Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
What are the two criteria for whether a change is chemical or physical?
Oxygen and hydrogen
When an electric current passes through water takes place breaking down the compound into hydrogen and oxygen. a physical change an atomic change a chemical change an elemental change?
When an electric current passes through water, it breaks down the compound into hydrogen and oxygen, which is known as electrolysis. This process involves the breaking of chemical bonds and the formation of new substances, indicating a chemical change. Thus, the correct answer is a chemical change.
Is formation of water from its element physical change?
No, the formation of water from its elements (hydrogen and oxygen) is a chemical change because new substances with different properties are formed. In this case, a chemical reaction occurs between hydrogen and oxygen molecules to produce water molecules.
What is one example of a chemical change?
Burning hydrogen (hydrogen + oxygen -> water: 2H2 + O2 => 2H2O)
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 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
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.
