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
What is one example of a chemical change?
Burning hydrogen (hydrogen + oxygen -> water: 2H2 + O2 => 2H2O)
Is decomposition a physical or chemical property?
Decomposition is the process of a compound breaking up into the elements it was comprised of. For example, in electrolysis water decomposes to create hydrogen and oxygen. Because the chemical bonds holding the hydrogen and oxygen molecules were broken, decomposition is a chemical change.
Justify why electrolysis of water is a chemical irreversible change?
A chemical change is always irreversible; that's part of the definition of "chemical change". This is because a new substances with new properties are formed. In this example, hydrogen and oxygen 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 hydrogen burning a physical or chemical change?
burning in presence or absence of oxygen is a chemical change.
Is hydrogen burns in chlorine gas chemical or physical change?
When you combust hydrogen in air, the hydrogen will combine with oxygen to form water. Therefore, the hydrogen and oxygen are undergoing a chemical change to become bonded together producing H2O: 2H2 + O2 → 2H2O + Heat
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 using electricity to separate water into hydrogen and oxygen a chemical change?
physical change
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 it a chemical or physical change when a scientist break-up water into oxygen and hydrogen gas?
It would be chemical change.
