What else can I help you with?
What would happen if platinum was added to hydrogen peroxide solution?
Platinum acts as a catalyst in the presence of hydrogen peroxide, accelerating the decomposition of hydrogen peroxide into water and oxygen gas. This reaction produces bubbles of oxygen gas, causing the solution to foam or fizz. The platinum itself does not react and remains unchanged at the end of the reaction.
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 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.
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.
What is oxygen in a chemical change that produces water?
The reaction between oxygen and hydrogen produce water.
What would you expect to see if platinum were added to hydrogen peroxide solution?
If platinum were added to hydrogen peroxide solution, you would likely observe bubbles of oxygen gas being produced. Platinum can act as a catalyst to help decompose hydrogen peroxide into water and oxygen.
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.
Can water be separated into hydrogen and oxygen by boil physical change or chemical change?
Water can be separated into hydrogen and oxygen through a chemical change called electrolysis, which uses an electric current to break apart the water molecules. Boiling water is a physical change that only changes the state of the water from liquid to gas, but it does not separate the water into its component elements.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.
Is hydrogen and oxygen combining to form water and example of a physical change?
No, it is not.
When hydrogen and oxygen conforms to water what would water be considered and what would hydrogen and oxygen be considered?
Hydrogen and oxygen are the reactants and water is the product.
Is decomposing water physical or chemical change?
Chemical change; bonds are broken when water decomposes into hydrogen and oxygen.
