How does a Hydrogen powered car work?
Hydrogen gas reacts with oxygen gas to form water and gives off energy in the process. This energy, mostly in the form of heat, can be used as an energy source. Hydrogen fuel cells are specialized to react the hydrogen and oxygen in an optimal way so that maximum energy can be harnessed. The source of the energy is the hydrogen gas that is synthesized in a lab, usually by the electrolysis of water (which means running electrical energy through water causing it to separate into oxygen and hydrogen gas). The energy used to create the hydrogen gas can come from many sources including fossil fuels, solar, hydroelectric, etc.
How are the oxygen molecules in a molecule of oxygen held together?
If you are mentioning about sticking two hydrogen atoms with one oxygen atom, then it's water. Other than that, oxygen and hydrogen are not together, unless they are water, hydrogen peroxide, or some other compound with an -OH group. In such compounds the hydrogen and oxygen are held together by covalent bonds, the sharing of electrons.
Describe 3 different way of making hydrogen from other chemicals?
Steam methane reforming: Natural gas is mixed with steam at high temperatures to produce hydrogen and carbon monoxide. Electrolysis: Water is split into hydrogen and oxygen using electricity. Gasification: Organic materials such as biomass or coal are reacted with oxygen or steam at high temperatures to produce hydrogen gas.
How do you separate hydrogen from steam?
Hydrogen can be separated from steam by using a process called water electrolysis, where an electric current is passed through water to split it into hydrogen and oxygen gas. Another method is using a membrane-based separation technology that allows hydrogen to permeate through while leaving behind the steam.
How is hydrogen produced commercially?
"electrifying water to separate the oygen and the hydrogen" (aka electrolysis) is very expensive and is only used to create laboratory grade hydrogen. According to this source: http://www.thenewatlantis.com/publications/the-hydrogen-hoax most commercial hydrogen is created from hydrocarbons, like natural gas and petroleum byproducts. The author of this article claims that creating hydrogen this way creates more CO2 than burning the hydrocarbons for fuel directly.
What is a sentence using the word hydrogen?
Hydrogen and oxygen combined with a catalyst create water.
Does glycolysis happen with or without oxygen?
Many types of bacteria can live in Anaerobic conditions, I.e they don't need oxygen to live, as they create energy using anaerobic respiration.
Does platinum change water back to hydrogen and oxygen?
Does platinum change water back to hydrogen and oxygen using a current
Is using electricity to separate water into hydrogen and oxygen a chemical change?
Yes, using electricity to separate water into hydrogen and oxygen is a chemical change because it involves breaking the bonds between the hydrogen and oxygen atoms in water molecules to form separate hydrogen and oxygen molecules. This process is known as electrolysis.
Do hydrogen and oxygen react with water?
Hydrogen and oxygen do react with water. When hydrogen reacts with oxygen in the presence of water, it forms water again. This reaction can be seen in the process of electrolysis, where water is split into its components, hydrogen and oxygen, using electric current.
What fuels fuel cell cars?
Fuel cells in vehicles create electricity to power an electric motor, generally using oxygen from the air and compressed hydrogen.
What are fuel-cell cars powered by?
Fuel cells in vehicles create electricity to power an electric motor, generally using oxygen from the air and compressed hydrogen.
How do you create hydrogen?
you can not "create" hydrogen. you can release it from chemical bonds such as from water. to extract hydrogen from water you need to pass an electrical current through the water and capture the gas which comes out, however this is hydrogen and oxygen.
What is the combination of hydrogen and oxygen to create energy that can be used in cars?
The combination of hydrogen and oxygen to create energy for cars typically involves a process called electrolysis, where water (H₂O) is split into hydrogen (H₂) and oxygen (O₂) using electricity. The hydrogen can then be stored and used in fuel cells, where it reacts with oxygen to produce electricity, water, and heat. This electricity powers electric motors in vehicles, providing a clean energy alternative to traditional fossil fuels. The only byproduct of this reaction is water, making it an environmentally friendly option for transportation.
Can you remove all the hydrogen from water using an endothermic reaction?
Yes. It is possinle to split water into hydrogen and oxygen using electrolysis.
How are hydrogen cars powered?
Generally, a Hydrogen powered car runs by using hydrogen and oxygen to create electricity in a fuel cell, which is then used to power an electric traction motor that runs the car. Direct ignition-engines are more difficult and dangerous to 'run'.
How can metal be rusted without using hydrogen peroxide?
Metal can be rusted through a process called oxidation, which occurs when the metal comes into contact with oxygen and moisture in the air. This causes the metal to corrode and form rust, even without the use of hydrogen peroxide.
