What is the definition of electroplating?
Electroplating is a process of depositing a thin layer of one metal over another metal by the method of electrolysis.
Why does tin protects iron from corrosion?
Tin protects iron from corrosion through a process called sacrificial protection, where the tin acts as a sacrificial anode and corrodes instead of the iron. The tin forms a protective layer over the iron, preventing exposure to moisture and oxygen which are necessary for corrosion to occur. This sacrificial layer of tin can be periodically replaced to maintain the protective barrier.
Where has ozone layer decreased and why?
Ozone layer is depletion is happening in the stratosphere of the earth's atmosphere. It is majorly concentrated over Antarctica's atmosphere. The substances that are causing ozone layer depletion are freons, CFC's etc.. These are called as ozone-depleting substances (ODS).
Where does the ozone layer start?
The ozone layer does not start anywhere. It is a complete layer spread all over.
What mean ozen layer?
Ozone layer is a protective layer over the earth. It protects us from the UV rays of the sun.
How does galvanise prevent rusting?
The process of depositing a layer of zinc over iron from preventing it to rust is called galvanisation. Galvanisation does not let iron come in contact with oxygen so it does not allow it to rust and corrode. Since, iron does not come in contact with oxygen it doesn't react.

What product is formed when iron rusts?
Rust is nothing but Ferrous oxide, also known as iron oxide, Iron (III) oxide, or Fe2O3. The outermost layer of the iron, which is in contact with the atmosphere, attracts oxygen and forms iron oxide which is called rusting. The rust itself forms a layer over the iron and prevents further iron oxide formation. When iron rusts the red substance formed is actually a mixture of Hydrated Iron(III) oxides and hydroxides.

What are rocks that form layer by layer over many years called?
They are called sedimentary rocks.
What is the name of the layer over Los angles that holds in the smog?
The layer of air over L.A. that holds in smog is called an inversion layer.
Why iron does not react with nitric acid?
Nitric acid is oxidizing acid. When it reacts with iron it forms a protective layer of iron oxide over it. So it does not react further.
What is the layer over the paint on a car called?
Clearcoat.
Do not iron on decoration?
Generally it means do not iron directly over the decoration on the clothing because the heat can ruin it. Most of the time, if you put another layer between the iron and decoration, you can iron it, but do not get the decoration too hot.
Which layer of skin is true skin?
The dermis is often called the true skin. It has a layer over it called the epidermis and one below it that has a lot of fat cells. That is called the subcutaneous layer. (cutaneous means skin).
What is the white reflective layer put over the glue layer that acts as a primer on the painting panel called?
Gesso
What is the process called to make iron?
There are several methods or processes of making iron - smelting, wrought iron, cast iron and so on, which have evolved over many years.
