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

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

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.

Measurement and Density Your Name: ____________________________________________________________ __ Purpose of this Lab What is the goal of this lab? What question are you trying to answer‚ or what problem are you trying to explain? Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about each experiment: Experiment 1: Which method of finding the density give you the least percent error and why? Experiment 2: After completing the first

rehydrated to the original state and the percent of the hydrate recovered was calculated by using the mass of the rehydrated sample by the mass of the original hydrate and then multiplied by 100%. Data Presentation & Analysis Table 1: The data was collected from the lab experiment. Sample calculations are shown. Mass of beaker with sample 30.765g Mass of empty beaker 30.263g Mass of sample .502g Mass of beaker with sample after 1st heat 30.661g Mass of beaker with sample after 2nd heat

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
