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

## Step 1The given equation is . This equation is not balanced because the number of atoms of each element is not the same on both sides of the equation.## Step 2To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. ## Step 3Looking at the equation, we can see that there are 2 hydrogen atoms on the left side (in ) and 2 hydrogen atoms on the right side (in ). However, there are 2 oxygen atoms on the left side (in ) and only 1 oxygen atom on the right side (in ).## Step 4To balance the oxygen atoms, we can multiply the on the right side by 2, giving us 4 hydrogen atoms on the right side. ## Step 5To balance the hydrogen atoms, we can multiply the on the left side by 2, giving us 4 hydrogen atoms on the left side. ## Step 6Now, the equation looks like this: . ## Step 7Finally, 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.
