Physical properties of oxygen gas:
Oxygen (O2) is a colorless, odorless, and tasteless gas at room temperature.
It is slightly soluble in water and more soluble in non-polar solvents.
Oxygen is a non-metallic element and has a relatively high electronegativity.
It is slightly denser than air and can accumulate in low-lying areas, which can pose a hazard to human health.
Chemical properties of oxygen gas:
Oxygen is a highly reactive gas that readily undergoes a variety of chemical reactions.
It is a powerful oxidizing agent, which means it is capable of accepting electrons from other molecules.
Oxygen gas can react with many metals, such as iron, to form metal oxides.
It can also react with many organic compounds to form oxygenated organic compounds, which are commonly used in the production of fuels and solvents.
Oxygen gas can also react with non-metals, such as carbon, to form oxides.
Oxygen gas molar mass
The molar mass of oxygen gas (O2) is approximately 32.00 g/mol.

In this structure, each oxygen atom has six valence electrons. The two atoms share two electrons in a double bond to form a stable molecule. The shared electrons are represented by a pair of lines between the oxygen atoms, while the remaining valence electrons are represented by dots around the atoms.
Uses of oxygen gas:
Oxygen gas is used in the production of steel and other metals, where it is used to promote combustion and to remove impurities.
It is also used in medical applications, such as in oxygen therapy for people with respiratory problems and in the treatment of carbon monoxide poisoning.
Oxygen gas is used in the production of some chemicals and in some industrial processes, such as in the production of ethylene oxide and in wastewater treatment.
It is also used in the aerospace industry, where it is used as an oxidizer in rocket engines and to support life in spacecraft.
Reactions of oxygen gas with other compounds:
Oxygen gas can react with metals, such as iron, to form metal oxides.
It can react with non-metals, such as carbon, to form carbon dioxide or carbon monoxide, depending on the conditions of the reaction.
Oxygen gas can also react with organic compounds to form oxygenated organic compounds, such as alcohols and ketones.
In combustion reactions, oxygen gas reacts with a fuel, such as hydrocarbons, to produce carbon dioxide and water.
Sulfur dioxide gas reacts with oxygen gas to make sulfur trioxide gas.
The chemical equation for the reaction between sulfur dioxide gas (SO2) and oxygen gas (O2) to form sulfur trioxide gas (SO3) is:
2SO2(g) + O2(g) → 2SO3(g)
In this reaction, two molecules of sulfur dioxide and one molecule of oxygen react to form two molecules of sulfur trioxide. This reaction generates heat, hence it is considered exothermic. The reaction is commonly used in the production of sulfuric acid, which is an important industrial chemical used in many applications, including the production of fertilizers, detergents, and batteries.
How to produce Oxygen gas?
Oxygen gas can be produced in several ways, including:
Fractional distillation of air:
Oxygen gas can be obtained by separating it from the air through fractional distillation. Air is cooled to very low temperatures, which causes the different gases in the air to liquefy. Oxygen can then be separated from the other gases by taking advantage of its lower boiling point.
Electrolysis of water:
Oxygen gas can also be produced by electrolysis of water, which involves passing an electric current through water to break it down into its constituent elements, hydrogen and oxygen. The oxygen gas is then collected and purified.
Decomposition of compounds:
Some compounds, such as hydrogen peroxide, can be decomposed to produce oxygen gas. For example, hydrogen peroxide can be decomposed into water and oxygen by heating it or using a catalyst.
Photosynthesis:
Oxygen gas is produced as a byproduct of photosynthesis, which occurs in plants and some bacteria. During photosynthesis, plants absorb carbon dioxide and water, and with the help of sunlight, produce oxygen and glucose.
Boost oxygen
Boost Oxygen is a brand of portable, lightweight, and easy-to-use oxygen canisters that are designed to provide supplemental oxygen to individuals in need. The product is marketed as a way to increase energy, improve cognitive performance, and alleviate the symptoms of altitude sickness.
Boost Oxygen canisters contain 95% pure oxygen, which is significantly higher than the 21% oxygen concentration in the air we breathe. The canisters are available in different sizes, ranging from pocket-sized to larger canisters that are meant for home use.
Boost Oxygen is commonly used by athletes, hikers, and individuals who live in high-altitude locations, as well as those who suffer from respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD). However, it’s important to note that Boost Oxygen is not a substitute for medical treatment, and individuals with severe respiratory conditions should always consult with a healthcare provider before using the product.
