Honors Period: 5 February 29, 2016 Chemical Reaction Lab Report Introduction A chemical reaction is when substances (reactants) change into other substances (products). The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. In this lab, the five general types of chemical reactions were conducted and observations were
Title: Chemical Reaction Types and Their Equations 2. Purpose: The purpose of this lab is to further observe four types of chemical reactions. This lab will show four types of distinct chemical reactions and will increase my knowledge on each type. 3. Procedure: In the first experiment (Synthesis Reaction) 5g of Mg was heated with a Bunson burner to perform a reaction. In the second experiment (Decomposition Reaction) 5g of Cu2Co3 was heated with a Bunson burner to perform a chemical reaction with
Lab Report Kinetics of Chemical Reactions Kinetics of chemical reactions is how fast a reaction occurs and determining how the presence of reactants affects reaction rates. In this experiment the rate of reaction for Fe+3 and I- is determined. Because the rate of chemical reactions relates directly to concentration of reactants, the rate law is used to find the rate constant, and calculated with specified temperatures. Two catalyst reactants are used in the experiment, thiosulfate and starch
Qualitative Observation of a Chemical Reaction Purpose: Carefully observe and interpret a chemical reaction. Apparatus: Equipment- 250mL beaker, 125mL Erlenmeyer flask, cardboard square, chemical scoop, metric ruler, lab countertop, rubber stoppers, safety goggles, lab apron Materials- candle ( 2cm diameter), matchbook, 2 toothpicks, Limewater solution, string, aluminum foil, Cobalt Chloride paper Procedure: Note appearance, odor, and feel of the unlighted candle. Heat the bottom of the candle
The purpose of the lab is to study the effect of a chemical reaction, on the change in mass. Procedure: 1.Place Alka-Seltzer tablet into bottle cap. 2.Pour approximately ⅓ of bottle volume of water into the Coca-Cola bottle. 3.Using a scale, mass the bottle with water and the cap with the tablet. 4.Combine the two reactants by inserting the tablet into the bottle and by quickly screwing the bottle cap onto the bottle. 5.After the reaction occurs, mass the newly dissolved solution. 6

LAB REPORT 4 Observations of Chemical and Physical Change PART 1 – OBSERVATIONS OF CHEMICAL CHANGE No credit will be given for this lab report if the Data section is not completely filled out and if the required photographs are not received. At least one photograph must show the student’s face. OBJECTIVES 1. Observe physical and chemical changes. 2. Define physical and chemical change. 3. Identify the relationship between a chemical change and a chemical reaction. 4. Observe several indicators
CHEM 2123 and 2125 – Organic Chemistry Lab I and II GUIDELINES FOR WRITING LAB REPORTS INTRODUCTION Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed to organize experimental data in a format similar to that required for publication in major scientific journals. Here are some important considerations that apply in research settings
Lab Report on Measuring the Rate of Conversion of Hydrogen Peroxide using Enzyme Catalysis In essence, the main objective was to use chemical titration to measure and then calculate the rate of conversion of hydrogen peroxide (H2O2) to water and oxygen by using the enzyme catalase. Other purposes of the lab were; to measure the effects of changes of temperature, pH, enzymes concentration, and substrate concentration on rates of an enzyme. The lab was also an opportunity to see a catalyzed reaction
