Chemical Reactions Lab Report

142 Words1 Page

In this experiment, chemical reactions take place in cells and are responsible for all the actions of organisms. Chemical reactions can consume energy (endergonic) or release energy (exergonic). Together, these reactions make up an organism 's metabolism. The chemicals taking part in these reactions are called metabolites.

In all reactions:

chemical bonds in the reacting molecules are broken; this takes in energy new chemical bonds form to make the products; this gives out energy
When a chemical reaction takes place energy is either taken in or released. This depends on the relative strengths of bonds being broken and bonds being formed.

In an exergonic reaction, energy is released to the surroundings. The bonds being formed are stronger

    Chemical bonding, also known as chemical reactions, are happening all around us. From cold packs we use on various injuries to the water we drink, they’re all results of chemical bonding. To be more specific, endothermic and exothermic reactions are both types of chemical reactions that are classified by the heat energy that is either released or absorbed when a reaction occurs. An example of an endothermic reaction would be an “instant cold pack”, which become chilled when activated. As for exothermic reactions, “hot packs” make great examples due to their significant temperature increase in just a few minutes.

    A mixture of elements is what is known as compounds. Chemical reactions occur when particles react with each other and atoms in molecules get rearranged. Reactions happen either rapidly or slowly. The speed of a reaction is known as the rate of the reaction. This speed of chemical reaction depends on many factors such as temperature, particle size of reactants, and the intensity of reactants.

    For this lab the knowledge to tell the difference between a chemical and physical changes was needed. To tell this the knowledge of the five signs of a chemical change was needed. These five signs are color change, odor change, production of bubbles/gas, production of heat/light, and the production of precipitate. Also prior to the lab one question was provided that needed to be answered. This question was what chemical must be present for a color change.

    The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

    This lab’s end result was to correctly identify each unknown solution using prior knowledge of chemical properties and the results of the first experiment conducted. Unknown solution D was the only colored solution, being blue while the others were clear. This made it easy to then match D up to Copper Sulfate because of its color. As unknown A and B were added together, lots of gaseous bubbles formed and revealed the fact that that reaction was the reaction between Hydrochloric Acid and Sodium Carbonate because it was the only reaction that produced a gas release. Unknown A and C produced the only yellow, brown precipitate just as the reaction between Sodium Carbonate and Silver Nitrate had previously.

    ST Report In the experiment, the problem was the contaminants that were affecting the quality of the water samples. To fix this issue, three scientists had to determine the contaminants that were present in the samples. One sample was from the school sink and the second sample was from an unknown source. The scientists conducted many tests to figure out what pollutants were present in the water.

    The question is, how does a physical or chemical change affect the mass of a substance within a closed system? To respond to this question, my group did a lab to determine whether or not the mass would change or not. Our lab was to have a plastic bag containing baking soda, then add a cup of vinegar and a block of clay to the mix. We made sure to weight every element separately and then add them up for our total mass of 31 grams before the reaction. During the reaction, as soon as the vinegar was poured in there was a gas produced, bubbles.

    Substance that accelerate chemical reactions are known as catalysts. Enzymes are biological catalysts, because they accelerate chemical reactions that occur in cells. Activation energy is required to start a chemical reaction. Enzymes lower the activation energy needed for the reaction and cause the reaction to accelerate We buy the Hydrogen Peroxide solution form pharmacies and extract the catalysts from the potato.

    The purpose of this experiment was to observe and conclude the impact of a higher alkalinity and increasing sodium chloride concentration had on the yield of lysozyme crystals through crystallization. The constants for this process were sodium acetate at a concertation 0.05 M for every well in both rows, along with the concentration of polyethylene glycol (PEG) being set at 10% for every well in both rows. The two rows of wells that were tested deviated in alkalinity, row A having a pH of 4.5 and row B having a pH of 4.8, along with the sodium chloride concentration of each well. The concentration was increased by 0.5 M each well following the control well of 0.0 M sodium chloride.

    Title: THE BALLOON INFLATION REACTION Introduction: Chemistry is one thing that makes us understand and gives us reasons of why certain reactions gives certain results. In this experiment we will be illustrating the reaction between baking powder and vinegar and see what happens to the balloon that is attached to it. Hypothetically the reaction of the vinegar and baking powder will produce carbon dioxide which will inflate the balloon. If the more vinegar may happen that when more vinegar is added to the baking powder it may produce more carbon dioxide thus the balloons diameter increases.

    The Wittig reaction is valuable reaction. It has unique properties that allows for a carbon=carbon double bond to form from where a C=O double bond used to be located. Creating additional C=C double bonds is valuable due to its use in synthesis. The Wittig reaction will allow the synthesis of Stilbene (E and Z) from a Benzaldehyde (Ketcha, 141).
