Burning magneseum lab.

Materials:
Bunsen burner, distilled water, tongs, ring stand with ring attached, stirring rod, crucible, clay triangle, scale, conductivity tester and magnesuim.

Safety:
Wear safety goggles, DO NOT LOOK DIRECTLY AT BURNING MAGNESIUM LIGHT COULD DAMAGE EYES, be careful cause materials may be very hot to handle.

Procedure:

  1. Set up ring stand so it is 7 cm above table.
  2. Mass empty crucible and record mass
  3. Roll magnesium into a small ball, measure the mass of magnesium and crucible, then record.
  4. Light bunsen burner.
  5. Place crucible on clay ring and start to heat up crucible.
  6. If magnesium does not light you can pull a small piece of it out of the crucible and light it in the bunsen burner then quickly and carefully put back in crucible.
  7. When magnesium and crucible has cooled down you can place on a scale, mass, and record data.
  8. Then carefully pour 5 mL of distilled water into crucible and stir.
  9. Test conductivity with a conductivity tester and record results.

Results:

After you burn the magnesium the weight increased. The magnesium can also become a electricity conducter if you add distilled water and stir.

Questions:

  1. Magnesium before = .17g Magnesium After = .22g Difference = .05g
  2. Kinetic energy was released from the magnesium because it gave of heat and
    light.
  3. when the magnesium was lit so was the oxygen which gave it very little oxygen to work off of.
  4. MO, M3N2
  5. After the magnesium was done burning what was left behind was some of the product.
  6. Yes. it did conduct electricity. No. nothing showed that it was ionic compounds.
  7. Magnesium didn't melt.
  8. Magnesium is very important to stay physically and mentally healthy.
  9. found in medicine Mg(OH)2 to help relief stomach aches and heartburn. sometimes called milk of magnesium and magnesium hydroxide.
