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.
Is giving off light a physical or chemical change?
I would think it to be a Physical Change. Not chemical.
Plants changing carbon dioxide and water into sugar and oxygen a physical or chemical change?
Yes it is chemical because the sun is producing food by causing chemicals and substances
Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical change
Is a cut healing a physical or chemical change?
Chemical. The hydrogen peroxide breaks down into water and elemental oxygen. Two new substances are created.
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 magnesium is burning in the presence of oxygen what are some evidence that a chemical change is occurring?
Some evidence that a chemical change is occurring when magnesium is burning in the presence of oxygen include the formation of a white powdery substance (magnesium oxide), the emission of light and heat, and the change in physical properties of the magnesium (e.g., color change or formation of ash).
Is flammability of a substance is physical or chemical change?
Stating that something is flammable is stating a chemical property. But the actual burning would be a chemical change.
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.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
Is the condensation of oxygen gas a chemical change or physical change?
It is a physical change.
If leaves producing oxygen a chemical or physical change?
That would be a chemical change.
Is Oxygen and hydrogen combining to form water physical or chemical change?
This is a chemical change.
is iron rusts a chemical or physical change?
The rusting of iron is a chemical change. It involves the reaction of iron with oxygen in the presence of moisture to form iron oxide (rust), which has different chemical properties compared to the original iron.
Reaction with oxygen is a physical or a chemical change?
Oxidation is a chemical process.
Is heating mercuric oxide a physical or chemical change?
This is a chemical reaction; oxygen is released.
Is rusting of iron a physical or chemical change?
Rusting of iron is a chemical change. It occurs when iron reacts with oxygen and water in the presence of moisture, forming iron oxide (rust). This process involves a chemical reaction that changes the chemical composition of the iron.
