What are 5 oxygen properties?
The key properties of oxygen are listed below:
- It is a colorless, odorless and tasteless gas.
- It readily dissolves in cold water.
- It is highly reactive and form oxides with almost all elements except noble gases.
- Liquid oxygen is strongly paramagnetic.
- It exists in three allotropic forms- monoatomic, diatomic and triatomic.
What type of properties oxygen is?
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 is an example of a chemical property of oxygen?
Chemical properties of oxygen
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. Decaying is an example of oxygen reacting with compounds. Carbon dioxide and water are the main products of decay.
What are physical properties of oxygen?
Physical Properties of Oxygen
The gas is colourless, odourless and insipid in a normal state. Liquid oxygen is slightly paramagnetic. It is reactive and forms oxides with every element except helium, neon, krypton, and argon. It is moderately soluble in water.
What are 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.
Is oxygen is a matter?
oxygen (O), nonmetallic chemical element of Group 16 (VIa, or the oxygen group) of the periodic table.

Is oxygen heavier than air?
Air is heavier than oxygen.
What are 5 chemical properties examples?
Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize ([link]).
What are the 4 chemical properties?
Flammability. Heat of combustion. Enthalpy of formation. Chemical stability under specific conditions.
What Colour is oxygen?
colorless
The gas is colorless, odorless, and tasteless. The liquid and solid forms are a pale blue color and are strongly paramagnetic.
What is pure oxygen?
Pure oxygen is a term used to describe a gaseous mixture containing more than 90 percent oxygen. Regular air we breathe contains roughly 21 percent oxygen.
Why is air called matter?
Answer and Explanation: Air is classified as matter because it has mass and takes up space, which is the definition of matter.
Is fire a matter?
Since matter can be defined as “anything which occupies space and has mass or weight”, we can say that fire is a ‘matter’ because it occupies space and since it is a mixture of gases, it must have some mass. The light and the heat produced by the flame is energy.
Does pure oxygen burn?
The technical reality is that the oxygen doesn’t burn,” said Mark Bruley, vice president for accident and forensic investigation at ECRI Institute. “It’s a subtlety of the physics of fire. Oxygen makes other things ignite at a lower temperature, and burn hotter and faster. But oxygen itself does not catch fire.”
Is hydrogen hot or cold?
Hydrogen has the second lowest boiling point and melting points of all substances, second only to helium. Hydrogen is a liquid below its boiling point of 20 K (–423 ºF; –253 ºC) and a solid below its melting point of 14 K (–434 ºF; –259 ºC) and atmospheric pressure. Obviously, these temperatures are extremely low.
What are the 4 chemical properties of matter?
Reactivity, flammability, and the ability to rust are among them. The tendency of matter to react chemically with other substances is known as reactivity. Flammability, toxicity, acidity, the reactivity of various types, and heat of combustion are examples of chemical properties.
What are 4 chemical properties?
Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
What are the 3 chemical properties of matter?
Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust.
What are five chemical properties?
Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability. A chemical change or reaction is a process in which one substance changes to another substance.
What color Is A Mirror?
A mirror might look silver because it’s usually depicted that way in books or movies. However, it’s actually the color of whatever is reflected onto it. A perfect mirror has specular reflection, meaning it reflects all light in a single direction equal to what it receives.
Why does blood turn red?
Hemoglobin bound to oxygen absorbs blue-green light, which means that it reflects red-orange light into our eyes, appearing red. That’s why blood turns bright cherry red when oxygen binds to its iron. Without oxygen connected, blood is a darker red color.
Can you breathe 100% oxygen?
The concentration of oxygen in normal air is only 21%. The high concentration of oxygen can help to provide enough oxygen for all of the organs in the body. Unfortunately, breathing 100% oxygen for long periods of time can cause changes in the lungs, which are potentially harmful.
Can humans breathe pure oxygen?
To breathe pure oxygen at that level for any longer can have toxic results, including “shock lung,” or adult respiratory distress syndrome. In infants, too much pure oxygen for too long a time can also lead to retinal problems as the blood vessels in their eyes won’t develop properly.
Is water matter Yes or no?
On earth, solid, liquid, and gas are the most common states of matter. Not only is water the most common substance on earth, but it is also the only substance that commonly appears as a solid, a liquid, and a gas within the normal range of earth’s temperatures.
Is sound is a matter?
Sound is a little different in that it is the propagation of a pressure wave through a medium of particles. Since it is a wave, it is not considered a form of matter.
