    Review 3: Text Chemical reaction is the changing of substances to other substances by the breaking of bonds in reactants and the formation of new bonds in products. There are many different types of reactions. Many reactions can be assigned to more than one classification. The same reaction can be classified in different ways. It is important and useful to know all the different types of reactions because they often refer the reactions as being of one type or another. The first reaction is Acid-base (Neutralization) Reaction. A neutralization reaction occurs when an acid and base are mixed together. The compound formed by the cation of the base and the anion of the acid is called a salt. The combination of hydrochloric acid and sodium hydroxide produces common table salt. An example is…

  • 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…

  • Investigating Chemical Reactions

    Coffactors Abstact Chemical reaction are a part of every ones life there no dening it this fact. But is there a way to increase these reations and make processed like reasperation and metablolism faster. That is exactly what cofactors are beleived to do, increasing the rate of reaction. In this experirment lactase, ONPG, EDTA, and phosphate buffer are used to determine wether or not cofactors really increase the rate of chemical reation. To measure the reaction a spectrometer will be used.…

  • Chemical Reaction In Cooking Food

    Chemical Reaction A Chemical Reaction is when there is change from physical reaction to nuclear reaction. In chemical reaction, there is also a change of a chemical substance to another, which in that case is the change to one or more productions. It 's when a substance changes and when you combine chemicals or mix them, you 'll most likely create a new one, not always but most of the time it will. Cooking food always involves a chemical reaction. It could be from baking a cake by mixing the…

  • Exploring Chemical Reactions In Chemistry

    In this lab, students learned that in a combination reaction, two or more substances react to form one substance. This can be seen in reaction #2. In reaction #2, magnesium reacts with oxygen to produce magnesium oxide. Although the students can only see magnesium and magnesium oxide, the students were informed on the lab sheet that oxygen was also one of the reactants. This reaction allowed students to see how two substances, magnesium and oxygen, react to produce one product, magnesium oxide.…

  • Chemical Reaction Lab Report

    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…

  • Biological Chemical Reactions Are Catalyzed By Enzymes

    Enzyme Post- lab assignment The purpose of this lab is to see the enzyme activity. We have known that biological chemical reactions are catalyzed by enzymes, so in the experiment 4.1 we tested the properties of catalase, and its presence in potato and sheep blood. The result was we could see the oxygen gas- bubbling by catalase’s presence. Not only that, enzymes are known as reusable, but they are not altered by their reaction with any substrate. In experiment 4.2, we could see that enzymes…

  • 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…

  • 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…

  • Essay On Chemical Reactions

    Introduction: Chemical reactions are a process that involves, rearranging the molecular structure of substances to create new ones. There are 3 types of chemical reactions, firstly there's synthesis, (e.g. 2Na + Cl2 → 2NaCl); then, the other type of reaction is decomposition (CaCO3 → CaO + CO2); and finally there is combustion. Combustion is a rapid chemical combination of a substance (fuel) with oxygen, including the production of heat and light (e.g. CH4 + 2O2 → CO2 + 2H2O). In these types…
