Hydrogen Essay

essential element is hydrogen, the first element on the period table (located under Group 1 as an alkaline metal) is composed of a single proton and electron; therefore having an atomic number and atomic mass of 1 and electron configuration of 1s1. In fact, hydrogen is the lightest, simplest and most commonly found chemical element in the universe (it makes up about 90% of the universe by weight). Interestingly enough, the heavier elements on the periodic table were either made from hydrogen or other elements

Hydrogen Alpha & Astronomical spectroscopy Solar telescopes are able to take detailed photos of the sun, as they only allow specific wavelengths. This wavelength is otherwise known as hydrogen alpha (656.281 nm) which marks the transition of electrons around the hydrogen atom, from the third leveled to the second leveled. Using the Bohr model of the hydrogen atom, the transition of an electron from n=3 to n-2, releases a fixed amount of energy which radiates at that specific wavelengths. This allows

Hydrogen and Fuel cells Renewable energy Hydrogen and fuel cells are not technically renewable energy although they are everywhere and don't cause much pollution. With hydrogen, it can be used as fuel and the only emission is water. By using hydrogen there can be a large reduction in green house gases and air pollution. Plus the hydrogen can be used in the fuels cells to power electric motors or batteries for electricity. If your wondering what fuel cells is, there pretty much batteries, or what

the minds of many. Hydrogen is the most abundant element in the universe and has been present since the beginning of time. Hydrogen is the smallest element in the universe, hydrogen consists as a diatomic, gaseous molecule with a single proton and a single electron. Hydrogen does not exist in its pure form on the planet, but it is present as a compound in molecules like water, glucose, natural gas, and even oil (Busby). Because it is found in such a variety of sources, hydrogen is the perfect power

Abstract In this experiment, microscale quantities of hydrogen and oxygen were generated to test their explosive nature both separately and in mixtures of various proportions in order to identify the mixture with the most explosive energy, via a pop test that measured relative loudness, thus determining the optimal ratio for their combustion reaction to give water, and determine a mole ratio for the reaction in a balanced equation. Each gas mixture was then tested for power as fuel through the launching

ball of plasma a star? It’s because the high-powered synthesis of hydrogen into helium in its core that makes our star shine the brightest in the Milky Way. But just 100 years ago, we knew so littler about our Sun, scientists didn’t even know it’s true composition. It wasn’t until the great works provided by Cecilia Payne-Gaposchkin, who discovered that the composition of our Sun was the abundance of hydrogen. This helped prove hydrogen as the most abundant element in the Universe and of course changed

Tetrahydrofuran | 72.1 | .889 | 66 | Irritant | Hydrogen Peroxide | 34.0 | 1.135 | 152 | Corrosive, harmful | 1-octanol | 130.2 | .824 | 195 | Irritant | 2-octanol | 130.2 | .819 | 160 | Flammable | Discussion: Hydroboration-oxidation is a one step, conservative organic reaction that converts an alkene into a neutral alcohol by the addition of water across the double bond. This reaction is anti-Markovnikov, which leads to the hydroxyl

After completing the lab, we will be able to identify covalent, ionic, and hydrogen bonds. Hydrogen bonds are the weakest between all the three types of bonds we will be observing and it occurs between hydrogen and oxygen atom or nitrogen atom; hydrogen bonds are a type of dipole-dipole bond. A dipole-dipole interaction occurs because of polar molecules. We should know that the bond between hydrogen and oxygen in a water molecule is covalent. Another example, of covalent bond is the bond between

Based on the mass of the products in the beaker after the decomposition reaction which was 1.98g, the correct decomposition reaction is when the sodium hydrogen carbonate decomposed into sodium carbonate, water vapor, and carbon dioxide gas. Since the water vapor and carbon dioxide would have escaped the beaker during the reaction, sodium carbonate would have been the only remaining product in the beaker. Sodium carbonate is the product remaining in the beaker because the theoretical yield of the

can be used for vehicles. Hydrogen is considered to be one of the most promising ones because hydrogen it can provide an unlimited amount of resources, while petroleum had a limited amount of consumption. There are other kinds of alternative fuels such as Ethanol, Propane, Natural Gas, Biodiesel, and Electricity. However, using hydrogen is one of the best option we do not have to worry about fuel shortage or polluting the environment. This is because hydrogen can be obtained from organic
