What else can I help you with?
Is oxide formation a physical change?
No. It is a chemical change.
What is Heating up metal with a flame is that a physical or chemical change?
No, it is a chemical change. The metal oxide formed is a new substance.
Is rusting of an iron fence a physical change?
No, it is a chemical change (conversion to iron oxide)
Is burning magnesium oxide a chemical change or physical?
Burning magnesium oxide is a chemical change because it involves a chemical reaction where the magnesium oxide is converted to a new substance (magnesium oxide reacts with oxygen to form magnesium oxide). This process involves the breaking and forming of chemical bonds.
Rusting iron is it physical or chemical change?
Rusting iron is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). This process cannot be easily reversed by physical means.
What is rusting of Iron physical or chemical?
A Chemical change as rust is iron oxide
Is metal roasting a chemical or physical change?
The rusting of metal is a chemical change and not a physical change. This is because iron and water react to form a compound called iron oxide.
Is there a chemical or physical change when a bicycle rusts in the rain?
Rusting is a chemical change, as steel/iron turns into iron oxide.
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 the heating of iron III oxide for sometime a physical or chemical change?
Just heating the metal would be a physical change, as you would only have a warmer iron III oxide. However, if the heat caused a reaction, it would then be a chemical change.
Is heating mercuric oxide a physical or chemical change?
This is a chemical reaction; oxygen is released.
Is corrosion of metals physical or chemical change?
It is a chemical change, where a chemical such as oxygen or chlorine combines with a metal, forming an oxide or chloride of that metal.
