Chapter 7, Problem 7.86(choose chapter or problem)
In fireworks, the heat of the reaction of an oxidizing agent, such as KClO4, with an organic compound excites certain salts, which emit specific colors. Strontium salts have an intense emission at 641 nm, and barium salts have one at 493 nm. (a) What colors do these emissions produce? (b) What is the energy (in kJ) of these emissions for 5.00g each of the chloride salts of Sr and Ba? (Assume that all the heat produced is converted to emitted light.)
