    JOURNEY TO THE CENTER OF PHYSICAL FITNESS KESHNI KOKILAKUMAR CLIFTON SPEARS As I walked through the doors of the small yet strangely familiar gym of Ridgeview Middle School‚ thoughts rushed back and forth through my mind. They were simple thoughts‚ though each of them turned into questions. I had signed up through Fulton Virtual Schools‚ and since this was the first time that they were opening the Physical Fitness program to us‚ I couldn’t help but feel slightly anxious. I had already experienced

    CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚

    for each of your answers. 1. Explain in your own words what it means for a chemical system to be in the state of dynamic equilibrium.
 After a reaction has occurred for awhile at a given temperature‚ the forward and reverse reaction rate will eventually be equal. Although you may get this confused‚ the concentration may not be equal‚ but the rate will. This occurs in a closed system. In other terms‚ dynamic equilibrium is when no change appears; as the rate of reverse and forward are equal.

    The career path I have chosen to pursue is physical therapy. As I was growing up‚ physical therapy was not an option I would have considered but ever since junior year‚ my love for physical therapy has grown and pretty much eliminated all other career options. I had never fully understood what a physical therapist did until I became a patient. In the beginning of my junior year I had torn my anterior cruciate ligament (ACL)‚ medial cruciate ligament (MCL)‚ and medial meniscus while playing goalkeeper

    that the hypothesis is supported and it was correct. In the conclusion‚ it was shown that the temperature has the ability to speed up or give the particles more energy and therefore effect the rate of reaction. 2. Background information: Ionic bonds formed between two ions by the transfer of electrons. The speed at which a chemical reaction proceeds is known as the rate of reaction. The rate of almost every reaction can be increased or decreased due to different factor. Scientists

    Lecture No. 1 Chemical Kinetics 1.1 The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate

    Properties of Chemical Reactions Ms. Whitty‚ Science 10 Fiona Adams‚ November 1st‚ 2012 Introduction Chemical reactions are a part of our daily lives‚ from rusting metal to making bread to leaves changing colour in the fall. A chemical reaction is the process that occurs when two or more substances combine to produce a chemical change. When a chemical reaction takes place‚ the change is indicated by one or more qualitative properties. The colour or odor could change‚ gas could be produced
