Hydrogen, or hydro, is a chemical substance that is always around us. However, not everyone truly understands this chemical. Therefore, the question is raised: What is Hydrogen? Does Hydrogen gas sustain combustion? What are the applications of Hydrogen in life?
To unravel these questions, readers can find information in the article that follows.
What is Hydrogen Gas?
There are many different ways to write Hydrogen, such as: Hiđro, hi-đrô, hít-rô.
This is one of the chemical elements in the periodic table with an atomic number of 1 and an atomic mass of 1 amu. Therefore, Hydrogen contains only one proton and no neutron.
According to research by scientists, Hydrogen usually exists in gaseous form and therefore often combines with other elements to exist. For this reason, Hydrogen often combines with Oxygen to form water molecules.

Hydrogen combines with Oxygen to form water molecules
Hydrogen is produced from the combustion of coal, natural gas, biodegradable substances, etc. Besides, Hydrogen is also produced from clean energy sources such as wind, sunlight, water, etc.
Does Hydrogen Gas Sustain Combustion?
What is Combustion?
Combustion is a high-temperature exothermic redox reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture called smoke.
Combustion produces a flame, and generates heat sufficient to make the reaction self-sustaining.
Does Hydrogen Sustain Combustion?
After understanding what Hydrogen is, readers may wonder if Hydrogen gas sustains combustion. This will be explained by the following information:
- Hydrogen is a chemical element whose atom has only one electron. Therefore, it can quickly combine with other elements to form completely new compounds.
- As we analyzed above, Hydrogen usually exists as a gas in nature, linked by a relatively weak H-H bond.

Hydrogen gas sustains combustion to produce light and heat
- Due to its weak bond, Hydrogen can be rapidly oxidized if it encounters oxygen. Therefore, Hydrogen is very flammable.
- The combustion process of Hydrogen with oxygen to form a new compound – Water (H2O) – releases a huge amount of thermal energy. This is the reason why humans use it as fuel for spacecraft to successfully launch into outer space.
At this point, you can understand that: Hydrogen gas sustains combustion under the condition of oxygen. This combustion occurs for a certain period. When it starts burning, Hydrogen will emit a loud explosion, the flame will be pale blue, and water vapor will be produced.
Applications of Hydrogen in Life
What is hydrogen gas used for? Currently, the applications of hydrogen in life span across many different fields. When learning about Hydrogen gas, you will notice some prominent applications of H2 as follows:
Applications of hydrogen: Used as fuel for engines
As we know, Hydrogen gas burns and produces a very large amount of heat. Compared to other fuels such as gasoline and oil, Hydrogen gas produces a much larger amount of heat.
Therefore, Hydrogen gas is used as the main fuel for many engines such as car engines, rockets, airplanes, etc. This is a valuable source of fuel that humans are looking for to replace gasoline and oil.

Besides, hydrogen gas is also used as a raw material to produce acids and organic compounds used in agriculture and forestry. When these compounds are created, plants and organisms will easily absorb nutrients.
In addition, Hydrogen gas sustains combustion; it is a very light gas and is therefore often used as a material to inflate hot air balloons and exploration balloons. Closer to everyday life, it is used to inflate balloons at important events and festivals.
Applications of hydrogen gas: Used in human healthcare

The applications of hydrogen in life are increasingly evident. Hydrogen is a product created by electrolysis through ionization. Therefore, Hydrogen has the ability to resist the strong oxidation process that occurs in the human body.
This is achieved through the mechanism of neutralizing a series of free radicals inside the body when suffering from chronic diseases, especially the skin aging process.
Improves and reduces the skin aging process in humans
Hydrogen can dissolve in water and oil. Therefore, it can penetrate deep into the cells of the body very easily. Thus, cells weakened by pathogenic agents will have their oxidation neutralized thoroughly. From there, it will help humans defeat pathogens that can cause cancer.
Besides, active Hydrogen entering the body will break down oxidation reactions. This helps you achieve whiter, firmer, and smoother skin.
Applications of hydrogen in industry: Used as a reducing agent
Hydrogen Sulfide is used as a reducing agent to separate metals from oxides in the laboratory. At the same time, the application of hydrogen in industry is for the preparation of metals in industrial parks, especially factories producing iron, steel, aluminum, etc.
