Abstract For this lab the rate of photosynthesis was analyzed upon plant leaves. A sample of a light exposed and a not-light exposed leave were used to clearly identify the role of sunlight in the process of producing and storing energy. Aim We are trying to find proof‚ to demonstrate the necessity of light and chlorophyll in the process of photosynthesis. Background Photosynthesis occurs in organisms which contain chlorophyll. It’s a process that involves the chloroplasts to synthesize glucose

Design an experiment to investigate the stoichiometric mole ratio of a chemical reaction. Present your data in terms of the mass of one reactant compared to the mass of one product. Purpose: The experiment will be designed to find out the stoichiometric mole ratio of Barium Chloride and Silver Nitrate yielding a precipitate of Silver Chloride in a Barium Nitrate solution. (BaCl2 + 2AgNO3 -> Ba(NO3)2 + 2AgCl) Research Question: How will the amount of Barium Chloride and Silver Nitrate
