Chemical Reactions Lab Essay

Gonzalez a chemistry student at Texas State University and my lab partner, Colten and I where instructed to see if the combination and specific concentrations of sodium thiosulfate plus sodium hypochlorite are able to produce second degree burns on a person within 10 seconds. In order for a second degree burn to be possible we must reach a temperature of at least 56°C (133°F) in order to create burns up to third degree for the time the chemical stayed on the worker. Now the dumpster contained 6%…

Interpretation 1. Theoretical Lab Discussion This lab occurs due to enzyme kinetics, and the kinetics molecular theory. Enzyme kinetics is the study of chemical reactions that are catalysed by enzymes, and during the experiments, the reaction rate was measured by the effects of the varying conditions the substrate was in. Influence of Catalase Concentration The higher the concentration of the enzyme catalase, the function of the enzyme occurs better. As the number of disks increased, the…

The objective of this lab is to measure the activity of an enzyme and the effects of environment conditions on enzyme activity. Enzymes are catalysts; agents that speed up chemical reactions by lowering the activation energy required. This means that a catalyst helps reactions occur at a greater speed and lower temperature. For this lab report we focused on the enzyme Tyrosinase, Tyrosinase is an enzyme that produces melanin from the amino acid tyrosine. Three different reactions were catalyzed…

magnesium and oxygen in this equation: Mg + O2 → MgxOy Since an ionic compound is the hopeful result of this lab, an ionic compound is a chemical compound comprising ions, which ions are an atom or molecule with a net electric charge due to the loss or gain of an electron. Ions can be negatively charged and called anions, or positively charged and called anions. But in this lab, many concepts and techniques will be used to get this compound. The main technique that will be used is heating…

titration. A chemical reaction occurs when two or more substances change to form different molecules. In each reaction there are ratios between each reactants. Certain amounts of each reactant are needed to fully complete the chemical reaction. Stoichiometry is the relationship between the quantities of the reactants. An acid is a substance that reacts and donates H+ ions. A base is a substance that accepts H+ ions. An acid that donates more that two H+ ions is polyprotic. In a reaction where an…

The purpose of this lab is to calculate a value for Avogadro’s number and compare it to the actual value for Avogadro’s number. Avogadro’s number will be determined by setting up an electrochemical cell to oxidize a copper electrode. The results of the amount of copper deposited and the average current used will be used to calculate a value for Avogadro’s number. Techniques used: In this experiment, different techniques will be used to collect the required data, such as taking the mass of…

Lab report Questions What will happen when zinc is placed in copper (II) sulfate? What will happen when copper is placed in copper (II) sulfate? Prediction It is predicted that when you place zinc and copper (II) sulfate a reaction will occur, resulting in a precipitation. The prediction about the copper (II) sulfate and copper is that nothing will happen. Hypothesis It is hypothesised that when zinc is placed in aqueous copper (II) sulfate, a single displacement reaction will occur as the…

The purpose of this lab was to determine if a change in mass occurs during a chemical reaction in a closed system. To conduct this experiment, the mass of the test tube, rubber cover, and other materials must be measured. To prevent the test tube from rolling off of the balance, a plastic cup was used to hold it in place, but the group had to remember to zero out the cup on the balance so the cup’s mass will not affect the masses of the objects the group was trying to measure. During this…

catalysts that speed up reactions that occur by lowering the activation energy of the reactants. By lowering the activation energy, the chemical bonds are weakened, thus the reactions are much faster than without the catalyst. Enzymes are composed of proteins which shape dictates the function of the enzyme. On the enzyme it contains a part called the active site where the substrate binds and the chemical reaction undergoes. A substrate is the chemical involved in the reaction. This fit between…

possible to teach me something about the way the world worked, whether it was the way ingredients went together and interacted to form the texture of playdough or why adding baking soda to cake batter made it rise. either way, I was inundated with chemical reactions and techniques before I even knew there was a word for it and this inundation created an undeniable curiosity. Before entering high school, I had an undeterrable drive to know why, why something happened, why it worked, why it was…
