Background of the Study Since ancient times‚ farmers have known that adding certain substances to the soil helps produce healthier‚ more abundant crops; such a substance is called fertilizer. The researchers decided to make an organic fertilizer. Organic fertilizers are made up of

Looking back at the research question‚ the actual amount of reactant did not match the theoretical stoichiometric amounts according to the balanced equation‚ but the amount of catalyst matched the original value when uncertainty is taken into account. The percent yields for the reactants in the equation are very far from 100% yield. In the case of water‚ the percent yield came out to be meaning there were at least 2 times to 4 times more water than there should be. The percent yield of oxygen came

rate of the enzyme catalyzed reaction can be calculated. The primary reaction catalyzed by catalase is the decomposition of H2O2 to form water and oxygen. ------------------------------------------------- 2H2O2 → 2H2O+O2(gas) ------------------------------------------------- Catalase + Hydrogen Peroxide --> Complex --> Catalase + Water + Oxygen The materials: * 1.5% H2O2 ‚ H2SO4 ‚ at least 400 ml of catalase and 2% KMNO4. * Distilled water * Pipette (for adding water)

of H 2O2 present in a solution. The amount will be the baseline for activities C and D. The purpose of activity C is to determine the rate at which H2O2 spontaneously decomposes when exposed to room temperatures and ambient light for 24 hours. The purpose of activity D is to determine the rate at which catalase decomposes H2O2. After adding H2SO4 for different time lashes‚ etc.‚ the resulting data will be graphed at which the catalase decomposed by catalase. Background: The four different

This chemical reaction is represented by the formula: 2 H2O2 → 2 H2O + O2 (gas) Hypothesis: If the chemical reaction‚ H2O2 decomposition‚ is catalyzed by an enzyme‚ then the rate of the chemical reaction will increase.

peroxide (H2O2) is the simplest peroxide (a compound with an oxygen-oxygen single bond). It is also a strong oxidizer. Hydrogen peroxide is a clear liquid‚ slightly more viscous than water. In dilute solution‚ it appears colorless. Reactions Decomposition Hydrogen peroxide decomposes exothermically into water and oxygen gas spontaneously: 2 H2O2 → 2 H2O + O2 This process is thermodynamically favorable. It has a ΔHo of −98.2 kJ·mol−1 and a ΔS of 70.5 J·mol−1·K−1. The rate of decomposition is dependent

Enzyme Catalase under optimum conditions‚ speeds up the decomposition of hydrogen peroxide The students have studied that Hydrogen peroxide is a jeopardy to metabolism if it’s not obliterated. Enzymes are proteins produced by living cells of that act as catalysts which affects the rate of biochemical reaction by speeds up the breakdown of hydrogen peroxide into water and oxygen gas. The students have formed a hypothesis toward this experiment. If the speed of decomposition of hydrogen peroxide is related t
