In normal conditions oxygen is a colourless, odourless and insipid gas; it condensates in a light blue liquid. Oxygen is part of a small group of gasses literally paramagnetic, and it’s the most paramagnetic of all. Liquid oxygen is also slightly paramagnetic.
What are 4 uses of oxygen?
Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.
What are three chemical properties oxygen?
Oxygen is a colorless, odorless, tasteless gas. It changes from a gas to a liquid at a temperature of -182.96°C (-297.33°F). The liquid formed has a slightly bluish color to it. Liquid oxygen can then be solidified or frozen at a temperature of -218.4°C (-361.2°F).
What is the chemical form of oxygen?
CHEBI:15379 – dioxygen. Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.
What are 5 chemical properties examples?
Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
What are the properties and uses of oxygen?
Oxygen is a highly reactive element, highly paramagnetic, and is easily capable of combining with other elements. One of oxygen’s most important chemical properties is that it supports combustion. Oxygen also combines with elements at room temperature, for example, the formation of rust.
What are 5 uses of nitrogen?
The chemical industry uses this gas in the production of fertilizers, nylon, nitric acid, dyes, medicines, and explosives. Here are the five applications of nitrogen in everyday life.
What are 2 chemical properties of oxygen?
In normal conditions oxygen is a colourless, odourless and insipid gas; it condensates in a light blue liquid. Oxygen is part of a small group of gasses literally paramagnetic, and it’s the most paramagnetic of all. Liquid oxygen is also slightly paramagnetic.
Does oxygen have chemical properties?
Chemical Properties of Oxygen At standard temperature and pressure (STP), two atoms of the element bind to form dioxygen, a colorless, odorless, tasteless diatomic gas with the formula O2. Oxygen is a strong oxidizing agent and has the second-highest electronegativity of all reactive elements, second only to fluorine.
What are 3 chemical properties of nitrogen?
Chemical properties of nitrogen – Health effects of nitrogen – Environmental effects of nitrogen Atomic number 7 Electronegativity according to Pauling 3.0 Density 1.25*10 – 3 g.cm – 3 at 20°C Melting point -210 °C Boiling point -195.8 °C.
Why is oxygen very reactive?
Oxygen Exhibits High Reactivity Due to its electronegativity, oxygen forms stable chemical bonds with almost all elements to give the corresponding oxides. The combination of water and oxygen is even more corrosive. Virtually all elements burn in an atmosphere of oxygen or an oxygen-rich environment.
Who invented oxygen?
Joseph Priestley (1733-1804) — Unitarian minister, teacher, author, and natural philosopher — was the Earl of Shelburne’s librarian and tutor to his sons. In this room, then a working laboratory, Priestley pursued his investigations of gases. On 1 August 1774 he discovered oxygen.
What is pure oxygen used for?
Proponents of this oxygen “therapy” say it boosts energy levels, increases your endurance during exercise, helps you bounce back more quickly from physical exertion, provides relief from stress and pollution, increases your concentration, helps you relax, and eases headaches and hangovers.
What are the 7 chemical properties?
Here are some examples of chemical properties: Reactivity with other chemicals. Toxicity. Coordination number. Flammability. Enthalpy of formation. Heat of combustion. Oxidation states. Chemical stability.
Is color a chemical property?
Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties. Properties that describe how a substance changes identity to produce a new substance are chemical properties.
How do you determine a chemical property?
Chemical properties can only be established by changing a substance’s chemical identity, and are different from physical properties, which can be observed by viewing or touching a sample. The internal qualities of a substance must be altered to determine its chemical properties.
What is the color of oxygen?
We’re observers, however, so the real trick is how oxygen gets us to pretty colors. (Actually, though it’s a colorless gas, oxygen liquefies into an attractive blue fluid.) In its gaseous form, oxygen usually doesn’t glow.
What is the importance of oxygen?
Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.
What are 4 uses of nitrogen?
Let’s take a look at 5 every day uses for nitrogen gas. Preservation of Food. Nitrogen gas is used to help with food preservation by preventing oxidative damage leading to food spoiling. Pharmaceuticals Industry. Electronics Manufacturing. Stainless Steel Manufacturing.
How do humans use nitrogen?
Nitrogen is a component of proteins, nucleic acids, and other organic compounds. It is used to make amino acids in our body which in turn make proteins. It is also needed to make nucleic acids, which form DNA and RNA. Human or other species on earth require nitrogen in a ‘fixed’ reactive form.
What are uses of liquid nitrogen?
Liquid nitrogen, which has a boiling point of -196C, is used for a variety of things, such as a coolant for computers, in medicine to remove unwanted skin, warts and pre-cancerous cells, and in cryogenics, where scientists study the effect of very cold temperatures on materials.
Which is chemical property?
A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.
Is oxygen a physical or chemical property?
oxygen (O), nonmetallic chemical element of Group 16 (VIa, or the oxygen group) of the periodic table.
What are the chemical properties of water?
Hydrolysis reaction Properties Chemical formula H 2 O Molar mass 18.01528(33) g/mol Odour None Density Solid: 0.9167 g/ml at 0 °C Liquid: 0.961893 g/mL at 95 °C 0.9970474 g/mL at 25 °C 0.9998396 g/mL at 0 °C.
