Is gold plating chemical reaction or physical reaction?
Gold plating on non-metals is a physical change. There is no chemical change when a wood, glass, ceramic, marble or plastic is being plated . However, Electroplating is a chemical change because when a metal is being plated with another metal, there is a chemical reaction.
Is electroplating physical or chemical change?
Electroplating involves a combination of physical and chemical changes. The metal ions (chemical change) in the solution are reduced and deposited onto the object's surface using electricity (physical process).
Is a metal surface being ground a chemical change?
A metal Surface being ground is a physical change, not a chemical change.
Is mixing nitric and copper metal a physical change?
Mixing nitric acid with copper metal is a chemical change, as a reaction between the nitric acid and the copper metal occurs, resulting in the formation of copper(II) nitrate, nitrogen dioxide gas, and water. This chemical reaction involves the breaking and formation of chemical bonds, leading to the formation of new substances with different properties.
Is electroplating a chemical or physical change?
Electroplating is a chemical change. Solutions containing metal ions are placed in a tank, and the piece of metal to be plated is connected to the electrical supply to become the cathode. The metal ions in solution are attracted to the cathode where they are reduced (reduction is gain of electrons) to form a metal coating.

Is pounded metal a physical or chemical change?
Physical change
When you add zinc metal to hyrochloric acid does a chemical physical change occur?
Yes, hydrogen gas and zinc chloride are produced

Is corrosion of a piece of metal chemical or physical change?
chemical change
Is bending metal sheets a chemical change?
No. It is a physical change because the chemical composition of the metal remains the same.
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 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.
Is metal corroding a physical change or chemical change?
Corrosion is a chemical change
Is electro plating a physical or chemical change?
Galvanizing is a physical change. This is because the zinc is coated on the Iron using the magnetic properties of the elements. In the chemical changes a new substance is formed, here the zinc only forms a layer on the Iron,
