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 its name. Its molecular structure is shown below. The water that is chemically combined into their structure is called the water of crystallisation.

An Investigation on the rate of reaction of the enzyme Catalase on the substrate Hydrogen peroxide. Plan Aim: To investigate the rate of the effect of Catalase on hydrogen peroxide. Introduction This investigation will be carried out to investigate the rate of reaction of the enzyme catalase on the substrate hydrogen peroxide. Enzymes are biological catalysts‚ which speed up the rate of reaction without being used up during the reaction‚ which take place in living organisms. They do this by

Film Analysis Within every man resides good and evil; which quality manifests itself is determined by how one is raised and views the world. Stanley Kubrick’s film Full Metal Jacket takes the concept of good or evil in man and shows how war‚ the marines‚ and government blur soldiers’ ideas of right or wrong. By injection of propaganda from these sources a misidentity is created within the solider. Once this misidentity has taken place it is the soldiers’ job to figure out what he is: a killing machine

System of a Down System of a Down (System) is an Armenian metal band that formed in the early 90 ’s. When System first formed they became incredibly popular among teenagers. System is also widely known for their controversial and political songs. The current members of System are Serj Tankian‚ Daron Malakian‚ Shavo Odadjian‚ John Dolmayan. System first formed under the name of soil. When Soil broke up Serj‚ Daron‚ and Shavo decided to form a new band and they called it System of a down. The name

AP Chemistry Dr. Istone Lab 3: Gravimetric Analysis of a Metal Carbonate Lab Objective: In this lab we will determine the identity of a group 1 metal carbonate compound by gravimetric analysis. The unknown is weighed and dissolved in water and the precipitate is filtered‚ dried‚ and weighed. From the data the formula weight and identity of the unknown metal carbonate is determined. Lab Procedure: 1. Set up the Bunsen burner and ring clamp‚ light the burner and heat the crucible

The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates
