Oxidation is loss of electrons from a substance, and Reduction is gain of electrons by a substance.
These two processes cannot occur without the other. If there is a reduction there must be an oxidation reaction and vice versa. The reactions usually occur simultaneously.
For example, table salt is formed by a redox reaction. Sodium is oxidized i.e. loses an electron (and becomes positively charged) while chlorine gas is reduced i.e. gains the electron (and become negatively charged). The result is formation of sodium chloride.
it represents a physical change. it is not a chemical change because its chemical formula does not change unless combustion is involved.

Answer:
Moisture content in wet basis = 47.4 %
Explanation:
<u>Moisture content expresses the amount of water present in a moist sample.</u> <u>Dry basis and wet basis are widely used to express moisture content. </u>
The next equation express the moisture content in wet basis:
<em>where, : moisture content in wet basis and </em>
<em> : moisture content in dry basis </em>
We now calculate the moisture content in wet basis:
= 0.474 = 47.4 % wet basis
Have a nice day!
No in that case it would be a chemical change
