1. Obtain about 3 inches of magnesium ribbon and observe the appearance of the solid. Write down your description of magnesium ribbon:
2. Using tongs, hold the end of the ribbon in the edge of a Bunsen burner flame until it ignites. DO NOT look directly at the flame. When the ribbon has finished oxidizing, describe the products on your lab bench.
3. The “word equation” for the chemical reaction you observed is “solid magnesium and oxygen combine to form dusty magnesium oxide.” Show the "skeleton equation" for the observed reaction (that means just the chemicals, not balanced):
__________ + __________ ® __________
4. Now show the balanced chemical equation for the reaction observed:
5. What type of reaction was this? (Synthesis, etc)
