It is also used to make epoxyethane (ethylene oxide), used as antifreeze and to make polyester, and chloroethene, the precursor to PVC. Oxygen gas is used for oxy-acetylene welding and cutting of metals. A growing use is in the treatment of sewage and of effluent from industry.
Subsequently, one may also ask, what is the purpose of oxygen in the body?
One critical role that oxygen plays in the body is that it is used to oxidize our food, in the process of cellular respiration, thus releasing energy, which is eventually stored in ATP in the electron transport chain in mitochondria, and in glycolysis in the cytoplasm.
Why is oxygen useful?
In nature, oxygen is a gas with no color or smell. Oxygen is a very important element because we need it to live. It is a part of the air people breathe and the water people drink. Many living things (including humans) need oxygen to live and breathe, though it is poisonous to some forms of life.
What does the oxygen can do?
The human body requires oxygen to function. It takes in oxygen and releases waste gas in the form of carbon dioxide. This two-part process is called respiration. The blood carries oxygen to cells throughout the body, where it helps convert nutrients into usable energy.
How is the oxygen used?
Oxygen is used by animals and plants in the respiration (breathing) process. Tanks of oxygen are used in medicine to treat people with breathing problems. They are also used as life support for astronauts and scuba divers. The majority of the oxygen used in industry is used in the manufacturing of steel.
What does oxygen do?
Why do we breathe? (We breathe because oxygen is needed to burn the fuel [sugars and fatty acids] in our cells to produce energy.) What happens in the process of respiration? (Oxygen is brought into the lungs via breathing, where it is transported by red blood cells to the entire body to be used to produce energy.
How oxygen is produced?
Oxygen can be produced from a number of materials, using several different methods. The most common natural method is photo-synthesis, in which plants use sunlight convert carbon dioxide in the air into oxygen. This offsets the respiration process, in which animals convert oxygen in the air back into carbon dioxide.
Where can oxygen be found in the world?
The first two members of the family, oxygen and sulfur, are found in most ores. Oxygen is by far the most abundant element in the Earth’s crust. Nearly half of all the atoms in the earth are oxygen atoms. Oxygen also makes up about one-fifth of the Earth’s atmosphere.
Where the oxygen comes from?
Most of this oxygen comes from tiny ocean plants – called phytoplankton – that live near the water’s surface and drift with the currents. Like all plants, they photosynthesize – that is, they use sunlight and carbon dioxide to make food. A byproduct of photosynthesis is oxygen.
What are some interesting facts about oxygen?
Oxygen (O) has an atomic number of eight. This odorless, colorless gas has eight protons in the nucleus, and is pale blue in its liquid and solid states. Interesting Oxygen Facts: One fifth of the Earth’s atmosphere is made up of oxygen and is the third most abundant element in the universe by mass.
What is the state of oxygen?
Data ZoneClassification:Oxygen is a chalcogen and a nonmetalColor:colorlessAtomic weight:15.9994State:gasMelting point:-218.3 oC, 54.8 K
Where is the oxygen found in nature?
It is the most abundant element found on the Earth and makes up 21% of the atmosphere. As a compound, oxygen is present in water, in plants and animals, and in much of the solid material that makes up the earth. Thousands of compounds contain oxygen, along with carbon, hydrogen, and other elements.
What is made up of oxygen?
Oxygen is the eighth element of the periodic table and can be found in the second row (period). Alone, oxygen is a colorless and odorless molecule that is a gas at room temperature. Oxygen molecules are not the only form of oxygen in the atmosphere; you will also find oxygen as ozone (O3) and carbon dioxide (CO2).
Is Oxygen is a gas?
First a nit-picking point – oxygen (O2) can be a solid, liquid, or gas depending on temperature and pressure. But I’d guess you probably already know that and are asking why oxygen is a gas at normal earth temperatures and pressures.
What is the color of the oxygen?
Properties: Oxygen gas is colorless, odorless, and tasteless. The liquid and solid forms are a pale blue color and are strongly paramagnetic. Oxygen supports combustion, combines with most elements, and is a component of hundreds of thousands of organic compounds.
Is oxygen reactive?
Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element. As such, it readily forms compounds (notably oxides) with almost all other elements.
How the oxygen is obtained?
Fractional distillation of liquid air. You need to be able to explain how nitrogen and oxygen are obtained from the air. You will recall that about 78% of the air is nitrogen and 21% is oxygen. These two gases can be separated by fractional distillation of liquid air.
Is oxygen a solid or a liquid?
Could be the 3 of them, just depends on the temperature and pressure. Of course on earth, with our usual temperature and pressure, we know Oxygen as a gas, but it can exist as a liquid and as a solid.
What is the reaction of oxygen?
Oxygen is very reactive with Alkali metals. Alkali metals are given the name alkali because the oxides of these metals react with water to form a metal hydroxide that is basic or alkaline. Lithium produces an oxide, sodium produces a peroxide, and potassium, cesium, and rubidium produce superoxides.
Is Oxygen is a element?
Element No. 8 on the Periodic Table of the Elements is a colorless gas that makes up 21 percent of Earth’s atmosphere. Because it’s all around, oxygen is easy to dismiss as dull and inert; in fact, it’s the most reactive of the non-metallic elements.
What are 5 things nitrogen is used for?
Nitrogen is important to the chemical industry. It is used to make fertilisers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process.
How does the water get into the air?
Heat from the Sun causes water to evaporate from the surface of lakes and oceans. This turns the liquid water into water vapor in the atmosphere. Plants, too, help water get into the atmosphere through a process called transpiration! Water can also get into the atmosphere from snow and ice.
What does the oxygen family belong to?
Oxygen is the first element in Group 16 (VIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The elements in Group 16 are said to belong to the chalcogen family. Other elements in this group include sulfur, selenium, tellurium, and polonium.
Is o2 an element or a compound?
A molecule is two or more atoms bonded together that may or may not be the same element. A compound is two or more different atoms that are bonded. Thus O2 is only a molecule because it is more that one atom and all atoms of the molecule are the same. “Oxygen gas” is not an element.
