Jared Blum September 24, 2001 Group 5 (Jared Blum & Michael Meirrovici) Physical Science 416 Burning of copper oxide and carbon Submitted to: Mr. Longo /10 Definition of the Problem: Purpose of the Experiment Testing of Cylinder, yellow rock, magnesium, sulfur and zinc To observe the results of the solids under 5 tests. (Conductivity indicator, magnetic test, water solubility test, conductivity of soln and test with Hcl, density test ) To observe all of the solids physical properties The Information, Variables, and Techniques I Used Using each apparatus correctly: I. Watch glass: use the watch glass during the massing process. (after finding the wait of the watch glass itself) II. Massing scale: use to find the mass of a given object.
III. Measuring cylinder: use to find the volume of a given object.
IV. Magnet: use to find the magnetic properties of a given object V. Dish well: place water inside a single well to perform solubility test.

Substance
English: Cobalt chloride in various stages of equi...VI. Spatula: use to remove a certain amount of the powders from their test tubes.
VII. Hydrochloric acid: use to check for reaction.
VIII. Conductivity Tester: use the metal rods to observe if the light turns on and also observe the intensity of the light.
Observing and Interpreting the results of those tests: I. Magnetic testing: If the object is attracted to the magnet it is magnetic.
II. Conductivity Tester: If the light becomes lit, the object is conductive. The brightness indicates conductivity.
III. Water solubility test: If the substance dissolves in water it is soluble.
IV. Conductivity of soln: If the light becomes lit, the soln is conductive. The brightness indicates conductivity.
V. Hydrochloric acid test: If the substance shows signs of reaction (bubbling, smoke etc.) it is reactive.
VI. Density: the mass of the substance over the volume...
