Why is separating water into oxygen and hydrogen chemical change?
Separating water into oxygen and hydrogen is a chemical change because it involves breaking the chemical bonds within the water molecule and forming new bonds to create the two separate elements. This process requires a reaction to occur, resulting in a chemical transformation.
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 Compound is made up of hydrogen or oxygen?
Compound can be made up of both hydrogen and oxygen. For example, water (H2O) is a compound made up of hydrogen and oxygen atoms.
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.
Why is it difficult to get pure hydrogen and oxygen?
It is difficult to obtain pure hydrogen and oxygen because they are typically found in combination with other elements in compounds such as water (H2O). Separating hydrogen and oxygen from these compounds usually requires energy-intensive processes like electrolysis or chemical reactions, which can be complex and expensive to carry out at a large scale.
Separating water into oxygen and hydrogen is an example of?

Why is separating water into oxygen and hydrogen chemical change?

Is hydrogen and oxygen combining to form water and example of a physical change?
No, it is not.
Separating water into hydrogen gas and oxygen gas requires electricity this reaction is an example of an?
electrolysis reaction, where an electric current is used to drive a non-spontaneous chemical change. In this case, water is being split into its constituent elements of hydrogen and oxygen through the application of electrical energy.
One example of chemical change is what?
Burning hydrogen (hydrogen + oxygen -> water: 2H2 + O2 => 2H2O)
Can oxygen and hydrogen be mixed after separating them from air?
No one obtains hydrogen by separating it from air. There's not enough hydrogen present in air for that to be a viable source. However, it's possible to mix oxygen and hydrogen, yes. It forms a flammable (and explosive, if you get the proportions just right) mixture of gases.
Can hydrogen be collected out of water by separating it from oxygen using fish gills?
No, fish gills cannot be used to separate hydrogen from oxygen in water. Fish gills are specialized organs for extracting dissolved oxygen from water to support respiration in aquatic animals. The process of separating hydrogen from oxygen in water to obtain hydrogen gas requires specific methods like electrolysis or steam reforming.
Example of physical change and a chemical change?
when water changes to water vapour by heating is an example of physical change. when water is divided into oxygen and hydrogen by passing electricity is an example of chemical change.
What is the difference of water molecules separating and breaking apart?
Water molecules separating means they are spreading, or in other words, the water is evaporating. When they are breaking apart, the hydrogen and oxygen are separating.
Does platinum change water back to hydrogen and oxygen?
Does platinum change water back to hydrogen and oxygen using a current
What is one example of a chemical change?
Burning hydrogen (hydrogen + oxygen -> water: 2H2 + O2 => 2H2O)
How do you change oxygen and hydrogen to to liquids?
By cooling them
