Hydrogen Liquid And Its Uses

Experiments 2-1 and 2-2 study the production of hydrogen gas by different chemical reactions. By using a hydrogen gas collection apparatus and the principles of chemistry, we were able to evaluate the data and reach our goal. Experiment 2-1 uses zinc, magnesium and aluminum and how much hydrogen gas they produce to predict the volume of hydrogen gas produced for different masses of each metal. In this experiment we see that each metal has an increasing amount of hydrogen gas as mass goes up, however each metal had different amount of hydrogen gas for the same mass. Zinc produced the least amount of hydrogen gas, then increasing with magnesium, and aluminum produced the highest amount. The

Hydrogen gas is only slightly soluble in water. It is not poisonous. Hydrogen has three isotopes called protium, deuterium, and tritium. Tritium is radioactive and has been uses in the hydrogen bomb. In the laboratory, hydrogen can be produced by the electrolysis of water. Hydrogen combines directly with several of the most active elements, but most hydrogen compounds are made by indirect methods. Mixtures of hydrogen and oxygen explode violently when ignited by a spark. When there is air or oxygen with hydrogen’s presence, hydrogen burns with a hot flame and forms water. Chlorine burns in hydrogen and forms a colorless gas called HCl. Ammonia, whose symbol is NH3, is made by combining hydrogen and nitrogen. Other hydrogen compounds prepared indirectly include hydrogen peroxide (H2O2), acetic acid (CH3COOH), and ethyl alcohol (C2H2OH). Hydrogen also combines directly with a variety of compounds. In the presence of a catalyst at high temperature and pressure, hydrogen combines with carbon monoxide to form methanol or wood alcohol (CH3OH). Hydrogen also unites with liquid fats to form solid fats through a process called hydrogenation. Many hydrogen compounds, such as ammonia, ethyl alcohol, and hydrogen peroxide, have extensive industrial uses. Hydrogen is also a good reducing agent and is used to recover some metals from their compounds. Hydrogen’s ability to produce heat when united with oxygen makes it a good fuel or fuel enhancer. They Hydrogen Fuel cell is

This source mainly concentrates on the use of hydrogen fuel cells as an alternative to the United States dependency on foreign oil. It elaborates on the negatives of our countries reliance upon external sources for the vast majority of our power production needs, and suggests that hydrogen fuel cells are the answer to a sustainable energy future. The author is a writer for CQ Researcher who concentrates on energy, environmental, and defense issues. While the article is mainly geared toward individuals interested in the automotive industry and the applications of hydrogen fuel cells in vehicles, it does an excellent job of contrasting oil based

Out of the many metal hydrides, combination of magnesium hydride with a 7.6wt% storage capacity has sparked the most interest. Using metal hydride to store hydrogen requires an absorption step and a desorption step. Metal hydride is formed by a hydrogen molecule (H2) being adsorbed on the surface, where it is decomposed into individual hydrogen atoms (H). These hydrogen atoms then diffuse into the bulk of the metallic material and finally form a metal

With proper handling, hydrogen is as safe as any other fuels such as gasoline, diesel or natural gas – and in some instances even safer. For decades, codes and standard of handling hydrogen have been implemented and safe system designs have been developed. Now hydrogen is produced, shipped, distributed and used safely worldwide for the use in everything from welding to hydrogenated peanut butter. Over 50 million tonnes of hydrogen are produced annually worldwide. Hydrogen is the most common element in the universe, and it’s also the lightest. This means that if there is a leak in a storage tank, the hydrogen rises and diffuses quickly into non-flammable

Even though hydrogen as a fuel seems to answer every problem we want it to; it also has setbacks. Although we have the technology now to bring us an endless supply of hydrogen fuel we do not have the storage or infrastructure capabilities for it. “Hydrogen

Scientists have also figured out how to harness solar energy, using electricity from photovoltaic cells to yield hydrogen that can be later used in fuel cells. But hydrogen has failed to catch on as a practical fuel for cars or for power generation in a world designed around liquid fuels.

13. What is hydrogen fusion? This process is sometimes called “hydrogen burning”. How is hydrogen burning fundamentally unlike the burning of a log in the fire place? Hydrogen Fusion is a thermonuclear process which produces the Suns energy. During the process four hydrogen nuclei release energy when they fuse together in order to create a single helium nucleus (334). Hydrogen burning is unlike the

Hydrogen fuel cell vehicles are an optimal solution to the continuously growing environmental problems of conventional vehicles. The use of hydrogen as a type of fuel can cleanse our atmosphere by only emitting water as a form of tailpipe exhaust, deterring the deterioration of the health of all organisms. And simply with time, knowledge, and a little perseverance, we can all save the world, one vehicle at a

There are many elements that occur naturally on earth that can be put to good use to help with everyday life. Some of these elements, however, can cause harm if proper control is not taken when working with the element. Hydrogen is one such element that can be beneficial if used correctly and catastrophic if not.

As time in the future comes near, hydrogen could join electricity as an important energy carrier. An energy carrier is able to transport and deliver energy in a useable form to consumers. There are renewable energy sources such as the sun and wind, but they can’t produce energy all the time. With hydrogen being a fuel cell, it has a higher efficiency than diesel or gas engines. Most fuel cells are able to operate without making sound, compared to central combustion engines. Therefore they’re perfectly convenient to be usable in buildings such as

     Cars powered by hydrogen get better gas mileage. They can go double the distance or even triple the distance of the car with the best gas mileage on the market. The cars can’t go as fast as cars can today, but they can get very close. Toyota is the biggest supporter of hydrogen powered vehicles. They already have working hydrogen cars in other countries on the road. They have many prototypes ready and waiting for the US.

In order to understand the why behind the need to change from fossil fuels to hydrogen power, it is necessary to understand what that power is and how it works. Hydrogen is the most abundant and simplest element on earth. It is most commonly found as part of water. In its pure gaseous form it is extremely light, but when ignited in this state releases a large amount of energy in an explosion. In this violent reaction the hydrogen combines with free oxygen molecules in the atmosphere and creates water vapor. This is similar to the way gasoline is combined with air and ignited in an internal combustion engine in the cars used today and like with gasoline, the combustion of hydrogen has risks. In addition to the risk, some of the energy released in the reaction is lost in the form of sound and heat. As an alternative to burning, these same gases can be combined with the use of catalysts to extract the free electrons produced as liquid water is formed(Popovici and Hoble Dorel). Using cables connected to a fuel cell such as this, those electrons go through a circuit, generating electricity. This is more efficient than combustion because less energy is wasted in the form of sound and heat. Going further, greater efficiency for this reaction can be had the lower the temperature it is allowed to take place at, with 83% power at 25◦C(77◦ F)(Popovici and Hoble Dorel). As fuel cells are created with better heat management and
