3.What is the connection between the flame tests in Activity 1 and fireworks? List 4 metalsused in fireworks and state the color they produce.The flame tests in Activity 1 and fireworks relate to each other becauseflame tests are used to demonstratehow an element’s valence electronsreact to heat. Similarly, fireworks involve elements being explosively lit offbecause they are in contact with heat. Elemental contact with heat, inboth the flame tests and fireworks, shows the colors produced by theseelements. Some that are used in fireworks include: Barium Chloride(BaCI2)Yellow-green flame; Lithium Chloride (LiCi)Red flame; SodiumChloride (NaCI)Yellow flame; Copper Chloride (CuCI2)Green flame.Data and ObservationsRecord all data using the significant figures allowed by the measuring device. Calculate eachrequested result, showingALL CALCULATIONSand reporting each result with the correctnumber of significant figures and units.Activity 1:The Emission Spectra of Metal Salts
