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

Prashant Zanwar University of Central Florida I. Introduction To Maglev Technology And Application 1.1 Principle of Maglev System Maglev is a system in which the vehicle runs levitated from the guideway (corresponding to the rail tracks of conventional railways) by using electromagnetic forces between superconducting magnets on board the vehicle and coils on the ground. The following is a general explanation of the principle of Maglev. fig. 1.1 1.1.1 Magnetic Levitation The "8" figured levitation

contribute to the outcome‚ but a car cannot run on no fuel‚ just like our fuel for the 400m race is the energy systems. There are 3 energy systems that we classify‚ from the amount of work we are creating for ourselves. These consist of ATP‚ Lactic Acid‚ and Aerobic capacity In the 400m though‚ we use two of the three energy systems. The first‚ and the most valuable of all is Adenosine Tri phosphate‚ or simply‚ ATP‚ which is the immediate usable form of chemical energy for muscular activity. This is one

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…

relationship between moles evolved and consumed. This can be demonstrated by measuring the hydrogen gas evolved by performing a chemical experiment when hydrochloric acid reacts with the magnesium. The formulated reaction includes; Mg + 2HCl → H2 + Mg2+(aq) + 2Cl- (aq) The major findings contributing to the experiment is being able to determine and distinguish what moles have evolved thus being the hydrogen moles evolved allowing the magnesium to be consumed within the reaction.

Abstract The decomposition of hydrogen peroxide (H2O2) in a whole and diced wedges by with The enzyme catalase was observed. The catalase was able to break down the hydrogen peroxide In the diced banana wedge better than the whole banana because after the banana was diced that Increases the surface area allowing the breakdown to flow. The effects of temperature on enzyme In a liver sample were observed under iced‚ boiling‚ 37 degrees‚ and room temperature Conditions. The enzymes became completely

Chemistry 2500- Exercise C4 The Emission Spectrum of Atomic Hydrogen Objective The purpose of this lab was to calculate an experimental value for the Rydberg constant and then the ionization energy for the hydrogen atom. These values will be obtained by using a prism spectrograph to measure the wavelength value for a section of the visible line spectrum of atomic hydrogen. Theoretical Background When H+ combines with an electron it forms it’s excited state‚ H. This excited atom
