i have no idea i asked you!!
Oxidation is a chemical reaction; but a physical modification can also occur.
No, it is a physical reaction because it doesn't undergo any change in chemical properties.
The reactants undergo a chemical reaction and form new products with different physical and chemical properties.
Oxidation is a chemical reaction; but a physical modification can also occur.
When a aluminum can is crushed, it undergoes a physical change, because even though the object got crushed and misshaped it still has the same identity.The identity has never changed.

A "chemical" change takes place when an acid dissolves soft rock. A "physical change" occurs when a rock is crushed into powder.
Both, sorta. The explosion itself is expanding hot gas, which is a purely physical reaction. However, most of the time, that's triggered by a chemical reaction to create the heat.
Yes silicon can undergo physical and chemical changes.
Catalysts doesn't undergo a chemical change during a chemical reaction.
