Scientific Reaction
...ced into a test tube and heated until there were no more changes. All observations were recorded. Then, 1/3 gdfull of BaCl2 solution was added to the Na2SO4. Obsdfgervations were recorded. Next, a 3cm long strip of Magnesium wgas described. It was held in the flame of a Bunsen burner using tongs. The new product was described. After that, a piece of mossy zinc metal was added to 1/3 of a test tube of dilute H2SO4. A flaming splint was brought to the mouth of the test tube. When that is finished, an iron nail cleaned with sand paper was placed into a test tube and covered with CuSO4. The nail was removed and observed after several minutes. Next, 2cm of KClO3 crystals were placed into a test tube and heated until the crystals melted or boiled. A glowing splint was placed into the mouth of the test tube. Finally, a small piece of FeS was placed in a test tube and several drops of dilute HCl were added. Observations were recorded. In the first reaction, with CuSO4×5H2O and heat, we heat can break down a compound.. I...
