Oxygen is one of the gases that humans use daily. It is necessary to support life itself. Other common gases used on a daily basis include carbon dioxide and methane.Continue Reading
All animals require oxygen. Most remove oxygen from the air through the lungs, although fish use their gills to remove dissolved oxygen from water. In animals, cells that do not receive oxygen die.
Oxygen is also required for combustion. Homes that burn fuel for heat require oxygen to support the flame. Every time the gasoline engine of a car starts, it uses oxygen that combines with the fuel to produce power.
Carbon dioxide is one of the waste gases that results from respiration in animals. It is required for plants to produce glucose for energy. Since carbon dioxide does not support combustion, fire extinguishers use the compressed gas to stop fires. Pressurized carbon dioxide, found in cans of soda, causes the bubbles in soft drinks.
Methane is a simple hydrocarbon consisting of one carbon atom and four hydrogen atoms. Methane is the primary ingredient of natural gas that many homes use for heat. Methane forms from the breakdown of plant and animal waste. Such breakdowns occur in swamps and manure heaps. Methane is a greenhouse gas that, along with carbon dioxide, contributes to climate change.Learn more about Chemistry
Oxygen has eight electrons. Therefore, its atomic number is 8. It has two electrons in its first shell and six electrons in its second shell.Full Answer >
Oxygen has 8 neutrons, 8 electrons and 8 protons, making it a neutral element. Neutral elements have the same number of neutrons and protons. Oxygen is the eighth element in the periodic table of elements, with an atomic number of 8.Full Answer >
Oxygen is a non-flammable gas that is colorless and odorless. It has a melting point of 54.36 Kelvin and a boiling point of 90.19 Kelvin. Oxygen speeds the rate of combustion by acting as an oxidizing agent.Full Answer >
Oxygen is a highly soluble element that is critical to biological functions, notably respiration. It comprises about 16 to 21 percent of Earth's atmosphere, allowing it to be inhaled and converted to carbon dioxide to power the cells of aerobic organisms. Most animals and plants on Earth require oxygen to survive. Generally, plants convert carbon dioxide to oxygen, and animals convert oxygen to carbon dioxide, during respiration.Full Answer >
