PPT-Hydrogen and Oxygen

Information and Uses Unit 2 Mission to Mars Connection Hydrogen is the lightest and most abundant element in our universe Hydrogen does not exist by itself in nature Hydrogen exists as parts of compounds. Examples include hydrogen carbon dioxide argon helium and various halogenated hydrocarbons such as the Freons Almost any single constituent of a gas mixture can be measured providing its thermal conductivity differs from that of the other components & . Anaerobic Bacteria. Introduction. Bacteria can exist in a wide variety of environments, including environments that lack oxygen. . In fact, oxygen is toxic to some bacteria. This toxicity is usually due to the accidental formation . Both elements and compounds are pure substances. Compounds are made by chemically combining 2 or more elements (the only way to break down a compound is by another chemical change-they break into smaller compounds and elements). (Carbohydrates, Proteins, Lipids, Nucleic Acids). By – . Nevin. Varghese. Victor . Veras. Dapo. . Adegbile. Carbohydrates. Purpose. – used by cells to provide energy. Structure. – Composed of carbon, hydrogen, and oxygen with a ratio of about 2 hydrogen atoms and one oxygen atom for every carbon atom. 2.16. recall the gases present in air and their approximate percentage by volume.  . Air is a mixture of gases . which contains 4/5 nitrogen. 1/5 oxygen. 2.17. describe how experiments involving the reactions of elements such as copper, iron and phosphorus with air can be used to determine the percentage by volume of oxygen in air. Elements . from Stardust. . Elements from Stars. Scientists study the stars and our sun to understand how . elements (matter) . were created and why. . The sun is mostly made of Hydrogen (H).. H. PLASMA STATE. balanced chemical equations drill. Each of the following slides first gives you a word equation.. You must write the balanced chemical equation, with phases, then click ahead to check your work.. Each slide is numbered, so you can do some, come back and then do more.. Information and Uses. Unit 2 - Mission to Mars Connection. Hydrogen . Hydrogen does not exist by itself. in nature. Uses for hydrogen. Oxygen. Uses for Oxygen. Water (H. 2. O. ) . A water molecule is made up of one oxygen atom sharing electrons with two hydrogen atoms. . How do solar systems form?. B. Stellar Nurseries . C. A. How did the solar system form?. Astro. Comics Presents…. Long ago…. Nebula. Hmm…I am just moving around randomly.. Before Planets. A nebula is a cloud of dust and gas in space.. – anything that has mass and takes up space.. vocabulary. word!. atom. - The atom is the smallest unit of a substance that maintains the properties of that substance.. It is so small, it would take a million atoms lined up to equal the thickness of a human hair.. Peter Ota. Content Overview. Thermochemical Cycles. Heat sources for thermochemical cycles. Iodine-Sulfur cycle. Bromine-Sulfur hybrid cycle. Hybrid sulfur cycle. Conclusion. Thermochemical Cycles. Combine heats source with chemical reactions to split water into hydrogen and oxygen. OBTAINING CO. 2. FROM FERMENTATION PROCESS. Another source of CO. 2. is fermentation industry. If yeast is used, alcohol and CO. 2. are produced. Yield of CO. 2. varies with mode of fermentation.
