2 The Atom Inventory Process In this class we will always use a process called an atom inventory (AI) to balance an equation. Step 1: List the elements in the equation under the unbalanced equation in an atom inventory chart. Here’s how it works.

35 One last tip for balancing equations that contain atmospheric oxygen: O 2 (g). Often you will reach a point where the number of oxygen atoms on one side of the equation is an odd number and the number of oxygen atoms on the other side is an even number. The quick solution is to go through the entire equation and multiply all the coefficients by 2—except the one in front of atmospheric oxygen (O 2 ). You can then recalculate the number of atoms and determining the number of oxygen atoms that are needed and enter the correct coefficient.
