Factors Affecting Reaction Rate Bob Jones Josh October 2‚ 2014 Period 3 Introduction: In reference to the collision theory‚ molecules act as small spheres that collide and bounce off each other‚ transferring energy among themselves when the collide. In order for a reaction to occur‚ there must be collisions between molecules. Through experimentation‚ factors are discovered that influence the reaction rates of chemical reactions include the concentration

purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an aqueous state or a solid

9/19/2012 Experiment #1-Density Aim: Learn how the process of distillation occurs. Observe how distillation separates alcohol from wine. Method: Distillation is based on the fact that the matter can exist in three phases - - solid‚ liquid and gas. As the temperature of a pure substance is increased‚ it passes through these phases‚ making a transition at a specific temperature from solid to liquid (melting point--mp) and then at a higher temperature from liquid to gas (boiling point--bp). Distillation

CHEM 1211 L Principles of Chemistry Lab 16 February 2004 Lab Report 1 Introduction The purpose of this project is to identify an unknown organic acid (X) by conducting various experiments to determine the acid’s unique properties. By determining selected constant properties of the unknown and then comparing these properties to the constant properties of known substances‚ it is possible to identify an unknown substance. The properties used to identify the unknown must be intensive‚ or independent

transfer 0.8 ml of this solution and the reaction was allowed to proceed until the solution turns brown and cloudy. The conical vial was then rinsed with 2 ml of anhydrous ether to get any remaining solution into the reaction vessel. Simultaneously‚ 1.09 g of benzophenone and 2ml of anhydrous ether were added to a 3ml conical vial and gently stirred. The reaction vessel was taken off of the hot plate and allowed to cool. The benzophenone was then added to the reaction mixture while stirring vigorously.

Observing a Single Chemical Reaction Qualitative vs. Quantitative Observations Abstract: The purpose of this experiment is to help you sharpen your observational skills. The aluminum foil was found to rust in the water containing the dissolved Copper Chloride (CuCl₂) crystals. The results of the experiments were determined through close examination and observation of both qualitative and quantitative elements of the changes that occurred when a blue crystal‚ Copper Chloride‚ reacted with aluminum
