The first Gizmo shows this equation: Fe + 3 CO 2 Fe + 3CO 2 O 3(s) (g)  (s) 2(g) There is a Question to solve under the equation. Here are the features that will help you solve each problem:  Y ou have a set of 16 tiles containing various conversion factors. Any of these tiles can be dragged down and placed on the green bar to solve the problem. The starting tile is already in place. It cannot be moved.  When you place a tile correctly , you will see a red line th...
