Hydrogen Essays

Hydrogen since the beginning of time has always meant a significant amount of importance to science. Hydrogen for those who do not know hydrogen is the most abundant element in the universe. Nearly nine out of every ten atoms in the universe are hydrogen atoms. Hydrogen is with oxygen and silicon in abundance in the universe making them the big three. Hydrogen is the simplest of all elements. It only consists of one proton and one electron. Hydrogen was first discovered in seventeen sixty-six

negative poles by what amounts to static electricity. This electrostatic attraction is termed a hydrogen bond. It is about 20 times weaker than the H – O bonds within any one water molecule, but still gives rise to considerable, transient adhesion, which packs the water molecules closely together in the liquid state. In contrast, as the temperature falls below about 4 ° C and ice begins to form, the hydrogen bonds between the molecules become longer lived. They eventually settle into a rigid, rather

Hydrogen chloride has a very powerful smell. It is in the form of a gas but only when it is at room temperature which is approximately 25 Celsius and when the pressure is high. When you add water to hydrogen chloride then it breaks down into small pieces which are known as dissolving. The solubility of hydrogen chloride is very high this means that it can dissolve in water quickly because it dissolves many times in its own solution (the gas form of hydrogen chloride). It is very soluble because

catalytic decomposition of hydrogen peroxide Research question: How will varying the concentration of hydrogen peroxide affect the rate of reaction measured by collecting the amount of oxygen produced figure 1 shows how catalyst provide alternate pathways Background: For my internal assessment I will be investigating the catalytic decomposition of hydrogen peroxide using manganese(IV)oxide( MnO2 ) as a catalyst. I will be testing how varying concentrations of hydrogen peroxide will affect its

Hydrogen Sulfide undergoes covalent bonding – where two or more non-metal atoms are held together by one or more shared pairs of valence electrons. The atoms forming a covalent bond must have a relatively equal attraction for electrons (electronegativity). Hydrogen has an electronegativity of 2.2 and sulfur of 2.58. Covalent bonds tend to also have low melting and boiling points due to weak intermolecular forces which break down quite easily (BBC, 2014). Substances that are bonded covalently are

study of the amounts of substances that are involved in reactions. For this experiment kinetics is a huge part of it. Kinetics is explained as the reaction speed and or rate of reaction. To observe these reactions made by having reactants, sodium hydrogen carbonate, NaHCO3 known as baking soda and acetic acid, CH3COOH that is vinegar being mixed together. The products were carbon dioxide, water, and sodium acetate. Because this reaction will be based on its speed according to the difference in temperature

Lab Report for the Seawater Chemistry Lab 1) The Strength of the Hydrogen Bonds Formed by Water Molecules a) Are the bonds formed by water molecules stronger or weaker than the bonds between molecules of other liquids? Hydrogen bonds formed in water are stronger than those of other liquids. b) What evidence have you seen that supports your belief? Describe observations from at least two different lab experiments. Hydrogen bonds in water are very strong because water has strong intermolecular

Exploring Issues in Electrochemistry: Lithium or Hydrogen? Unit 5: Electrochemistry SCH4U Yasmin Hashi May 14, 2018 Exploring Issues in Electrochemistry: Lithium or Hydrogen? Gasoline powered vehicles outnumber the amount of cars that are alternative powered. The combustion of fossil fuels like gasoline is considered a major source of air pollution and a contributor of climate change. Gasoline is an extremely flammable and very toxic liquid. This causes automotive experts to think that gasoline-powered

The purpose of this experiment was to analyze the rate of the catalyzed decomposition of hydrogen peroxide in regard to the effects of concentration and temperature. 2H2O2 (l) —I-—> 2H2O (l) + O2 (g) In part one of the experiment, catalyst KI was added to varying solutions of 3% hydrogen peroxide and DI water and the composition of hydrogen peroxide was observed. This was observed by collection the volume of oxygen gas produced during the decomposition, and measuring its volume. From that, volume

