Question

What is the objective of the experiment described in the text?

I - Analyze the color of the flame related to the presence of metallic chemical elements in some salts.
II - Identify the metallic chemical elements present in some salts based on the color emitted by the flame.
III - Analyze the phenomenon of luminous emission by excitation and its relation to Bohr's atomic model.
IV - Identify regions of the electromagnetic spectrum, use the Bunsen burner correctly, and characterize the zones of the flame produced by this equipment.
a) Only I and II are correct.
b) Only III and IV are correct.
c) I, II, III, and IV are correct.

Ed · Answer
