance the following equation. square H_(2)+square O_(2)arrow square H_(2)O

## Step 1<br />The given equation is \(H_{2} + O_{2} \rightarrow H_{2}O\). This equation is not balanced because the number of atoms of each element is not the same on both sides of the equation.<br /><br />## Step 2<br />To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. <br /><br />## Step 3<br />Looking at the equation, we can see that there are 2 hydrogen atoms on the left side (in \(H_{2}\)) and 2 hydrogen atoms on the right side (in \(H_{2}O\)). However, there are 2 oxygen atoms on the left side (in \(O_{2}\)) and only 1 oxygen atom on the right side (in \(H_{2}O\)).<br /><br />## Step 4<br />To balance the oxygen atoms, we can multiply the \(H_{2}O\) on the right side by 2, giving us 4 hydrogen atoms on the right side. <br /><br />## Step 5<br />To balance the hydrogen atoms, we can multiply the \(H_{2}\) on the left side by 2, giving us 4 hydrogen atoms on the left side. <br /><br />## Step 6<br />Now, the equation looks like this: \(2H_{2} + O_{2} \rightarrow 2H_{2}O\). <br /><br />## Step 7<br />Finally, we check the equation to ensure that the number of atoms of each element is the same on both sides of the equation. We find that there are 4 hydrogen atoms and 2 oxygen atoms on both sides of the equation, which means the equation is now balanced.
