How does a hydrocracker work?
A hydrocracker is a high-pressure, high-temperature catalytic reactor that uses hydrogen in the presence of a catalyst to break down heavy hydrocarbon molecules into lighter and more valuable products like gasoline and diesel. The process involves breaking carbon-carbon bonds and saturating carbon-carbon double bonds with hydrogen, resulting in improved fuel quality and increased yield of valuable products.
Why is hydrogen combustible?
Fundamentally, because the Gibbs free energy of elemental hydrogen and oxygen is substantially greater than the Gibbs free energy of the water formed by their chemical reaction, and the activation energy for the reaction is not excessively high.
Density of Hydrogen?
Gaseous hydrogen has a density of 0.08988 g/cm. Liquid and solid hydrogen have a density of about 0.07 g/ccAt standard temperature and pressure (stp), hydrogen as a gas has density 0.08988 grams per litre. Hydrogen atoms have atomic mass of 1, and diatomic hydrogen molecules have molecular mass of 2. From this we can tell that hydrogen is the lightest (least dense) element in the periodic table.
What are The combustible products of most coal gasification techniques?
The combustible products of coal gasification techniques typically include syngas, which is a mixture of carbon monoxide, hydrogen, and other hydrocarbons. These products can be burned as fuel for energy production or further processed into chemicals and other valuable products.
Why does helium not burn like hydrogen?
Helium does not burn like hydrogen because it is chemically inert, meaning it does not easily react with other elements to undergo combustion. Hydrogen, on the other hand, is highly flammable and can readily undergo combustion in the presence of oxygen, making it a valuable fuel source.
What moons are most likely to be visited by humans due to valuable resources?
At this point the only valuable resources would be those useful in refueling rockets for a return voyage, usually oxygen, nitrogen, helium, hydrogen etc.

What is a source of Electrons and hydrogen?
A common source of electrons and hydrogen is water (H₂O). In processes like electrolysis, water can be split into hydrogen gas (H₂) and oxygen gas (O₂) by applying an electrical current. The separation of water molecules provides both electrons, which can be harnessed for electrical energy, and hydrogen, which is a valuable fuel and chemical feedstock. Other sources include organic materials and fossil fuels, which also release electrons and hydrogen during combustion or chemical reactions.
What was the largest pressure ever developed in a laboratory used trying to solidify hydrogen in 1978?
In 1978, researchers at the Lawrence Livermore National Laboratory achieved a record pressure of approximately 250 gigapascals (GPa) while attempting to solidify hydrogen. This immense pressure was part of their efforts to understand the behavior of hydrogen under extreme conditions. Despite these efforts, solid hydrogen was not successfully produced at that time. The experiments contributed valuable insights into the properties of hydrogen and high-pressure physics.
Ask uswhen ethane is cracked in the presence of hydrogen?
When ethane is cracked in the presence of hydrogen, a process known as hydrogen-assisted cracking occurs. This process typically involves breaking down ethane into smaller hydrocarbons or even into its elemental components, while hydrogen can help stabilize the reaction and reduce the formation of unwanted byproducts. The presence of hydrogen can also lead to the production of valuable chemicals like ethylene. Overall, this method enhances efficiency and selectivity in the cracking process.
Can hydrogen be trapped in the air bubbles of ice glacier?
Yes, hydrogen can be trapped in the air bubbles of ice glaciers. During the formation of ice, gases, including hydrogen, can become encapsulated in air bubbles as the snow compacts and freezes. These bubbles can preserve ancient atmospheres and provide valuable information about past climate conditions. However, the concentration of hydrogen is typically low compared to other gases like carbon dioxide and methane.
What are examples of similes for something valuable?
As valuable as children, as valuable as life, as valuable as light, as valuable as water, as valuable as money, as valuable as diamonds
