Prediction: I predict that the higher the amount of Hydrogen Peroxide I use then the faster the displacement reaction will be. Therefore, the less substrate I use then the slower the displacement reaction will be. Hypothesis: I performed a preliminary experiment to distinguish the amount of yeast I will use for the actual experiment. 0.5 grams 1.0 gram 1.5 gram 2.0 grams 2.5 grams 30 72 94 140 202 This therefore shows me that the amount of yeast is directly proportional to the amount of bubbles. Apparatus: In order to complete this experiment I will need the following apparatus * Measuring beaker * Measuring cylinder * Side arm test tube & cork * Rubber bung * Large syringe * Small syringe * Metal rod * Metal scoop * Electronic scales * Stop watch * Goggles * Hydrogen Peroxide * Water * Yeast Method: To begin this experiment I set up...
