Road Salt And The Environment
1,465 wordsAs awareness for pollution increases, other less noticed types of pollution are recognized. Almost everyone knows about toxic waste and carbon dioxide pollution, but not many people have heard of salt pollution. Salt pollution has been on the increase since the evolution of the automobile. With more pressure on government agencies to keep the highway clear and safe, an increase in the use of salt has developed. It is important to understand why salt is used and how it work as well as the environ...

Water Can Travel Shale And Sandstone Erosion
1,789 wordsWATER: IT MOVES THE WORLD Water does move the world, but not always in a noticeable or dramatic way. Erosion is a key element in making the world possible to live in. Erosion forms the valleys, literally dissolves solid rock, moves 3 ton boulders, and builds bridges. Water is the most abundant and therefore most powerful resource on the planet. Although water creates landmarks the size of the Grand Canyon, man cannot see the process, only the result. RAIN EROSION According to Rain Erosion: graph...

Dry Ice Petri Dishes
1,905 wordsA particle cloud chamber is a device that makes visible to the human eye the presence of certain particles and cosmic rays. This paper will discuss the process in which a successful chamber prototype was developed. This paper will also discuss how the chamber utilizes the properties of a supersaturated environment to detect these particles. Finally, plans for the future development of a larger model to study the charge and energy of particles through the use of a magnetic field is presented. The...

Electron Transport Hydrogen Ions
778 wordsElectron transport is the last phase and most important phase of cell respiration. It accounts for most of the ATP made in cell respiration. Cell respiration makes a total of thirty eight Atp's, two from Glycolysis, two from the Krebs cycle and thirty four from electron transports. Electron transport takes place after Glycolysis and the Krebs cycle. Glycolysis and the Krebs cycle make their ATP through substrate level Phosphorylation while electron transport makes its ATP through oxidative phosp...

Sulfuric Acid Sodium Hydroxide
1,751 wordsAcid Rain Written by: Ali Right Introduction Acid rain has become an environmental concern of global importance within the last decade. With the increasing environmental awareness of the "unhealthy" condition of our planet earth the concern about acid rain has not lessened. In brief, acid rain is rain with pH values of less than 5. 6. When dealing with acid rain one must study and understand the process of making Sulfuric acid. In this project we will take an in depth look into the production of...

Carbon Dioxide Hydrogen Ions
1,424 wordsPhotosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules. Photosynthesis powers almost all trophic chains and food webs on the Earth. The net process of photosynthesis is described by the following equation: 6 CO 2 + 6 H 2 O + Light Energy = C 6 H 12 O 6 + 6 O 2 This equation simply means that carbon dioxide from the air and water combine in the presence of sunli...

Permeable Membrane Semi Permeable
781 wordsOsmosis is the flow of water through a semi permeable membrane that blocks the transport of salts or other solutes through it. It is also defined as the net movement of water from an area of high concentration to a region of low concentration. Osmosis is a fundamental effect in all biological systems. When two water volumes are separated by a semi permeable membrane water will flow from the side of low solute concentration to the side of high solute concentration. If external pressure is applied...

Molecular Biology Membrane Potential

This classification is not definitive in including all proteins, since there may well be other examples that span the membrane with different numbers of anchor chains. The structure of proteins varies greatly. The first factor affecting structure is the proteins function, but equally important is the proteins location, a...

Electron To Form Covalent Bond Bonds
446 wordsChemical bonds are what make up the world. In bonds, elements are held together and form compounds that may have new physical and chemical properties. There are two main kinds of bonds, they ionic and covalent. In bonding the goal of the atoms involved is to reach a level of stability with less energy. In order to reach the epitome of stability, as in the case of noble gases, an atom strives to complete its outer shell. Either losing or gaining electrons may do this, which concludes in an ionic ...

Nucleic Acids Double Helix
1,905 wordsDouble Helix A review of Watson, James D. The Double Helix. New York: Atheneum, 1968. James Watsons account of the events that led to the discovery of the structure of deoxyribose nucleic acid (DNA) is a very witty narrative, and shines light on the nature of scientists. Watson describes the many key events that led to the eventual discovery of the structure of DNA in a scientific manner, while including many experiences in his life that happened at the same time which really have no great signi...

Internal Combustion Engine Hydrogen And Oxygen
2,006 wordsToday many Americans face a lot of economical and environmental challenges. There is pollution in the air, water, and even lying on the ground all around them. Oil and gasoline products derived from petroleum are skyrocketing in price. Brownouts and blackouts are occurring in heavy power usage areas in the United States. What do these problems all have in common; a common solution: Fuel cell technology. A fuel cell is as defined by Webster is an electrochemical generator that produces direct cur...

Negatively Charged Positively Charged
571 wordsFusion reactions are inhibited by the electrical repulsive force that acts between two positively charged nuclei. For fusion to occur, the two nuclei must approach each other at high speed to overcome the electrical repulsion and attain a sufficiently small separation (less than one-trillionth of a centimeter) that the short-range strong nuclear force dominates. For the production of useful amounts of energy, a large number of nuclei must under go fusion: that is to say, a gas of fusing nuclei m...

Acid Rain Plant Growth
767 wordsPhosphates may be Untitled Phosphates may be created by substituting some or all of the hydrogen of a phosphoric acid by metals. Depending on the number of hydrogen atoms that are replaced, the resulting compound is described as a primary, secondary or tertiary phosphate. Primary and secondary phosphates contain hydrogen and are acid salts. Secondary and tertiary phosphates, with the exception of those of sodium, potassium and ammonium are insoluble in water. Tertiary sodium phosphate is valuabl...
