Premium Natural gas Fuel cell Hydrogen
Hydrogen has a high specific energy‚ high flame speed‚ wide range of flammability‚ and clean burning characteristics which suggest a possibility of high performance in internal combustion engines (ICE). These attributes have been realized for more than half a century since the onset of hydrogen engine development. In the early 1990s‚ FSEC conducted research on using hydrogen in an ICE. This work resulted in the development of a mixed fuel called HYTEST. Today‚ automobile manufacturers and DOE continue

Hydrogen Summary * This is how hydrogen fuel cells work: 1. Gas stored in tanks 2. Atoms reach anode 3. Become hydrogen ion and a free electron 4. Ion goes through electrolyte layer 5. Hydrogen ion passes‚ but free electron does not 6. Free electron runs through external circuit from anode (-) to cathode (+) 7. Current of electrons creates electricity 8. Hydrogen ion enters cathode and combines with oxygen to become water which is better for the ecosystem because

bombs and hydrogen bombs. The hydrogen bomb is the most powerful‚ destructive bomb of all. In this essay I’m going to give a brief history of the hydrogen bomb‚ the chemistry behind the bomb‚ and how much destruction the hydrogen bomb can do. After the Soviet Union’s atomic bomb success during the cold war‚ the U.S wanted something bigger and stronger. In 1950‚ President Harry S. Truman announced work on the hydrogen bomb. A group of scientists led by Edward Teller created the first hydrogen bomb in

Enthalpy‚ represented by the sign ∆H in kJ/mol‚ is the heat change in a reaction. It shows whether how much heat is released or absorbed during the reaction. If the reaction is endothermic‚ the enthalpy would be positive and if the reaction is exothermic‚ the enthalpy would be negative. During a chemical reaction‚ which consists of breaking and creating bonds‚ heat is either absorbed or released. In this lab‚ the reaction uses the disassociation of an ionic compound ammonium nitrate shown in the

Calorimetry: Enthalpy of Neutralization Introduction: The purpose of this lab experiment was to determine the molar concentration of the unknown HCl by using a coffee cup calorimeter. A coffee cup calorimeter is made of Styrofoam cups with a thermometer that is placed from the top and into the calorimeter to measure the temperature as the reaction happens. The Styrofoam cup used for the calorimeter creates an isolated system as it acts as a heat insulator between the cup and the surrounding

SCH4U 03/04/13 Hydrogen Bonding Purpose: The purpose of this investigation is to test the concept of hydrogen bonding. Hypothesis: Given the concept of hydrogen bonding I predict that the bulky glycerol molecules limits the number of possible hydrogen bonds. If water is mixed with glycerol should make it possible for water to form many hydrogen bonds with the glycerol molecules‚ causing it to become a exothermic reaction. Because glycerol has more possibilities for hydrogen bonding I believe

<b>Thesis Statement</b><br>The hydrogen bomb is a nuclear weapon in which light atomic nuclei of hydrogen are joined together in an uncontrolled nuclear fusion reaction to release tremendous amounts of energy. The hydrogen bomb is about a thousand times as powerful as the atomic bomb‚ which produces a nuclear fission explosion about a million times more powerful than comparably sized bombs using conventional high explosives such as TNT.<br><br><b>The Hydrogen Bomb</b><br>The Atomic Bomb Was A Essential

investigation: The speed of a metal carbonate breaking down depends on where the metal is in the reactivity series. The more reactive a metal is the slower it takes for it to breakdown. The less reactive a metal is it breaks down faster. Explain the hypothesis using scientific ideas: The metal carbonate which is lower in the reactivity series such as copper can thermally decompose much faster because it is the least reactive metal so its an unstable carbonate and the bonds are much weaker. So
