Procedure First of all, the 400-ml beaker was supported on a ring stand. Then, 300-ml of distilled water was added in the beaker. After that, the beaker was bright to a boil. A boiling chip and 20 drops of methyl alcohol were added into a 16x150 mm test tube. The test tube was placed in the hot water. The alcohol started boiled in the test tube, and the boiling point was recorded. Secondly, the solubility of a solid water was calculated by the following procedures. Into two test tubes were added 20 drops of distilled, then one drop of copper sulfate crystal (CuSO) was added into one test tube, and a calcium carbonate crystal (CaCO3) was added into the other test tube. The test tubes were beaten until to observe the changes whether each solid was soluble or insoluble in water. Next, the solubility of a liquid in water was calculated by the following steps. Into two test tubes were added 20 drops of distilled water. One of the test tubes was added a few drops of methyl alcohol, and the another test tube was added amyl alcohol. The test tubes were beaten until the liquids were mixed. Chemical properties, a pea-sized sample of ammonium bicarbonate (NH4HCO3) was added to a small test tube. Then, the test tube was heated with a cool flame; moreover, the changes were recorded, including odor. After that, 20 drops of sodium carbonate and 20 drops of sodium sulfate were added into separate test tubes. 20 drops of dilute hydrochloric acid were added into to each test tube and the changes were recorded. The last one,
