Hydrogen electric cars are powered by a fuel cell which changes hydrogen into water and generates electricity. Its zero carbon emissions helps lower air pollution but there are drawbacks to these vehicles. First, hydrogen will evaporate over time and is very combustible. Also, there is no hydrogen distribution system in America at the present. Automobile companies are researching ways to overcome these drawbacks.
What else can I help you with?
When drain cleaner is added to water bubbles of hydrogen are produced Is what happens to form the bubbles when the cleaner is added a chemical or physical reaction?
If a gas is produced and it isn't a state change (such as steam bubbles forming), the reaction is a chemical change because the molecular makeup of either the water or the drain cleaner has changed and the hydrogen has been liberated.
How can hydrogen be added to water?
Hydrogen can be added to water through a process called electrolysis, where an electric current is passed through water to separate it into hydrogen and oxygen gases.
How is hydrogen manufactured from water?
Hydrogen can be produced from water through a process called electrolysis, where an electric current is passed through water to split it into hydrogen and oxygen. This process requires electricity, and the hydrogen produced can be used as a clean energy source.
Can you get hydrogen back if you burn it?
Yes. When you burn hydrogen the product is water. If you pass an electric current through that water you can split it back into hydrogen and oxygen.
What is used to separate hydrogen and oxygen?
Electrolysis, the passing of electric current through water will separate the water into oxygen and hydrogen molecules.
What do you pass through water to get hydrogen gas?
Electric Current
What happen when electric current is passed through water'?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
How do you strip hydrogen from water?
To strip hydrogen from water, a process called electrolysis is used. In electrolysis, an electric current is passed through water to split it into hydrogen and oxygen gases. The hydrogen gas is collected at the cathode while the oxygen gas is collected at the anode.
What are the key differences between hydrogen fuel cell vehicles and electric cars in terms of their environmental impact and efficiency?
Hydrogen fuel cell vehicles produce water as their only emission, making them cleaner than electric cars that rely on electricity generated from fossil fuels. However, the production of hydrogen can be energy-intensive. Electric cars are more efficient in terms of energy conversion and have a lower overall environmental impact if the electricity comes from renewable sources.
How can you make water from hydrogen hydrogen from water?
Yes. You cannot get water from hydrogen alone. You need oxygen. Since oxygen is a part of the atmosphere, simply burning hydrogen in air will give you water vapor. Passing an electric current through water will split it back into hydrogen and oxygen.
How do you product hydrogen?
pass an electric current through water - H20, and the current will divide the water molecules into hydrogen gas and oxygen gas
What happens when electric current passes through the acidulated water?
Water is dissociated in hydrogen and oxygen.
