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…
Purpose: The purpose of this lab was to help students understand the different chemical reaction types. The secondary purpose was to help students learn how to balance equations. Procedure: The first thing that was done in the lab the participants will need to read about the first problem, then take notes about their observation. From there a word equation would need to be set up and following that there would need to be a chemical equation. Finally there needs to be a structural model that…
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…
The purpose of this experiment is to show that chemical reactions that are open to the air go through a reaction, they form a gas that ends up getting diffused through the air. This is how the reaction losses mass. In this experiment there was two reactions that were used. HCL was used as an acid, the balanced chemical equation is: NaHCO3(s) + HCL(aq) →NaCl(aq) + CO2(g) + H2O(l). The second reaction that was used was sodium carbonate: Na2Co3(s) + 2HCl(aq) → 2NaCl(aq) + CO2(g) +H2O(l). To start…
Names: Hanan And Samantha Chemical Reactions Formative Assessment Task: Design and conduct an experiment to test whether the reaction between acetic acid and sodium bicarbonate is exothermic or endothermic. NOTE: Academic language scripts have been provided to get you started and to guide your writing. Use them as much as you can to help your writing advance to the next level. They look like this: An academic language script is similar to… The purpose of this investigation is to… Use your…
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.…
Introduction: In this chemistry lab, different types of chemical reactions such as double displacement, single displacement, decomposition, and synthesis reactions were observed. During the lab there 4 stations A, B, C, and D each letter has two different options to choose from. The students job is to choose the option that will create reactants that reach the standards for the reaction to be considered safe. The purpose of this lab is to give students a better understanding of chemical…
The most general types of reactions are: combustion, synthesis, decomposition, precipitation, single-replacement, double-replacement, acid/base, and redox. Combustion is a reaction in which a substance reacts with oxygen to produce a heat explosion. Examples of a combustion reaction would be C + O2 --> CO2, the burning of coal or CH4 + O2 --> CO2 + H2O. Syntheis also known as, composition reaction, is a reaction that consists of two or more substances combined to produce a new…
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…
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.…
