Introduction: The chemical industry has become one of the largest manufacturing industries in the world since the beginning of the 21st century (Murmann‚ 2003). They convert raw materials such as oil‚ natural gas‚ air‚ water‚ metals‚ and minerals into more than 70‚000 synthetic chemicals (United States Department of Commerce‚ n.d.). Heavy demands on chemicals allowed prosperity of materials goods and had brought convenience for many people. Now they can be found everywhere around world‚ and even

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

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

The Inhumane Weapons of Warfare Chemical warfare is a barbaric weapon of war that should be banned from any war situation. Chemical Warfare is using any chemical or chemical mix that can physically or mentally harm a human being. It has been killing people for over 2600 years and was created by Spartans. “They grabbed burning sulfur pitch and threw it over the walls of Athens attempting to fill the city with toxic gas.”[6] They tried this because they had a small army that was trying to take over

research the chemistry behind a chemical reaction that is used in automobiles. Write a page that explains what the reaction is‚ where it occurs in the car‚ and what it does for the car. There are over one billion of cars around the world‚ getting people where they want to go. Therefore‚ automobile transportation became much more important in everyone’s daily life. Chemistry made the automobiles to work. The chemistry and chemical reactions used in many parts of the automobiles. The role of chemistry

Chemical Reactions I. Purpose – The purpose of this lab was to observe different type of chemical reactions to write and balance chemical equations. II. Hypothesis: If you mix two chemicals together‚ then they will change color and/or bubble/fix. III. Procedure - Workstation 1: 1. Light the Bunsen Burner 2. Add 5 – 8 mL of HCL to a test tube that’s in the test tube rack 3. Drop a 2 – cm piece of Mg ribbon into the test tube 4. Record Observations 5. Clean Workstation

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

is made up of tiny particles and they are constantly moving/continual state of motion. 1.1.2 Identify the difference between elements‚ compounds and mixtures in terms of particle theory Elements are simplest form substance meaning cannot be decomposed further physically or chemically. They are made up of same type of atoms only e.g. helium‚ oxygen. Compounds are pure and they consist of 2 or more elements bonded chemically (fixed ratio). They can be decomposed chemically. E.g. sodium chloride
