Goal: the reorganization of atoms in chemical reactions results in the release or absorption of heat energy.
Chemical formula: Name of Metal: Color Produced:
KNO3 K peach color
Sr (NO3) Sr orange red
BaCNo3 Ba yellow
CuCl2 Cu lime green
DEW D Yellow, and green sparks.
LiNO3 Li red
CoCl3 Co yellow
In this lab we learned what metals change the color of a flame when it is put in the flame.
the flame color changed is what a chemical reaction is, when a metal mixes with flame it will change colors depending on what metal it is. My favorite metal to put into the flame was the Sr (NO3) because the color of the flame was orange red. it was a bright color.
