• Copper (i) Chloride and Copper (ii) Chloride have same color Blue/Green. It is because both contains Chloride and that’s might be the reason of having same color.
• Potassium Chloride and Potassium Carbonate have same color Baby pink. It is because both contains Potassium in it and that’s might the reason of having same color.
• Strontium Nitrate, Strontium Chloride and lithium Chloride have same color Red. It is because Strontium Nitrate and Strontium Chloride contains Strontium in it and Strontium Chloride and lithium Chloride contains Chloride in it. Strontium and Chloride might be the reason of having same color.
• Sodium Bicarbonate and Sodium Chloride have same color Orange. It is because both contains Sodium in it and that’s might

They both produces orange color. The color of the flame help in determining the compound.
Unknow #2 is Sodium Chloride because they have almost same color flame. They both produces orange color. The color of the flame help in determining the compound.
Unknow #3 is Strontium chloride because they have almost same color flame. They both produces red color. The color of the flame help in determining the compound.
Unknow #4 is Lithium chloride because they have almost same color flame. They both produces red color. The color of the flame help in determining the compound.
Reasoning:
The Flames test lab shows how different compounds react to heat and energy. After testing all compounds we were able to find out the unknown compounds. The unknown#1 is Sodium Bicarbonate is because they both produces the flame of same color. The unknown#2 is Sodium Chloride because both produces same color flame. The unknown#3 is Strontium chloride because they produces the flame of same color. The unknow #4 is Lithium chloride because they both produce same color flame.
4 The different color of the flame happens because of the electrons are in different energy
