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 are the 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 O
2
. - Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element.
What are the 3 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 physical properties of an element?
Physical properties include
color, density, hardness, and melting and boiling points
.
What are physical 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.
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 is the formula of oxygen?
| Chemical formula O 2 | Molar mass 32.00 g/mol | Boiling Point -183 o C | Melting Point −219°C |
|---|
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 some examples of oxygen?
Oxygen occurs in all kinds of minerals. Some common examples include the
oxides, carbonates, nitrates, sulfates, and phosphates
. Oxides are chemical compounds that contain oxygen and one other element. Calcium oxide, or lime or quicklime (CaO), is an example.
Who named oxygen?
Among them was the colorless and highly reactive gas he called “dephlogisticated air,” to which the great
French chemist Antoine Lavoisier
would soon give the name “oxygen.”
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 the 15 properties of matter?
The properties of matter include any traits that can be measured, such as an
object’s density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more
.
What are the examples of physical and chemical properties?
The
general properties of matter such as color, density, hardness
, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.
What are 5 physical properties of hydrogen?
At standard temperature and pressure, hydrogen is a
nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas
with the molecular formula H
2
. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water.
