Abstract The purpose of this lab was to test if ethanol affects the reaction involving hydrogen peroxide and catalase. Tests were performed by putting chicken liver‚ ethanol solution (diluted ethanol solution for other trials) and hydrogen peroxide in a test tube with a side arm‚ and having a rubber tube lead the oxygen gas into a gas collection tube. Results from the tests showed a negative correlation‚ this means that the more diluted the solution of 95% ethanol was‚ the less oxygen gas collected

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 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 ;

Lab‚ Week # 1 BALANCE LAB Introduction The purpose of this lab is to learn how to utilize two different balances to find the mass of different chemicals in the ChemLab program. A balance is an instrument used to determine the mass of a chemical. To accomplish this we use direct weighing and weighing by difference on both the centigram and electronic balances. Equipment 1 Centigram Balances 1 Electronic Balance 1 100ml Beakers 5 Copper Slugs 2 Unknown Weights (Label # 1‚ # 2)
