thing in automotive fuel may very well be hydrogen. Automakers rapidly are closing in on making hydrogen fuel cell vehicles an everyday fact of life‚ with several test models set to debut over the next few years. Hydrogen fuel cells to power vehicles are desirable‚ experts say‚ because hydrogen is a renewable fuel that can be used to create electricity to run cars. A chemical reaction between oxygen and hydrogen produces the electric power‚ and when pure hydrogen is used‚ the only emission from the tailpipe

Enzyme Lab 6 03/13/2013 Report by Mary Jo Anthony I. Introduction II. Materials and Methods III. Results IV. Conclusion and Discussion Introduction Background Information: This lab allowed us to study chemical reactions and how catalysts will affect the rate of these reactions. The reaction we studied is the breakdown of hydrogen peroxide to water and oxygen and it is vital to life. The molecule hydrogen peroxide is a molecule that is toxic

constantly metabolizing which creates an extreme number of hydrogen peroxide; therefore‚ if the cell environment is either too acidic or too basic‚ the action of catalase can be inhibited which can cause the hydrogen peroxide to destroy our cells. In addition to catalase‚ there are also many enzymes that are the most efficient when surrounded by a pH of 7. However‚ there are some enzymes such as pepsin‚ who work under acidic environments (Biochemistry Lab Manual‚ 2003). The environment that surrounds our

catalase‚ which accelerates the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase and measure the rate of activity under different conditions. The laboratory was also conducted in association with a second laboratory that measured the effects of an inhibitor on the enzymes. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Each lab was assigned to a group A‚ B‚ C and D in

THE EFFECT OF HYDROGEN BONDING ON RESISTING FLOW Design Investigating a factor affecting the viscosity of a mixture of liquid Research Question The effect of hydrogen bonding on resisting flow of five different liquids Background Theory Viscosity is the resistance of a fluid to flow‚ either within itself‚ or to moving past an objects moving through it. A liquid with high viscosity is thick and flows slowly. A liquid with a low viscosity is thin and flows quickly. Different liquids

it fun‚ exhilarating‚ and decently scary you also have to think about the scientific principles. As these will all be defined by Oxford’s dictionary. One of the most common scientific principles is kinetic energy. Kinetic energy is energy that an object possesses by virtue of being in motion. Kinetic energy increases as motion increases during the roller coaster ride. Potential energy is the energy of a body or a system with respect to the position of the body or the arrangement of particles in the

When hydrogen gas comes in close contact with fire‚ it generates a loud noise similar to a popped piece of popcorn and it blows out the flame. 2. Oxygen B. When manganese reacts with H2O2 small bubbles form around the pieces of manganese and carbonates the whole solution. E. When I put the glowing toothpick in the oxygen gas it caused

The purpose of this lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions;
