Both. A chemical reaction occurs & a physical change is noticeable.
What else can I help you with?
IS oxidizing of mercury a chemical change?
Yes, the oxidizing of mercury is a chemical change. During this process, mercury reacts with an oxidizing agent to form mercury compounds, such as mercury(II) oxide, which results in a change in the chemical composition of the substance. This transformation cannot be reversed by simple physical means, further confirming its classification as a chemical change.
Is oxidizing mercury a physical or chemical change?
Oxidizing mercury is a chemical change because it involves a rearrangement of atoms in the mercury molecules to form new compounds (such as mercury oxide). This results in a change in the chemical composition of the substance.
Is oxidizing a physical or chemical change?
Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.
Is oxidizing physical change?
Oxidation and reduction are chemical changes.
Is mercury expanding in a thermometer a chemical or physical change?
Physical. The mercury doesn't change.
Is darkening of cut apple physical change?
It's a chemical change because the apple is oxidizing. It turns brown, because of the oxygen, hence the word " oxidizing".
Is the Statue of Liberty a physical change or a chemical change?
No its a chemical change because the acid in the rain reacts with the copper in the statue having a reaction oxidizing it and turning it green.
Is oxidizing a chemical or physical property?
It is a chemical because it is producing a new substance.
Is heating mercuric oxide a physical or chemical change?
This is a chemical reaction; oxygen is released.
How is freezing mercury a reversable physical change?
During freezing the chemical nature of mercury remain unchanged.
Is mercury being heated to produce mercury vapor a physical change?
Yes, heating mercury to produce mercury vapor is a physical change because no new substances are formed. The change is reversible, and the mercury can return to its original state once cooled back down.
Is it a physical or chemical change when the liquid mercury in a thermometer expands as it is heated?
physical change
