Oxidation originates at the surface of the metal and then it slowly penetrates through the surface.
<em>As at the beginning exposed surface area is more therefore rate of oxidation is also more. After that, the process needed to occur inside the exposed surface of the metal, and the rate of diffusion decreases, so the rate of oxidation decreases.</em>
<em />
<em>It represents oxide layers that reduce the diffusion rate, therefore it is used for producing isolation shields for metals. Apart from that for covering a metal from the external environment or masking oxide layers are produced on metal surfaces.</em>

Mass is a quantitative measure of inertia, an essential property of all dependents. It's far, in effect, the resistance that a frame of count number gives to a change in its speed or position upon the application of pressure. The more the mass of a frame, the smaller the alternate produced with the aid of a carried-out force.

<u>Answer:</u>
The freezing point of a 1.7 mole aqueous ethylene glycol solution is 3.2°C
<u>Explanation:</u>
Moles present in aqueous ethylene glycol solution= m=1.7
Depression constant for water = = 1.8 deg C/m
According to formula
=1.8* 1.7
=3.2
Hence the freezing point of aqueous ethylene glycol solution is 3.2°C
