MODULE 1: THE CHEMICAL EARTH 3.1.1: Elements in Earth are present mostly as compounds because of interactions at the atomic level * Identify that matter is made of particles that are continuously moving and interacting Matter: anything that has mass and occupies space. Exists in three different states: solid (s)‚ liquid (l) and gas (g) The Particle Theory: “All matter is made up of small‚ indivisible particles called atoms that are continuously moving” | Solid | Liquid | Gas | Particle

Detecting Signs of Chemical Change REAC 399 Prepared by: Elizabeth G. Perez Date of experiment: October 3‚ 2006 Course: Chemistry 100/60 Abstract: The objective of this experiment will be to combine various substances‚ liquids and metals‚ and to observe their behavior when they are combined. The types of reactions observed shall determine the nature of these reactions: physical or chemical. Introduction: An elements¡¦ reaction to certain substances may be predicted by its

1. Briefly explain the following: a. Chemical equilibrium- Chemical equilibrium is the state of a reaction when the concentrations of the reactants and products are no longer changing and remain constant. The forward reaction proceeds at the same rate as the reverse reactions making them equal. This type of equilibrium is also named dynamic equilibrium or a dynamic process. When a reaction has reached its chemical equilibrium‚ the constant K value will remain constant unless the temperature changes

Chemical reactions are a part of everyday lives. Whether it is the burning of propane at a kitchen stove‚ or washing detergent reacting with dirt stains‚ chemical reactions are useful tools that have widespread applications. With so many reactions assisting our everyday activities‚ it is important that ways to optimise reaction rates are investigated. “Reaction rate‚ the speed at which a chemical reaction proceeds… may be defined in terms of the amounts of the reactants consumed or products formed

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

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

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

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
