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.
What else can I help you with?
Is separating water into oxygen and hydrogen an example of a change?
Yes, separating water into oxygen and hydrogen is an example of a chemical change. It involves breaking the bonds between the hydrogen and oxygen atoms in water molecules, resulting in the formation of new substances with different properties (oxygen and hydrogen gas).
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 mixing hydrogen and oxygen together a chemical change or a physical change?
Just the mixing of hydrogen and oxygen isn't a change at all. But if they react under specific conditions, you have a chemical change. The reaction might look like this ... 2H2(g) + O2(g) --> 2H2O
What evidence of chemical change is visible when electricity is run through water?
Water can be chemically changed, for instance, when an electric current is run through a sample, separating it into oxygen and hydrogen gas. Chemical change requires a chemical reaction, a process whereby the chemical properties of a substance are altered by a rearrangement of the atoms in the substance.Added:What is visible: it is gas bubles of hydrogen and oxygen coming out from the electrodes: O2 at the positive anode, H2 at the negative cathode.
Is burning of hydrogen in air chemical change?
Yes, burning of hydrogen in air is a chemical change because it involves a reaction between hydrogen and oxygen molecules to form water, releasing heat and light energy in the process.
Is separating water into oxygen and hydrogen an example of a change?
Yes, separating water into oxygen and hydrogen is an example of a chemical change. It involves breaking the bonds between the hydrogen and oxygen atoms in water molecules, resulting in the formation of new substances with different properties (oxygen and hydrogen gas).
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
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 Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical 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 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 mixing hydrogen and oxygen together a chemical change or a physical change?
Just the mixing of hydrogen and oxygen isn't a change at all. But if they react under specific conditions, you have a chemical change. The reaction might look like this ... 2H2(g) + O2(g) --> 2H2O
Is decomposing water physical or chemical change?
Chemical change; bonds are broken when water decomposes into hydrogen and oxygen.
What are the two criteria for whether a change is chemical or physical?
Oxygen and hydrogen
Is a sugar a chemical change?
Sugar is a chemical compound or rather a group of compounds containing carbon oxygen and hydrogen, not a chemical change.
Is hydrogen peroxide a chemical or physical change?
Catalase breaks down hydrogen peroxide into water and oxygen. Catalase is found in blood and bacteria in the wound. The bubbles you see are from the oxygen that is being released.
