REDUCTION Oxygen makes up only about 20% of the air‚ yet is the essential component for so many reactions. Without it fuels would not burn‚ iron would not rust and we would be unable to obtain energy from our food molecules through respiration. Indeed animal life on the planet did not evolve until a certain concentration of oxygen had built up in the atmosphere over 600 million years ago. The term oxidation has been in use for a long time to describe these and other reactions where oxygen is added

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

The human respiratory system is adapted to allow air to pass in and out of the body and also for efficient gas exchange to occur. The respiratory system includes air passages‚ pulmonary vessels‚ the lungs‚ and breathing muscles. Most of the organs of the respiratory system help to distribute air‚ but only the tiny alveoli and the alveolar ducts are responsible for the gas exchange. Mouth - The mouth is the secondary exterior opening for the respiratory system. Most commonly‚ the majority of respiration

function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. The regulation of breathing is the result of a complex interaction involving a system of sensors‚ a respiratory control center‚ and an effector system to carry out its

Respiratory System The respiratory system is the bodies way to inhale and exhale air and diffuse oxygen. This system consists of several organs such as the trachea‚ lungs‚ larynx‚ pharynx‚ etc. All of these organs work together to help us breathe and are formed to their function. There is two different ways of respiration; external respiration which is the exchange of gases between the alveoli and the blood‚ and internal respiration which is the exchange of gases between the blood and tissue cells

My Journey through Song Natosha Robinson Strayer University Psy-105 Intro to Psychology Clinton D. Gortney 4/29/13 My Journey through Song “This Little Light of Mine” written by Harry Dixon Loess in1920‚ is a popular song that I frequented as a child in the church choir. (Refrence.com Answers‚ 2013) Moving on through school‚ I learned how much singing played a major part of my academic career. Now as an adult‚ I give back through singing. Singing is both therapeutic and calming.

Oxygen in Liquids (DISSOLVED OXYGEN) Dissolved Oxygen – the amount of dissolved oxygen in a body of water as an indication of the degree of the health of water and its ability to support a balanced aquatic ecosystem. Oxygen – is a clear‚ colorless‚ odorless‚ and tasteless gas that dissolves in water. Small but important amounts of it are dissolved in water. OXYGEN: Aquatic Life Depends on it Plants and Animals depend on dissolved oxygen for survival. Lack of dissolved oxygen can cause aquatic
