Cool experiment: Red Phosphorus and Bromine

Red Phosphorus and Bromine

The chemical equation for this is 4P + 5O2 - P4O10. I knew this was a chemical reaction because it changed colors.
Aluminium and Iodine reaction

Aluminum and Iodine

The chemical equation for this is 2Al + 3I2 → Al2I6. I knew this was a chemical reaction because it produces iodine vapor and it changes color.
How to make Fireflies

Chromium and Oxide

The chemical equation for this is Cr2O3 + 3 CrO3 → 5 CrO2 + O2. I knew this was a chemical reaction because it changed state and color.
