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.

Photosynthesis is the chemical change of the suns energy into glucose and oxygen.
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.
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.
