Is forming ozone from oxygen a chemical change?
Putting oxygen in tanks (under pressure) is a physical change, not a chemical change. The chemical nature of the oxygen has not been altered, and it is possible to recover the original substance, thus it is not a chemical change.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
The chemical change of the sun's energy into glucose and oxygen-?
Photosynthesis is the chemical change of the suns energy into glucose and oxygen.
Is heating mercuric oxide a physical or chemical change?
This is a chemical reaction; oxygen is released.
Is oxygen a chemical change or a physical?
Oxygen is a chemical element, so its presence does not involve a chemical change. It undergoes physical changes such as changes in state (gas to liquid) based on temperature and pressure.
When the fuse ignited the contents of a firework oxygen is consumed as a result of which type of change?
chemical
What is an example of a chemical change?
frying an egg
If a balloon filled with hydrogen gas explodes upon contact with a spark a chemical or physical change?
The explosion of a balloon filled with hydrogen gas upon contact with a spark is a chemical change. This is because the hydrogen gas (H₂) reacts with oxygen (O₂) in the air to form water (H₂O) and release energy in the form of an explosion.

The chemical change of glucose and oxygen into energy -?
The chemical change of glucose and oxygen into energy is called fermentation.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
Hydrogen can explode when ignited in air is physical property?
Yes, the fact that hydrogen can explode when ignited in air is a chemical property. It is a characteristic of hydrogen's reactivity with oxygen that results in a combustion reaction, producing energy in the form of heat and light.
The chemical change of the sun's energy into glucose and oxygen-?
Photosynthesis is the chemical change of the suns energy into glucose and oxygen.
Is heating mercuric oxide a physical or chemical change?
This is a chemical reaction; oxygen is released.
If leaves producing oxygen a chemical or physical change?
That would be a chemical change.
Is oxygen a chemical change or a physical?
Oxygen is a chemical element, so its presence does not involve a chemical change. It undergoes physical changes such as changes in state (gas to liquid) based on temperature and pressure.
When oxygen is liquefied is it a physical or chemical change?
Physical because it is still Oxygen. A chemical change results in a chemical equation and thus a new substance. No new substance = no chemical change. Liquefaction is a physical property.
