Chemistry Catalyst Report Aim I am trying to investigate the effect of the mass of magnesium dioxide used on the speed of the reaction of 2H2O2(aq) 2H2O(l) + O2(g). I hypothesize that the speed of the reaction is proportional to the rate of decomposition. Independent Variable The mass of MnO2 used Dependent Variable The rate […]
Enzyme Activity Lab Hypothesis: Are enzymes reusable? Yes, enzymes are reusable. Which of the following do you think contain catalase? [Manganese dioxide, chicken meat, apple, carrot, potato, or chicken liver] I think that the manganese dioxide, apple, and carrot contain the catalase. Would grinding the materials affect enzyme activity? I think that grinding the materials […]
For this reaction the heat of dissociation is equal to the HO-OH bond energy. Since it is difficult to measure the heat of this reaction directly, you will use Hess’ Law to determine DHdis. Hess’ Law states that since the enthalpy is a function of state, it does not matter how the final state is […]
At the most basic level, enzymes are biological catalysts. They are proteins, meaning that they are polymers of amino acids. Their tertiary structure gives them a globular form due to the bonding present in the molecule. Many types of bonds hold the structure together and in the right shape. They strongest of these are the […]
Catalase is a red, crystalline enzyme that consists of a protein complex with haematin groups and catalyses the decomposition of hydrogen peroxide into water and oxygen: 2H2O2 –> 2H2O + O2Hydrogen peroxide is a powerful oxidising substance. It is formed inside cell organelles called the peroxisomes, during the breakdown of purines. Peroxisomes help to oxidise […]
It has the following equation: 2H202 (l) 2H20 (l) + 02 (8) This reaction does occur spontaneously at room temperature with the presence of ltraviolet light; however only very slowly. It occurs far faster when a catalyst is used. Catalysts are substances that speed the rate of a reaction without getting involved in the reaction […]
First recognized as a chemical compound In 1818, hydrogen peroxide Is a clear, colorless llquld most often used for cleaning or disinfectlng(Brltannlca, 2013). Since pure hydrogen peroxide Is unstable, It Is found In stores as an aqueous solution. The chemical formula for hydrogen peroxide Is H202 which means there are two hydrogen atoms and two […]
The main properties of cleaning agents One of the most important properties of cleaning agents is their ability to act as cleaning agents during the cleaning process. A bleaching agent in chemistry is any cleaning agent that has the ability to remove coloured stains in clothes or the substance subjected to cleaning (Ebbing & Gammon […]
Introduction In this week’s lab experiment, the rate of decomposition of hydrogen peroxide forming oxygen gas will be observed and studied. Since the rate of a chemical reaction is dependent on two things; the concentrations of the reactants and the temperature at which the process is performed, the rate can be measured at which a […]
