## Step 1The problem asks us to identify the correct chemical equation that represents the given word description. The word description is "Aluminum and Oxygen gas yields Aluminum oxide". This means that Aluminum (Al) and Oxygen gas (O2) react to form Aluminum oxide (Al2O3).## Step 2We need to balance the chemical equation. This means that the number of atoms of each element must be the same on both sides of the equation. ## Step 3Looking at the options, we can see that option B, "4Al + 3O2 → 2Al2O3", is the correctly balanced equation. This is because there are 4 Aluminum atoms and 6 Oxygen atoms on both sides of the equation.
