On the periodic table‚ oxygen is the 8th element. It is located in period 2 and group 16. Oxygen is classified into many things. For example‚ on the periodic table‚ oxygen is classified as a nonmetal gas with an atomic number of 8 and atomic weight of 15.9994. In addition‚ it has 6 valence electrons. The symbol of oxygen is O and oxygen has 8 protons‚ 8 neutrons‚ and 8 electrons. The electron configuration of oxygen is 1s2‚ 2s2‚ 2p4. Oxygen had been produced by several chemists prior to its discovery

Oxygen – Carbon dioxide Cycle The Carbon Dioxide- Oxygen Cycle relates to the relationship between Carbon Dioxide [CO2] breathing plants and Oxygen [O2] breathing life forms. All oxygen-breathing life forms take in Oxygen and exhale CO2. Plants take in the CO2 and use it in their photosynthesis process and in turn give off oxygen. The Carbon Dioxide-Oxygen Cycle is a continuously occurring process whereby animals inhale Oxygen and then exhale carbon dioxide‚ and plants use the CO2 and "exhale"

Water Quality Standards & Criteria Daphne Landy EVS 1001-52 Everest University Water Quality Standard & Criteria How are water quality standards determined? The standard for water quality is determined by the National Recommended Water Quality Criteria. They first have to determine when water is considered polluted (Wright & Boorse‚ 2011). Some pollutants that are identified in water are due to human activity or interactions. Most of these type of pollutants come from chemicals

Albert Fish was born on May 19‚1870 in Washington‚ D.C. and was placed in an orphanage at age five after his father passed away. While at the orphanage‚ he observed and experienced a number of perversions including forced masturbation in front of other children and brutal beatings. At the age of 7‚ Albert was reunited with his mother. Shortly thereafter‚ he fell from a cherry tree resulting in severe head trauma which caused him dizzy spells and terrible headaches.

or Water? PURPOSE The purpose of this lesson is to investigate the heat capacity of water and land and to explain how the properties of water influence coastal climates. EXPERIMENTAL DESIGN In this experiment‚ you will heat the same volume of water and sand or soil in two different containers. They will compare the temperatures of the water and the sand or soil as each beaker is heated and as each beaker cools to answer the question: Which Absorbs and Loses Heat Faster––Land or Water?

The question being looked into is “What is the water quality of the U-High creek‚ based on invertebrates found in the U-High Creek? “Dissolved oxygen is oxygen mixed with water. The range to measure how much dissolved oxygen is in a solution is 1-14 milligrams per liter. This is important because fish and other organisms in the ocean breathe off of dissolved oxygen. Phosphorus is used to measure the relative acidity of solutions such as water. The range for pH is measured in 0-14 scale. 0-6 is unhealthy

Salt Water or Fresh Water‚ Which Would You Prefer? Many people wonder‚ what big differences are between salt water and fresh water? Is it just water with salt versus water without salt? Those are some common questions people have. Most people ask about the differences‚ but they forget about the similarities of salt water and fresh water‚ as well. Did you know that Salt water and fresh water have very different plant and animal life? There are also a few complex fish that can live in both

Introduction Paragraph The question that’s being investigated is what is the water quality of the U-high creek based on the macroinvertebrates found in the creek. Water quality can be measured in various ways including oxygen levels‚ pH‚ nitrogen and phosphorus levels. Dissolved oxygen is when oxygen molecules mix with water molecules. It is important because water gets into oxygen from the surrounding air.The pH scale is used to measure the relative acidity of solutions and phosphorus is a chemical
