How do you change oxygen and hydrogen to to liquids?
By cooling them
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.
Is breaking water up into oxygen and a hydrogen gas a physical or chemical change?
Breaking water into the component parts of hydrogen and oxygen is a CHEMICAL change.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
Are hydrogen and oxygen a change of state?
If water is being split into hydrogen and oxygen then a change of state (phase change) will occur if the water is in liquid form and the hydrogen and oxygen are evolved as gases. If water vapor is being split, then obviously no change of state occurs. Conversely, solid water in the form of ice could be split into hydrogen and oxygen gas, also undergoing a phase change.
What is a sentence using hydrogen oxygen chemical change compound water?
There are many sentences that could include these terms. One such sentence is the following: The process by which hydrogen and oxygen convert to water is a chemical change. Also: water is formed in a chemical change involving hydrogen and oxygen.
Is the element hydrogen and oxygen combine to form hydrogen peroxide a chemical change?
Yes it is.
Can humans breathe oxygen and hydrogen combine?
Humans cannot breathe a combination of pure oxygen and hydrogen. Oxygen is necessary for respiration, but hydrogen is highly flammable and not suitable for breathing. Mixing the two gases is dangerous and can create a potential explosion hazard.
Why do humans need hydrogen to survive?
Hydrogen is the most abundant element in the universe. We humans are mostly full of water, water is made of 2 parts hydrogen and 1 part oxygen meaning that if we don't have Hydrogen we also have no water.
Is the air on mercuery breathable?
