potential of chemically binding to other monomers of the same species) which link in various fashions (e.g. cross-link‚ linear linking) to form materials that are used constantly to help humanity’s comfort and existence thrive. An important innovation of chemical advances is a material known as Hydrogels. What are Polymers and Why Use Carbon and Silicon Atoms? Polymers are repeating chains of monomers (atoms) which link in varying trends depending on their individual properties. These properties determine

2.MATERIALS and METHODS 2.1. Nature of Reactants 2.1.1 We placed 3mL of 3 M HCl into each of 3 seperate test tubes. Next we added mossy zinc to the first test tubes‚ Sn granules to the second and Cu filings to the third and compared the rates of evolution of hydrogen gas in each test tube. 2.1.2. We mixed 3mL of 0.02 M KMnO4 and 2mL of 3 M H2SO4 in a test tube and stirred using a glass rod. Next‚ we divided the solution into two. We added 2mL of 0.03 M Na2C2O4 solution to the first half and

LAB # 6 MASS RELATIONSHIPS IN CHEMICAL CHANGES October 22‚ 2012 Patricia D Partner: Mike C MASS RELATIONSHIPS IN CHEMICAL CHANGES PURPOSE The purpose of this experiment was to study the fundamental idea that in chemical reactions‚ or changes‚ all particles of one substance will have the same average mass‚ but particles of different substances will have average masses different from each other. These changes occur in ratios‚ and rarely

Shanel Warren Tiffany‚ Princess‚ and Wei October 2‚ 2013 Determining the Mole Ratios in a Chemical Reaction Introduction The purpose of this lab was to determine the mole ratios of the reactants hypochlorite ion (OCI ) and thiosulfate (S O ) when reacted in a chemical reaction. A chemical equation gives the mole ratios of the reactants and products involved in the chemical reaction. When some formulas of the products are not known‚ experimental measurements can be made to determine

Heavy Machinery is the prime need of the industries. The machines like bulldozer‚ Skid Steer Machinery‚ excavator‚ wheel loaders‚ drilling machine‚ mixer trucks and many more are used for the construction purposes‚ while the cranes‚ industrial truck‚ forklift and other such machines come in use in the production industry. Therefore‚ it is always recommended to use good machine that generate necessary power and also gets the work done. To buy these typical machines is not an easy task as they are

THE CLASSIFICATION OF CHEMICAL REACTIONS Danny Bhatt SCH3U0-G Mr. Gandhi Wednesday‚ April 1st‚ 2014 INTRODUCTION The purpose of this lab is to determine the different types of chemical reactions and differentiate between them based on similar characteristics of each set category. In this lab it is hypothesized that every chemical reaction which was observed would fall under already set categories (that are: synthesis‚ decomposition‚ single displacement‚ double displacement‚ combustion and

Experiment: 3A The purpose of laboratory assignment 3 was to measure the rate at which a chemical reaction takes place. For the purpose of this lab we measured the rate a balanced oxidation/reduction reaction between iodine‚ hydrogen‚ and bromate ion occurs. The above reaction occurs slowly so we used a coupled iodine clock reaction to measure the rate of the oxidation/reduction reaction because it occurs much faster but is still dependent upon the other reaction. To accomplish this‚ two mixtures

The purpose of the first part of the experiment was to produce a chemical compound which was the alum crystals by using aluminum‚ potassium hydroxide and sulfuric acid. After the compound was present‚ the purpose of the second part of the experiment was to make sure that the compound that was formed in the first half of the experiment was actually alum. Some of the experimental techniques that were used in this experiment was filtration using the Büchner funnel vacuum filtration‚ recrystallization
