Determination of the Waters of Crystallisation/ Water of Hydration, In Hydrated copper (II) Sulphate Introduction In nature there are some salts that will have water in their crystalline structure. These salts are commonly known as hydrated salts. Hydrated Copper (II) sulphate is one of these, as suggested by the use of the word hydrated in…

Introduction: Lycopene is a carotene because of its carbon and hydrogen composition. It is red in color and a member of the carotenoid family. Members of the carotenoid family play integral roles in plants. They use the absorption of light to aid in photosynthesis, and protect chlorophyll from damage. In humans, Lycopene acts as an…

My hypothesis is that dissolved Phosphate will change for the total phosphorus when left under a light. I believe that suspended phosphorus has the biggest impact on the eutrophication of lakes. When there is an increase of phosphorus in lakes, this leads to and increase in phytoplankton. This then leads to a decrease in water…

Cloud Formation Cloud A cloud is a visible mass of condensation droplets. Water moves into the atmosphere through the process of evaporation and transpiration. Water vapors join the dust particles in the atmosphere to form clouds.  Finally, water returns to Earth as precipitation in the form of rain, snow, and hail. Clouds cannot be formed…
