Analyze the parts of the flow chart already filled. When solving chemistry flow charts, some of the information will already be in the chart. For example, you may be presented with a chart titled "From Solid to Gas." The flow chart has five vertical rectangles with one arrow under each box expect for the last box. The top rectangle says "Solid," the second rectangle is blank, the third rectangle says "Liquid," the fourth rectangle is blank and the fifth rectangle says "Gas."
Reach conclusions based on the information presented in the chemistry flow chart. Decide what the chart is about, and think logically about the process that the chart is trying to display. For example, the "From Solid to Gas" flow chart is displaying the transition from a solid to a gas. A solid needs to melt before it can become a liquid, then it must boil before it becomes a gas.
Fill in the missing information of the flow chart. After considering the process, you will have an easier time seeing which parts of the process are absent from the chart. For example, based on your analysis, you will put "Melting" in the second box, and "Boiling" in the fourth box.
Read all of the steps of the flow chart to ensure that it corresponds to the actual steps of the process. Determine whether or not the process makes sense. For example, your "From Solid to Gas" chemistry flow chart will read "Solid," "Melting," Liquid," "Boiling" and "Gas." Since the flow chart matches the actual process, your flow chart makes sense.
