  • Chemical Reactions Lab

    Chemical Reactions I Purpose The purpose of this experiment was to test and see how four different chemical reaction worked. The four different chemical reactions are formation, decomposition, single-replacement, and double-replacement. The hypothesis of this experiment was that in each of the different reactions something would happen to the reactant whether it be color, mass, temperature, or pressure. II Equipment For this experiment Late Nite lab was used. In Late Nite Lab the equipment was: a balance, a crucible, a Bunsen Burner, a 150 mL Erlenmeyer flask, a thermometer, a pressure gauge, a syringe, two 50 mL beakers, magnesium (Mg), Copper(II) Carbonate Hydroxide Hydrate (Cu2CO3(OH)2 x H2O,) 6M Hydrochloric acid (HCl), Zinc (Zn),…

  • Chemical Reaction Lab Report

    In this lab there was 2 objectives which where to recognize when a chemical reaction has occurred and practice collecting detailed observations in the laboratory using proper scientific terms. Reaction set #1 (1a) place approximately 1 ml of 0.1 M Pb (No3)2 solution into a test tube. Then sequentially add drops of 0.25M k2CRO4 solution until you see evidence of a chemical reaction. The products of this reaction are aqueous KNO3 and solid PbCrO4. (1b) place approximately I ml of .1M Pb (NO3)2…

  • Chemical Reaction Lab

    The Rate of Chemical Reaction and the Factors Affecting Reaction Rates The purpose of these labs is to investigate and determine how three factors- concentration, temperature, and a catalyst- affect the rate of a chemical reaction. In the first lab, “Rate of Chemical Reaction,” 1 x 8-well micro strips were used to combine a potassium iodate solution and a sodium meta-bisulfite solution under different conditions; each trial was timed from the point of the first visible reaction until the last…

  • Lab Report: Classifying Chemical Reactions

    “Classifying Chemical Reactions - Lab Report” I - Introduction - Chemistry is the study of the composition, structure, properties and change of matter. In chemistry, chemical and physical changes are used to help scientists understand how different substances react given various circumstances. A chemical change is any change resulting in the formation of a new chemical substance(s). A physical property is any change that does not involve the chemical makeup of a substance at all. In total…

  • Lab Report: Redox Chemical Reactions

    appearance. In part I, reaction one produced a blinding, bright white light when the metal burned and the metal turned into a white powdery substance. For reaction two, there was no reaction at first and it took a long time for it to react, but then bubbles started to form around the magnesium ribbon and the substance turned into a pink-yellowish color around the magnesium strip when it was placed in the 150 milliliters beaker. The physical observations of reaction three was the magnesium strip…

  • Crystal Chemical Reaction Lab Report

    Haines et al., A neutron diffraction study of quartz-type FePO4: high-temperature behavior and αβ phase transition Kristallogr. 218, 193-200 (2003) Paragraph 1 Crystal chemical relationship between quartz (SiO2) and FePO4 Silicon dioxide is an oxide of silicon with the chemical formula of SiO2. SiO2 is a chemical compound most commonly found in Quartz and it has a space group of P3121. The lattice symmetry of SiO2 is tetrahedron, where there are 4 oxygen atoms covalently bonded to the silicon…

  • Reversible Chemical Reaction Lab

    Introduction: A reversible chemical reaction is a reaction which can proceed in both the forward and backward directions which can be represented by the symbol . A reaction comes to equilibrium when the rate of reaction of the reactants is equal to that of the rate of reaction of the products. An example of a reversible chemical reaction is one which occurs in the pool between chlorine and water (Deb Smith, 2006). Equation 1 A reaction takes place with water to produce hypochlorous acid, HOCL…

  • Enzyme Concentration Lab Report

    Concentration on Reaction Rates and Pressure Background - While conducting the Enzyme Lab, students used enzymes as catalysts in order to speed up the reaction processes involved in several tests. Enzymes are substances produced by living organisms that act as a catalyst, while a catalyst is a substance that increases the rate of the chemical reaction. Furthermore, varying amounts of pH and enzymes were added to the mixture in order to determine the substance’s rate of reaction. When the…

  • Endothetermic Or Exothermic?

    Endothermic or Exothermic? The energy changes lab was an interesting lab in which the class compared two chemical reactions, the solute baking soda and the solvent vinegar, and the solvent baking soda solution with the solute of calcium chloride to see whether the changes were endothermic or exothermic reactions. I concluded that vinegar and baking soda was the endothermic reaction and baking soda solution and calcium chloride was the exothermic reaction. I knew this because in the vinegar and…

  • Green Chemistry Principle Lab Report

    Introduction: In this lab, I determined what type of reactions could be performed based off of experiments. Six experiments were chosen out of twelve. These six experiments were chosen based off of what Green Chemistry Principle(s) they followed. The purpose of this lab was to perform each experiment correctly and according to the Green Chemistry Principles. There were four parts to this lab. The first part was to familiarize myself with the Bunsen Burner by sketching it out in my laboratory…
