Task: I will investigate on how the concentrations of Hydrogen Peroxide will affect the speed at which Hydrogen Peroxide decomposes into water and oxygen. I will use concentrations of 0.2M, 0.3M and 0.4M. I will also use Manganese (iv) oxide catalyst in view of the fact that Hydrogen Peroxide particles will need less energy to collide with Manganese (iv) oxide particles. Outline Plan: * Using detailed scientific knowledge. * Following safety procedures. * Using the most accurate equipment I can find. * Produce reliable evidence and record it clearly. Equipment: Prediction: I predict that if I increase the concentration of Hydrogen Peroxide the amount of oxygen produced will increase which shows that Manganese (iv) oxide is decomposing the hydrogen peroxide quicker. The reason for this is that there are more collisions between Hydrogen Peroxide particles and Manganese (iv) oxide particles due to the higher amount of particles contained within Hydrogen Peroxide. Probably if I doubled the concentration of the Hydrogen...
