    one of the tests‚ so that data is lost. Specific errors include measuring the entire test tube from top to bottom instead of measuring the exact distance traveled by the filter paper‚ making the test results not plausible. The results of this lab proved several things. The results of the first test show that a higher enzyme concentration causes a faster rate of the substrate being broken down. This means that the effect of enzyme concentration on enzyme activity is a positive effect and speeds

    Collecting Photosynthetic Rates in Spinach (Spinacia oleracea) Introduction: The purpose of this study was to see which light color would cause the spinach sample to photosynthesize the most within the given time. In order to understand photosynthesis‚ we need to know that chloroplasts absorb light energy from the sun‚ the plant then takes that energy along with water and carbon dioxide and changes it to sugar and oxygen. This happens in order for the plants to grow. But‚ light energy comes in a

    Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 | Instructor: Mr. Nailer | I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT)‚ its mass (m)‚ and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine

TLC results weren’t high enough to conclude that the product was a pure aspirin. Overall‚ the lab wasn’t successful due to the low percentage of aspirin that were produced. Out of 2.0 grams of aspirin‚ only 0.7862 grams of pure aspirin were produced. So the percent yield was only 39%. Errors could be made during filtration process and the melting
