Place the crucible with magnesium over the Bunsen burner in the pipe clay triangle and put the lid on. Once the crucible is hot, lift the lid with tongs. The magnesium may flare. Continue to heat and lift the lid until you see no more reaction. Remove the crucible from the flame and allow to cool. Re-weigh the crucible with lid and the burned magnesium. The formula is magnesium + oxygen = magnesium oxide. Creating Iron Oxide Cover one end of the meter ruler with foil to protect it from the Bunsen burner. Attach a few strands of steel wool to the end of the ruler. Balance the ruler on a knife edge or triangular block at the 50 cm mark. Weight the empty end with plasticine until this end is just down. Heat the wool over the flame for about a minute. The wool will glow. When placed on the triangular block, the ruler will tip in the wool until the wool side of the ruler is down. The formula is iron + oxygen = iron oxide. Reconstituting Stearic Acid Place stearic acid in a boiling test tube.
