What are 4 chemical 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).
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 the chemical properties?
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 are 5 chemical properties?
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 is the chemical symbol of oxygen?
O
What are 3 chemical properties of nitrogen?

What is the chemical symbol of nitrogen?
Nitrogen is an element with atomic symbol N, atomic number 7, and atomic weight 14.01. Nitrogen appears as a colorless odorless gas.
What are the physical and chemical 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 H2. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water.
What are the properties of oxygen and hydrogen?
Oxygen and hydrogen share some common characteristic. It is similar in that they are gaseous, odorless but colorless elements. It combines to form water which is vital for all living things. all living things depend to oxygen and hydrogen directly and indirectly.
What are the 10 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.
What is a chemical property simple definition?
A chemical property is any of a material’s properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance’s chemical identity. They can also be useful to identify an unknown substance or to separate or purify it from other substances.
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.
What are three chemical properties soil?
Chemical Analysis. Soil chemical properties, including heavy metal concentrations, pH, total carbon, total nitrogen, CEC, exchangeable calcium (Ca), magnesium (Mg) and potassium (K), exchangeable Al and hydrogen (H) and available phosphorous (P), were determined following standard laboratory methods.
How do you identify a chemical property?
A chemical property describes the ability of a substance to undergo a specific chemical change. To identify a chemical property, we look for a chemical change. A chemical change always produces one or more types of matter that differ from the matter present before the change.
Is ductility a chemical property?
The term that is ductility is a property which is physical of matter as it can be measured or observed without the substance undergoing a change which is chemical.
What are the two important properties of oxygen?
The Physical Properties of Oxygen are as follows: Color : Colorless. Phase : Gas. Odor : Oxygen is an odorless gas. Taste : A tasteless gas. Conductivity : A poor conductor of heat and electricity. Solubility : Slightly soluble in water, alcohol and some other common liquids. Density : It is denser than air.
What is the application of oxygen?
Some of the major applications of oxygen include the following: It is used in oxy-acetylene torch for cutting and welding metals. It is used to remove carbon impurities from the steel during steel production. A mixture of liquid oxygen and powdered charcoal is used as an explosive.
What is the main 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 oxygen properties?
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.
