The purpose of the lab was to find out the chemical elements based on the color of the flame that elements make by their reaction. The work we completed in the lab was testing the chemical effects of the flame from the chemicals. We tested different elements and wrote down our observations. I accomplished the knowledge of testing chemicals and making responses based on our observations.Electrons are the particles found in the chemicals that may be responsible for the production of colored light.

Chemical Reaction: Cold Packs CHM110 Chemical Reaction: Cold Packs Introduction Chemical reactions happen every day in a variety of ways. We will explore the science behind cold packs and the chemical reactions that happen at the molecular level. Furthermore‚ we will examine and explain what chemical bonds are formed‚ broken‚ or both. The product is a simple construct of two bags: one containing water (solvent) and the other a chemical compound called ammonium nitrate (NH4NO3). In order to activate

Introduction: A chemical reaction involves the breaking and forming of bonds in order to create the necessary energy required to cause movement. Each reaction is catalyzed (an increase in rate because of a present catalyst) by a specific enzyme. Enzymes are able to denature proteins‚ meaning that a protein loses its original shape by uncoiling‚ giving it a random‚ unstructured shape. The pineapple plant contains bromelain which‚ because of its unique characteristics‚ keeps gelatin from thickening

Mass relationships in a chemical reaction Introduction: The Law of Conservation of Mass dates from Antoine Lavoisier’s 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words‚ the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction‚ the total mass will be the same at any point in time in any closed system. http://www.nature

Oscillating chemical reaction Aim: The overall reaction rate and concentrations of some reaction intermediates of certain chemical reactions oscillate‚ even in a homogeneous system. This phenomenon is commonly found in living organisms. These periodical variations occur when a feedback mechanism is available in which a product changes the reaction rate. In this experiment will produce oscillations in both time and space in the concentrations of cerium(IV) and cerium(III) in the BZ reaction. Use the

Chemical Reaction of copper compounds Introduction: In this experiment‚ the objective was to conduct a series of chemical reactions that contain copper or copper compounds. That is to say that the products of each chemical reaction were used in the next reaction. The process starts with a solid copper wire dissolved in nitric acid and the end product is copper powder. The product which was used from the previous reaction is the limiting. In the initial step‚ the solid copper is the limiting reactant
