Graph
Insert your graph here:

1. What is the equation for the linear trend-line for your equation?

Y=98.027x

2. What is the corrected equation for the trend-line?

Y=98.027x (wasn’t sure with this, I would assume it would already be okay
since the trend would suggest that the line passes through 0?)

Line Wavelength

1. What wavelengths are associated with the light color observed in each
metal’s flame test?

2. What are the most probable atoms in your unknown solid based on the
observed light emissions?

The unknown solid probably has sodium or something similar in it since the
light emissions look a lot like those from Sodium Chloride. The orange and red
emission lines suggest sodium or something close to it because its emission
spectrum closely matches Sodium Chloride’s spectrum.

3. Sodium light is easy to filter because it only emits light at a specific


wavelength. Would any of the other metals you tested also be easy to filter?
Why or why not?

Copper could also be easy to filter because it has clear blue and green lines.
It would be harder though because there are more lines.

4. If a fireworks engineer was planning a Christmas show and wanted to create


a red explosion followed by a green one. Based on the flames observed,
which metal salts should they use?

For a red explosion, Lithium Chloride and Copper Chloride a green explosion.
