that Affect the Rate of Reaction of the Decomposition of Hydrogen Peroxide Emilio Lanza Introduction- In this experiment‚ the rate of reaction‚ calculated in kPa sec-1‚ of the decomposition of hydrogen peroxide will be investigated to see how the change in concentration of hydrogen peroxide and the change in temperature affect the rate of reaction. The data will be collected by measuring the gas pressure. The product of Hydrogen Peroxide is oxygen in a gas state thus it is mandatory to use the

Kinetics of the Decomposition of Hydrogen Peroxide Lab 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 reactant disappears or at which a product appears. When measuring the rate‚ the rate law will be applied. The

kind of role does hydrogen peroxide and a liver have in their chemical reaction? In the experiment‚ we saw they had a reaction‚ but completed further tests to determine whether they changed after the reaction. Hydrogen peroxide is chemically changed into water and the liver is broken down in the reaction. In the experiment‚ a fresh piece of chicken liver was put into a test tube filled with 3% hydrogen peroxide. We knew a reaction was taking place because the hydrogen peroxide started to foam and

because it can cause hazard for the humans and possibly to the environment‚ the hydrogen peroxide is now as an alternative to replace formalin for a common treatment for parasites (Pedersen and Flemming‚ 2010). Graslund et al‚ 1 (2003) showed that the hydrogen peroxide acts as chemical that served several purposes such as to eliminate bacteria‚ parasite and also algae in shrimp farming. However‚ the hydrogen peroxide still can be hazardous for the health of farmers (Boyd‚ 1999) and also affect

An Investigation on the rate of reaction of the enzyme Catalase on the substrate Hydrogen peroxide. Plan Aim: To investigate the rate of the effect of Catalase on hydrogen peroxide. Introduction This investigation will be carried out to investigate the rate of reaction of the enzyme catalase on the substrate hydrogen peroxide. Enzymes are biological catalysts‚ which speed up the rate of reaction without being used up during the reaction‚ which take place in living organisms. They do this by

To Meat or Not To Meat William D Jordan DeVry University To Meat or Not To Meat It seems like the United States of America is quickly becoming a nation of dieters. Every day more people become increasingly cautious about what they eat. Magazine racks everywhere are full of how this celebrity lost weight‚ or some new secret dieting tip will give the reader the body of their dreams. Some of these methods‚ when looked into‚ just take old fads that have been tried in the past and put a new spin

Meat or no meat – that is the question. According to Socrates‚ “The best diet consists of bread‚ olive oil‚ cheese‚ fruit‚ vegetables and moderate amounts of wine‚” but in American society today eating meat is a large part of most diets. For the average person‚ changing their diet would be required to follow the wisdom of Socrates‚ and since change is always difficult‚ finding an adequate motivation to carry it out is critical. Although there is an ongoing debate whether or not the humans benefit

Abdulaziz Design Lab Report Research Question: How is the rate of yeast fermentation of 7.5g of yeast affected by using different companies of yeast (Bakon Yeast Inc.‚ Lake States Yeast LLC‚ Lesaffre Yeast Corp‚ Red Star Yeast Company‚ and Minn-Dak Yeast CO Inc.)? Background Information: Yeast is a fungal microorganism that is used to manufacture mainly bread and beer. It reproduces rapidly. Fermentation is the process by which yeast takes in sugar and releases alcohol and carbon dioxide. Fermentation

Factors Affecting the rate of Hydrogen Peroxide degradation using Catalase Introduction An enzyme is a globular protein which functions as a catalyst that speeds up the rate of a reaction without being consumed in the reaction. An enzyme-catalyzed reaction occurs when a substance called the substrate binds onto the active site of the enzyme. This joining allows for a reduction in the activation energy and the reduction in activation energy helps the reaction to occur at a quicker rate. Enzyme

In the yeast discovery lab we had to decided what the outcome would be then perform the experiment. The experiment was done during class time‚ so everyone’s results would be the same. There were four bottles with warm water in them and to those bottles were added yeast. Then to one of each bottle there was added sugar‚ corn syrup‚ corn starch. To the fourth bottle there was only yeast added and used as a control group. Balloons were then stretched onto the top of the bottles to catch any gas the
