affecting the catalytic decomposition of Hydrogen peroxide Please refer to the additional files for tables/graphs. Aim- The purpose of this investigation is to investigate how certain factors affect the catalytic decomposition of Hydrogen peroxide. I will investigate the effect of altering the mass of catalyst used on the rate of the decomposition of Hydrogen peroxide. Introduction- The decomposition of Hydrogen peroxide is a process by which Hydrogen peroxide decomposes into water and Oxygen

defined as a group of psychotic disorders involving major disturbances in perception‚ language‚ thought‚ emotion‚ and behavior; the individual withdraws from people and reality‚ often into a fantasy life of delusions and hallucinations. Schizophrenia means ’split mind‚’ but the name really refers to the fragmenting of thought processes and emotions found in schizophrenic disorders. Schizophrenia is characterized by psychological disturbances in five areas; perception‚ language‚ thought‚ affect (emotions)

Changes in the Atmosphere Causing Multicellularity About 2.5 billion years ago‚ oxygen began slowly to accumulate in the atmosphere‚ as a result of the photosynthetic activity of the cyanobacteria. Those prokaryotes that were able to use oxygen in ATP production gained a strong advantage‚ and so they began to prosper and increase. Some of these cells may have evolved into modern forms of aerobic bacteria. Other cells may have become symbionts with larger cells and evolved into mitochondria

the most abundant thing in the universe? Hydrogen is the answer! Now with a little bit more refining it will be. Good morning fellow students today I will be talking about hydrogen powered vehicles. Firstly‚ some terms need definition.Hydrogen- a colourless‚ odourless‚ flammable gas which is the lightest and simplest of all known elements.Vehicle- A device or structure for transporting persons or things. Secondly‚ now to explain the ways to use hydrogen as a fuel. The first way is called electrolysis

OF CATALASE ON HYDROGEN PEROXIDE The aim of the experiments is to see if increasing the surface area of the enzyme Catalase‚ affects the relative activity of the substrate Hydrogen peroxide. Then to observe and measure the effect the Catalase has on the chemical breakdown of the hydrogen peroxide. My theory is if you keep increasing the surface area of Catalase‚ the more active sites are available to join with the substrate causing an increase in the breakdown of the hydrogen peroxide producing

Hulsey Fire Tech 107 15 November 2015 Hydrogen Peroxide According to Lee Lerner‚ (2008)‚ “Hydrogen Peroxide is most widely found in homes in brown bottles containing three percent solutions (3% hydrogen peroxide and 97% water).” Lee Lerner (2008) writes “Hydrogen Peroxide is a colorless liquid that mixes with water and is widely used as a disinfectant and bleaching agent.” Hydrogen Peroxide is used in many different ways and has different hazards. “Hydrogen peroxide is a strong oxidizing agent used

Reaction of catalase with hydrogen peroxide AIM: I aim to find the rate of reaction between catalase and hydrogen peroxide. Enzymes such as Catalase are protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. Each enzyme just performs one particular reaction so they are all very specific. Catalase enzymes found in living cells e.g. in yeast‚ potato or liver‚ speed up (in our case) the breaking down of hydrogen peroxide. The lock and key analogy…

2.3.2 Counter Ion “Most bacterial cell walls are charged with a negative charge‚ so most antibacterial polymers must be charged with a positive charge to facilitate the adsorption process. The composition of the counter ion‚ or polymer-linked ions‚ is used to balance the charge‚ it also affects the antibacterial activity. The counter ion has positive charge‚ which is a strong ion-pair with the polymer will inhibit the antibacterial activity because it will prevent the polymer from interacting with
