Does oxygen have a chemical property?
Chemical properties 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 a physical property 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. Dioxygen is one of the common allotropes of oxygen.
Is oxygen a physical thing?
Priority is often given for Priestley because his work was published first. Priestley, however, called oxygen "dephlogisticated air", and did not recognize it as a chemical element….

Is oxygen a chemical?
Oxygen is a chemical element with an atomic number of 8 (it has eight protons in its nucleus). Oxygen forms a chemical compound (O2) of two atoms which is a colorless gas at normal temperatures and pressures.
Is reaction with oxygen a physical property?
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 (Figure 2).
What is not the physical property of oxygen?
Color, phase, odor and boiling point are the physical properties. Reactivity with oxygen depends on the chemical nature of object, thus, it is not a physical property.
Which is a physical property of oxygen quizlet?
A physical property of oxygen is that it is a gas at room temperature. A chemical property of oxygen is that it reacts with iron to form rust.
What is oxygen classified?
Oxygen is a chemical element with symbol O and atomic number 8. Classified as a nonmetal, Oxygen is a gas at room temperature.
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.
What is an example of a chemical property?
The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
What are some chemical properties of oxygen?
Key Properties

Which describes a chemical property of oxygen?
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.
Is oxygen an element or a compound or a mixture?
Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus. Oxygen is a gas at room temperature and has no colour, smell or taste. Oxygen is found naturally as a molecule.
Is oxygen a heterogeneous mixture?
Saltwater is a homogeneous mixture, or a solution. Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture. Water is a substance; more specifically, because water is composed of hydrogen and oxygen, it is a compound. Oxygen, a substance, is an element.
Which is not a chemical property?
Density is not a chemical property. It is a physical property. Electromotive force, Flammability and pH are chemical properties.
Which is a physical property?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points.
What are the 3 physical properties?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
What are examples of physical properties?
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
Which of these is a physical property?
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
