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.
Do oxygen and hydrogen and carbon dioxide weigh the same?
No, oxygen, hydrogen, and carbon dioxide do not weigh the same. They have different atomic masses, with oxygen being heavier than hydrogen and carbon dioxide being heavier than both oxygen and hydrogen.
Is hair being bleached with hydrogen peroxide a chemical property?
Hair being bleached with hydrogen peroxide is a chemical change, not a chemical property. Chemical properties describe how a substance reacts with other substances to form new substances, while a chemical change involves the actual rearrangement of atoms and molecules in a substance. In this case, hydrogen peroxide is breaking down the pigment molecules in the hair, causing it to change color.
How is a sample oxygen different from a sample of a water?
A sample of oxygen is a pure gas composed of oxygen molecules (O2), while a sample of water is a liquid composed of hydrogen and oxygen atoms (H2O). These substances have different physical properties and chemical compositions, with oxygen being a gas and water being a liquid at room temperature.
Why hydrogen peroxide act as oxidizing agent?
Hydrogen peroxide is H2O2, so, when it reacts upon touching a surface such as your skin it releases 1 oxygen atom thereby converting the H2O2 to H20. The now free Oxygen atom, being highly chemically reactive oxidizes the surface it is in contact with.

What are the variables for oxygen BEING slpit into hydrogen?
Oxygen cannot be split into hydrogen.

When a forklift battery is being charged it produces oxygen and what else?
Hydrogen

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.
When a battery is being charged it produces oxygen and what?
hydrogen
Is hydrogen water?
No, hydrogen is an element. It is one of the components of water, the other being oxygen.
What is one example of a chemical change?
Burning hydrogen (hydrogen + oxygen -> water: 2H2 + O2 => 2H2O)

What does a forklift battery produce when its being charged?
Oxygen and hydrogen
