Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules

Lab: Comparison of Three Isomers of Butanol Pre-lab: 1. Write the general reaction of an alcohol and HCl. 2. What would the solubility be of an alcohol in water. 3. What would the solubility be of an alkyl halide in water? 4. What is the purpose of KMnO4 in the reactions? Safety: Concentrated hydrochloric acid is corrosive and the vapour is very irritating to the respiratory system. Avoid contact with skin‚ eyes‚ clothing‚ and the lab bench. Wear eye protection and a lab apron.

Lab 2 Physics 190 Acceleration “g” Due to Gravity – Method 2 Introduction Tonight we will measure the acceleration due to gravity again. This time however‚ we will collect more data and the analysis will be different. We will first fit the data using a second order polynomial. Recall for a mass falling from rest‚ that 1 (1.1) y a yt 2 2 Suppose a mass falls through n successively greater displacements‚ each time starting from rest. The displacements can be expressed a 2 y y t ;

Sample Lab Report: Factors which Affect the Activity of the Enzyme Catalase Purpose: Must include: background information about concepts involved in the lab‚ statement of purpose of the lab identification of independent and dependent variables. A hypothesis is often not necessary or appropriate. Enzymes are proteins that speed up chemical reactions in cells. They break down molecules called substrates. Each enzyme has only one substrate that it breaks down. Enzymes are produced in

Density (Linearized plot) TA: Blue Rex rex Group Members: Billy and Mandy Tuesday; 1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then

Boyle’s Law Lab Purpose: To determine the relationship between pressure exerted and volume of a gas. Materials: Lab simulation. Procedure: 1. Open animation file 2. Modify the number of books that press down on the piston starting from 0 books and increasing by 1 each time until 19 books. 3. Record the pressure (# of books) and volume for 19 different pressure values. 4. Record those values in a table 5. Using the data‚ plot a graph of pressure in function of volume. Conclusion:
