What else can I help you with?
Are hydrogen and oxygen solids gases or liquids at 20 degrees c?
Hydrogen and Oxygen are gases at 20OC.
Could nitrogen oxygen and hydrogen occur together in mixture of liquids?
Yes, nitrogen, oxygen, and hydrogen can all exist together in a mixture of liquids. These gases can dissolve in liquids to varying degrees depending on factors like temperature and pressure. For example, nitrogen and oxygen are more soluble in water compared to hydrogen.
Does platinum change water back to hydrogen and oxygen?
Does platinum change water back to hydrogen and oxygen using a current
What must be done to oxygen and hydrogen to change them in liquids?
If you mean the individual gases you will need to apply pressure and or reduce the temperature to liquefy the gases. If you mean by forming a compound react them together. The end product is water which is liquid at room temperature and pressure.
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.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.
What is oxygen in a chemical change that produces water?
The reaction between oxygen and hydrogen produce water.
