In chemistry class, we studied basic Chemistry and we did some experiments in the class as well. One of the labs that we did was a flame lab. The objective of the lab is “To observe the relationship between various elements and their emission spectrum” We had the different compound of elements and we burn it in the flame. We observer and there some color when we burn each compound. The compound of the lab was Barium, Calcium, Copper, Lithium, Potassium, Strontium and the Unknown. We had the unknown there because our teacher wants us to figure out what it is.
Here is the data that I got from the lab I did:
I also had discussion questions and conclusion as well but, this is only the data of the color.

Barium Chloride | Yellow | 570 |
Calcium Chloride | Orange | 610 |
Copper (II) Chloride | Green | 612 |
Lithium Chloride | Red | 586 |
Potassium Chloride | Light red | 630 |
