quantitatively determined by heating the unknown hydrate to constant mass and calculating the ratio of the moles of water to the moles of anhydrous material. Observations will be made of any color changes during heating and re-hydration of the compound as well as heat effects during the re-hydration. A hydrate is a compound that is associated with a definite number of water molecules. The water is present as individual water molecules and usually no chemical bonds are involved in holding the ions of the compound

are both different types of the physical form of Carbon. Diamond Structure: Giant covalent lattice of carbon atoms. Each Carbon atom is bonded to 4 others which tetrahedrally surround the atom. They have a high melting point as a large amount of heat energy is needed to break their bonds. They are unable to conduct electricity as they have no free mobile electrons to carry the current. Diamond is very hard as there are many bonds within the substance. It is the hardest natural substance and is

crucible. Weigh crucible‚ cover‚ and crystals and record mass in data table. * Set crucible at angle in triangle held in ring on ring stand. Cover crucible loosely with crucible cover‚ and heat gently. Alum will melt‚ and water of hydration will evaporate. * After bubbling has stopped‚ heat sample more strongly for five minutes. * Turn off gas and remove burner. * Using tongs‚ remove crucible cover and place it on wire gauze on tabletop. With tongs‚ remove crucible

open end of the balloon on the test tube and heat CuCO3 for about five minutes. Observe the color change and the balloon. C. Single Replacement: Stand a clean and dry test tube on the test tube rack and add about 5mL of HCl. Carefully drop a piece of zinc metal and observe briefly. Quickly cover the test tube with a cork and after a minute‚ insert a lighted match on the mouth of the test tube. A “Pop” indicates the presence of hydrogen. Pour 5mL of CuSO4 in a clean test tube and add a piece of zinc
