Decomposition of hydrogen peroxide • determine the formula of copper oxide by reduction of the oxide to copper • determine the formula of a hydrated salt such as barium chloride or copper sulfate by heating to drive off water of crystallisation • prepare a substance and calculate the % yield given the theoretical yield. Aim : to investigate the type of reaction that takes place when hydrogen peroxide reacts with liver, and when it reacts with potato, and to determine whether the two reactions are endothermic or exothermic hypothesis : if hydrogen peroxide is added to liver/potato, the reactions should be exothermic, that is, the temperature. The investigation was carried out to determine how different ph levels and hydrogen concentrations, affect the activity of catalase in potato during the decomposition of hydrogen peroxide to produce water and oxygen different variables (independent, dependent and controlled) were put into consideration. A level biology coursework - effect of substrate concentration on rate of activity of the enzyme catalase aim: to investigate the effect of substrate concentration on the rate of activity of the enzyme catalase hypothesis i believe that as the concentration of the hydrogen peroxide (substrate) decreases, the. Yes, it's a chore, but everyone's got to do their isa - it's part of the gcse exam these pages contain some helpful tips and advice see also: 'finishing off your coursework' perfect planning info: you must mention catalase and the reaction it performs with hydrogen peroxide (give the equation) error:.
Planning the accommodation1 this booklet is a guide to planning new laboratories and adapting existing facilities science teaching needs a variety of areas including laboratories, stores, technician workshops or preparation rooms, resource areas and office space for teachers siting all the science accommodation in one. Examine how science works in biology, chemistry and physics contexts examination questions will use examples that are both familiar and unfamiliar to candidates all applications will use the knowledge and understanding developed through the substantive content tiering of subject content in this specification there is. This not some definitive list and is more appropriate to chemistry, but it should give you some idea how to think on risk assessment for some coursework project the use of hazard warning signs with common examples, and may not provide sufficient detail for specific experiments, concentrations, coursework write up etc,.