Toyota has taken up hydrogen powered cars. Hydrogen binds to almost anything, so before it can be used it must be separated. It’s also the most abundant element in the universe. You need a fuel cell to make a hydrogen powered car work. It combines with Hydrogen and takes up Oxygen. By doing that it will produce electricity. When Hydrogen is compressed it is very dense and easy to transport, that’s another positive factor towards this vehicle. Some folks think that it will carry energy and help to

following research question: "How does hydrogen bonding change in a solvent like Propanone, which is a Polar Aprotic solvent and water, a polar solvent are added separately into pure Alpha Hydroxy compounds like Glycerol, Ethylene Glycol, and Propylene Glycol by measuring the ΔH (Change in Enthalpy) changes by Calorimetry?” Aprotic solvents may have hydrogen atoms in the compound, yet they need O-H or N-H bonds, and along these lines, they are unable to frame hydrogen bonds with themselves.These solvents

examine the effects of Hydrogen Peroxide coming into contact with a catalase solution, in this experiment it was Calf Liver. As a result of the contact, oxygen gas was formed. Therefore, the collected data suggested the rate of reaction of the catalyse increases as the volume of Hydrogen Peroxide increases. This can be seen through the linear trend line that moves up in a positive direction, which shows that the relationship between the rate of reaction and the volume of hydrogen peroxide is positive

alternative to power cars is through the use of hydrogen fuel cells. Generally, this works through converting the chemical energy of fuel into electricity through a reaction between hydrogen (H) and oxygen (O). This works through a typical voltaic cell in which stored chemical energy produces electrical energy; the fuel cell is composed of two parts - an anode and a cathode. Hydrogen gas flows through the anode where a catalyst causes the hydrogen to separate into protons and electrons. The protons

The purpose of this experiment was to determine how the rate of the catalyzed decomposition of hydrogen peroxide is affected by concentration and temperature. In Part 1, the volume of oxygen gas was measured to determine the rate law of hydrogen peroxide. The volume of oxygen gas was measured because it is a physical property that is more easily observable, making the reaction easier to record and calculate. The reaction is second order, this can be determined because the sum of the exponents is

The environmental impact of a hydrogen powered economy The Production of hydrogen, how is it actually made?........ There are a number of ways that are used to generate hydrogen production, currently the main method is steam reforming from hydrocarbons such as natural gas. However is Hydrogen fuel efficient enough to replace fossil fuels in the future? Since the introduction of Hydrogen fuel to the world, scientists have been trying to improve this concept in many ways. A lot of support has been

renewable fuel. Hydrogen address the issue of sustainability, environmental emissions like releasing of greenhouse gases in our environment and energy security. Hydrogen is consider most suitable element to replace fossils fuels because it the only element which is found in the abundance in the universe and it burns clean without releasing any greenhouse effect and it is only producing water and has the highest density per unit mass. However, as like FOSSILS FUELS hydrogen is not a

Hydrogen bombs are more than 1000 times more powerful than the very common atomic bomb. The explosion is from nuclear fusion which is when hydrogen nuclei (plural of nucleus) are joined to form helium nuclei, releasing great destructive energy and radioactive fallout. When the nuclei combine there is a split second where there is nothing and then there is the explosion. An atomic bomb is the trigger or the smaller bomb of what sets off the hydrogen bomb. We have to be careful with the hydrogen bomb

If you conduct the catalyzed decomposition of hydrogen peroxide in a closed vessel, you will be able to determine the reaction rate as a function of the pressure increase in the vessel that is caused by the production of oxygen gas. If you vary the initial molar concentration of the H2O2 solution, the

The dependent variable is the rate of decomposition of water which is measured by the volume of hydrogen gas and oxygen gas in cm3 The independent variable is the voltage here as I increase it from 9-14 Room temperature was 24 rtp and I carried out the whole experiment in the same room. If the temperature increases the rate of electrolysis will increase
