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.

Answer: The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. Hope this is what your looking for.
Explanation:
I think it’s D but I’m not sure
Answer: Use of Etherificarion followed by fractional distinction.
Explanation:
It is done by reacting a mixture of tetrahydrofurfuryl alcohol and up to about one equivalent of at least one low work function element, Reacting the said mixture with a halide; fractionally distilling said reacted mixture to yield the first distillate; reacting said first distillate with an excess amount of at least one low work function element; and, fractionally distilling said reacted first distillate to obtain the purified ether wherein said at least one low work function element is an elemental metal or a metal hydride which has a φ of less than about 3.0 eV.
Answer:
<h2>7.54 atm </h2>
Explanation:
The required pressure can be found by using the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have
We have the final answer as
<h3>7.54 atm </h3>
Hope this helps you
