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 5 chemical properties examples?
Examples of chemical properties include
flammability, toxicity, acidity, reactivity (many types)
, and heat of combustion.
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.
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 oxygen?
Atomic number 8 | Electronegativity according to Pauling 3.5 | Density 1.429 kg/m 3 at 20°C | Melting point -219 °C | Boiling point -183 °C |

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 physical properties of 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 are the 7 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 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 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 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 formula of oxygen?
Chemical formula O 2 | Molar mass 32.00 g/mol | Boiling Point -183 o C | Melting Point −219°C |
