![The flame from the burning sulfur is very faint and a bit hard to see in regular air, so the video shows the
burning compound being lowered into a container full of oxygen gas. To understand why this helps the
flame glow brighter, it is helpful to look at the chemical reaction for burning sulfur. When a substance
burns in air it is essentially reacting with the oxygen in the air according to the equation shown below:
S(s) + O2(g) SO2(g) + heat
The air contains only about 21% oxygen so the reaction happens with only 21% of the molecules in the
air. When you lower the sulfur into a container of pure oxygen the reaction happens with 100% of the
molecules and so the reaction happens on a larger scale and more quickly - resultingin the emission of
much more light!

Let's revisit the visible portion of the electromagnetic spectrum we showed in the Background. Think
about all the different color flames you saw in this experiment and try to place the colors at a specific
point on the color spectrum shown here.
When you are ready make a data table that includes all eight substances tested, the color of their emitted
photons (essentially their flame), and the approximate wavelength of that color. Order your table with the
purple end of the spectrum on the top and the red end of the spectrum at the bottom.
