1.) The liquids might fall into the burner. This causes the color to not be accurate.
2.) It was difficult to figure out, because the flame was the same color as another one.
3.) It is valid, because the flame could be the same color for more than one substance.
4.) By the different substances.
5.) Sr, Ba, Co, Cu, K
6.) I think that the chemicals have to be heated in the flame before the colored light comes out, because the flame would just stay the same and nothing would change.
